WhisperKOOL Mini Ductless Airflow Kit with 2 Airflow Deflectors – 03-DEFLECTOR-KIT-MIN
Important: This add-on accessory cannot be purchased without the compatible main unit.
The WhisperKOOL Mini Ductless Airflow Kit, model 03-DEFLECTOR-KIT-MIN, is designed specifically for a compatible WhisperKOOL Mini Blow-Through evaporator. The kit includes two directional airflow deflectors that allow the evaporator's return and supply air paths to communicate directly with the wine cellar without field-installed supply or return duct runs.
One deflector is installed on the return-air side of the Mini evaporator, while the second is installed on the conditioned supply-air side. The rotatable design supports multiple approved airflow orientations, allowing the project team to direct return and supply airflow toward the front, toward the back, or downward according to the selected installation configuration.
Product Summary
The WhisperKOOL 03-DEFLECTOR-KIT-MIN is the Mini-specific ductless airflow kit for the WhisperKOOL Blow-Through Series. It includes two rotatable airflow deflectors: one for the return side and one for the supply side of the Mini evaporator.
Unlike the fully ducted kit, this accessory does not connect the evaporator to long supply and return ducts. Instead, it directs air between the concealed Mini evaporator and the wine cellar through adjacent, correctly sized cellar openings. WhisperKOOL supports nine ductless orientation combinations so the return and supply air can be directed downward, toward the front, toward the back, or in selected mixed configurations.

What Is the Mini Ductless Airflow Kit?
The 03-DEFLECTOR-KIT-MIN provides the two Mini-specific airflow components needed to create a ductless, or deflector-style, airflow arrangement for the WhisperKOOL Mini Blow-Through evaporator.
In this configuration, warmer cellar air enters the return-side deflector and passes through the Mini evaporator. After heat is removed, conditioned air exits through the supply-side deflector and is directed back into the wine cellar.
Because the airflow travels directly between the evaporator and cellar openings, separate field-installed supply and return duct runs are not used. The evaporator must therefore be positioned immediately adjacent to the cellar openings in a properly designed soffit, cabinetry cavity, wine wall, millwork enclosure, or other suitable installation location.
How the Two Airflow Deflectors Work
| Deflector | Function | Airflow Role |
|---|---|---|
| Return-Air Deflector | Directs warmer cellar air toward the evaporator return opening. | Helps the evaporator capture air that must be cooled. |
| Supply-Air Deflector | Directs conditioned air from the evaporator back into the wine cellar. | Helps distribute cooled air into the storage space. |
The two deflectors must be installed in the correct return and supply positions. Their final direction should be selected before the evaporator is permanently mounted or enclosed.
Proper airflow planning remains essential even though long ducts are not used. Supply air must be able to circulate through the cellar before returning to the return opening. Poor orientation can cause immediate recirculation, uneven temperatures, excessive system runtime, or inadequate cooling.
Benefits of the Mini Ductless Airflow Kit
No Field-Installed Supply or Return Duct Runs
The deflectors allow the Mini evaporator to communicate directly with the wine cellar. This eliminates the need to route separate insulated supply and return ducts through the building.
Multiple Directional Airflow Options
The rotatable deflectors support several return-and-supply orientation combinations. Depending on the physical installation, airflow may be directed downward, toward the front, toward the back, or in an approved mixed-direction arrangement.
Supports Concealed Installations
The Mini Blow-Through evaporator can be positioned in a soffit, cabinetry cavity, wine wall, overhead enclosure, or adjacent concealed space while the deflectors direct air through planned cellar openings.
Reduces Duct-Related Airflow Resistance
Because the ductless configuration does not use extended supply and return duct runs, it avoids the additional airflow resistance created by long ducts, compressed flexible duct, elbows, transitions, and restrictive duct fittings.
Supports Clean Wine Cellar Design
When integrated correctly, the airflow openings may be concealed behind compatible custom grilles or millwork so the wine display remains the visual focus of the room.
Mini-Specific Fit
The 03-DEFLECTOR-KIT-MIN is intended for the dimensions and airflow arrangement of the Mini Blow-Through evaporator. It should not be treated as interchangeable with the deflectors for the larger Blow-Through 4000 or 8000 systems.
Nine Supported Ductless Airflow Configurations
WhisperKOOL publishes nine ductless configurations for the Blow-Through deflector arrangement. These options allow the return-air and supply-air deflectors to be oriented according to the physical position of the evaporator and the cellar openings.
| Configuration | Return-Air Direction | Supply-Air Direction |
|---|---|---|
| Ductless Configuration 1 | Downward | Downward |
| Ductless Configuration 2 | Toward the back of the unit | Downward |
| Ductless Configuration 3 | Downward | Toward the back of the unit |
| Ductless Configuration 4 | Downward | Toward the front of the unit |
| Ductless Configuration 5 | Toward the front of the unit | Downward |
| Ductless Configuration 6 | Toward the front of the unit | Toward the front of the unit |
| Ductless Configuration 7 | Toward the back of the unit | Toward the back of the unit |
| Ductless Configuration 8 | Toward the front of the unit | Toward the back of the unit |
| Ductless Configuration 9 | Toward the back of the unit | Toward the front of the unit |
Choosing the Correct Deflector Direction
The best orientation depends on where the Mini evaporator is placed relative to the wine cellar and how the return and supply openings are positioned.
Downward Airflow
A downward-facing deflector may be used when the evaporator is concealed above the wine cellar, such as inside a ceiling soffit or overhead millwork enclosure. The cellar opening must align with the deflector and provide an unobstructed path for airflow.
Front-Facing Airflow
A front-facing deflector may be appropriate when the cellar opening is positioned directly in front of the corresponding side of the evaporator.
Rear-Facing Airflow
A rear-facing deflector may be used when the corresponding cellar opening is located behind the evaporator relative to its installed orientation.
Mixed Return and Supply Directions
The return and supply deflectors do not always need to face the same direction. WhisperKOOL provides approved mixed arrangements where one deflector points downward and the other faces front or back, or where the return and supply face opposite directions.
Mixed orientations can provide additional installation flexibility, but they must still create an effective airflow path through the wine cellar.
Recommended Applications
| Application | How the Mini Ductless Kit Supports the Project |
|---|---|
| Overhead wine cellar soffits | Allows the Mini evaporator to remain above the cellar while the deflectors direct return and supply air through nearby openings. |
| Built-in wine cabinetry | Supports integration into custom cabinetry when airflow openings and service access are incorporated into the design. |
| Wine walls | Provides directional airflow for compact displays where long duct runs are unnecessary or impractical. |
| Custom millwork enclosures | Allows the evaporator to be concealed behind architectural finishes while directing air through correctly sized openings. |
| Glass-enclosed wine rooms | Helps keep equipment discreet when the system has been properly sized for the additional heat load created by glass. |
| Residential wine displays | Supports a clean, integrated appearance without extended supply and return ducts. |
| Restaurant wine displays | Allows cooling equipment to remain less visible in customer-facing wine storage areas. |
| Hospitality wine storage | Supports concealed installations in tasting rooms, lounges, and display cellars where nearby direct airflow openings are possible. |
Who Should Choose the Mini Ductless Airflow Kit?
Choose the 03-DEFLECTOR-KIT-MIN when a compatible Mini Blow-Through evaporator will be installed immediately adjacent to the wine cellar and both the return and supply sides can use direct airflow openings.
This Kit Is a Strong Fit When:
- The project uses a compatible WhisperKOOL Mini Blow-Through evaporator.
- Both the return and supply sides will use airflow deflectors.
- No extended supply or return ducts are required.
- The evaporator can be positioned directly beside or above the cellar openings.
- The installation requires front, rear, downward, or mixed-direction airflow.
- The deflectors can remain correctly aligned with the finished openings.
- The openings can remain unobstructed after wine racks and finishes are installed.
- The evaporator and deflectors can be properly insulated.
- The installation will retain adequate service and maintenance access.
This Kit May Not Be Appropriate When:
- The evaporator must be installed a significant distance from the cellar.
- Both airflow paths require field-installed duct runs.
- Only one side requires a deflector and the other side requires ducting.
- The installed evaporator is a Blow-Through 4000 or 8000 rather than a Mini.
- The soffit or cabinet cannot provide correctly aligned airflow openings.
- Wine racks, trim, bottles, or cabinetry would block the airflow path.
- The return and supply openings would cause immediate air recirculation.
- The evaporator would be permanently enclosed without service access.
Mini Blow-Through Compatibility
The 03-DEFLECTOR-KIT-MIN is designed specifically for a compatible WhisperKOOL Mini Blow-Through evaporator. The Mini uses a different deflector arrangement from the larger Blow-Through 4000 and 8000 evaporators.
| Component | Compatibility Requirement |
|---|---|
| Evaporator | Compatible WhisperKOOL Mini Blow-Through evaporator |
| Return Deflector | Mini-specific airflow deflector included with this kit |
| Supply Deflector | Mini-specific airflow deflector included with this kit |
| Airflow Configuration | Fully ductless return and supply arrangement |
| Deflector Insulation | Must be installed according to the owner's manual |
| Cellar Openings | Must align with the selected return and supply directions |
Cellar Opening and Grille Requirements
Although the Mini Ductless Airflow Kit does not require supply and return duct runs, the evaporator still requires correctly positioned openings between the concealed installation area and the wine cellar.
These openings must align with the selected deflector directions and provide enough unobstructed area for return and supply airflow. Decorative grilles, louvers, trim, and millwork must not excessively restrict the openings.
Opening and Grille Planning Guidelines
- Plan the return and supply openings before constructing the soffit or cabinetry.
- Align each opening with its corresponding airflow deflector.
- Do not offset the opening in a way that blocks or sharply redirects airflow.
- Keep the deflector outlet clear of framing, trim, insulation, and wiring.
- Use decorative grilles with adequate open area.
- Avoid tightly spaced blades, restrictive mesh, screens, foam, or solid backing.
- Do not allow paint, stain, trim, or sealant to close the finished openings.
- Keep openings clear of wine bottles, cases, racks, furniture, and stored materials.
- Confirm the finished opening dimensions before the evaporator is enclosed.
- Verify unobstructed return and supply airflow during commissioning.
A decorative grille may appear large while still providing limited usable open area. The project team should evaluate the actual free area rather than relying only on the grille's outside dimensions.
Return and Supply Air Separation
Return and supply air must form an effective circulation path through the wine cellar. The conditioned supply air should travel through the storage space before being drawn back into the return opening.
Avoid Immediate Recirculation
Immediate recirculation occurs when the supply air is drawn directly into the return opening before it has circulated through the cellar. This can cause the cooling system to sense a misleadingly low return-air temperature while distant parts of the cellar remain warmer.
Keep Both Air Paths Clear
Wine bottles, cases, racking, cabinet panels, lighting components, and decorative trim must not block either deflector. The final room layout should be reviewed together with the cooling-system airflow plan.
Position the Evaporator High
The complete Mini Blow-Through installation should follow the manufacturer's guidance for locating the evaporator high in the conditioned space so it can capture warmer air that naturally rises.
Deflector and Evaporator Insulation Requirements
The two Mini airflow deflectors must be insulated according to the official WhisperKOOL installation instructions. The evaporator must also receive the manufacturer-supplied insulation blanket and the additional insulation required for the installed location.
These requirements are important because the evaporator and deflector surfaces may operate below the dew point of surrounding warm or humid air. Uninsulated surfaces can develop condensation that may damage the equipment, soffit, cabinetry, ceiling, or nearby building materials.
Insulation Checklist
- Install the manufacturer-supplied insulation on both Mini deflectors.
- Install the supplied insulation blanket around the evaporator as instructed.
- Add the specified fiberglass insulation around the exterior evaporator cavity.
- Insulate the space between ceiling joists where applicable.
- Maintain a continuous vapor-resistant enclosure around cold surfaces.
- Seal gaps around airflow openings and penetrations.
- Do not leave exposed cold metal in a warm soffit, attic, or cabinet cavity.
- Inspect the finished installation for gaps before closing the enclosure.
- Maintain access so insulation can be inspected during future service.
Installation Overview
Installation of the 03-DEFLECTOR-KIT-MIN must be coordinated with the complete Mini Blow-Through installation. The return and supply orientations, evaporator position, cellar openings, insulation, drainage, refrigeration piping, wiring, controls, structural support, and service access should be determined before the equipment is enclosed.

It is a Mini-specific ductless airflow accessory kit for a compatible WhisperKOOL Mini Blow-Through evaporator. It uses two directional airflow deflectors instead of two duct plenums.
How many airflow deflectors are included?
The kit includes two Mini airflow deflectors. One is used on the return-air side and the other is used on the conditioned supply-air side.
Is the 03-DEFLECTOR-KIT-MIN a complete wine cooling system?
No. It is an airflow accessory only. The Mini Blow-Through evaporator, condensing unit, line set, wiring, controls, cellar construction, and professional installation are not included.
Which evaporator is compatible with this kit?
It is designed specifically for a compatible WhisperKOOL Mini Blow-Through evaporator.
Can this kit be used with the Blow-Through 4000 or 8000?
No. The Mini and larger Blow-Through evaporators use different deflector arrangements. Order the airflow kit specified for the exact evaporator model.
What does ductless airflow mean?
Ductless airflow means the evaporator's return and supply sides direct air through nearby cellar openings using deflectors rather than through extended field-installed ducts.
Does ductless mean the evaporator can be installed anywhere?
No. The evaporator must be positioned immediately adjacent to correctly planned cellar openings because there are no ducts carrying the return and supply air over a distance.
Are supply and return ducts required?
No. The fully ductless Mini arrangement uses two airflow deflectors and does not require separate supply and return duct runs.
Are duct plenums included?
No. This kit includes airflow deflectors, not duct plenums. Choose the Mini Ducted Airflow Kit when both sides must connect to ducts.
Can the deflectors point downward?
Yes. WhisperKOOL publishes configurations where both deflectors point downward or where only the return or supply deflector points downward.
Can the deflectors face the front or back?
Yes. The supported configurations include front-facing, rear-facing, downward, and mixed-direction arrangements.
How many ductless configurations are available?
WhisperKOOL publishes nine ductless configurations that combine front, back, and downward return-and-supply directions.
Can the return and supply deflectors point in different directions?
Yes. Several approved configurations use different return and supply directions. The final arrangement must match the official configuration guide and the physical installation.
Can the Mini evaporator be hidden in a soffit?
Yes, when the soffit provides suitable structural support, correctly positioned airflow openings, required insulation, condensate management, and service access.
Can this kit be used in custom cabinetry?
Yes. The kit can support custom cabinet and wine-wall installations when the airflow openings are correctly aligned and the evaporator remains accessible for service.
Can decorative grilles be installed over the openings?
Decorative grilles may be used when they provide sufficient open area and do not substantially restrict return or supply airflow.
Are decorative grilles included?
No. Custom grilles, louvers, trim, and millwork are supplied separately for the specific cellar design.
Do the airflow deflectors require insulation?
Yes. The deflector pieces must be insulated according to the official WhisperKOOL owner's manual.
Why is deflector insulation important?
The deflectors may carry air below the dew point of the surrounding space. Proper insulation helps reduce condensation, moisture damage, corrosion, and heat gain.
Does the Mini evaporator also need insulation?
Yes. The evaporator requires the supplied insulation blanket and the additional insulation specified by WhisperKOOL for the installed location.
How should the return and supply openings be positioned?
They should align with the selected deflector directions and create an effective circulation path through the wine cellar without allowing supply air to return immediately to the evaporator.
What can block ductless airflow?
Restrictive grilles, narrow openings, framing, insulation, trim, wine racks, bottles, cases, furniture, or stored materials can interfere with airflow.
Is the ductless kit better than the ducted kit?
Neither arrangement is universally better. The ductless kit is suitable when the evaporator can sit directly beside the cellar openings. The ducted kit is used when airflow must travel between the evaporator and remote registers.
When should I choose a hybrid airflow kit instead?
Choose a hybrid kit when one side of the Mini evaporator can use a direct deflector while the other side must connect to ductwork.
Does this accessory increase cooling capacity?
No. It controls the direction and connection of airflow. It does not increase the refrigeration capacity of the Mini Blow-Through system.
Can this kit correct an undersized cooling system?
No. The complete cooling system must be selected through an appropriate wine cellar heat-load calculation. An airflow kit cannot compensate for an undersized evaporator or condenser.
Can this kit be used for a glass wine cellar?
It can be used as part of a properly designed glass-cellar system, but glass increases the heat load. The complete Mini cooling system must be confirmed as suitable through a project-specific heat-load calculation.
Does the Mini Ductless Airflow Kit require professional installation?
Yes. It must be coordinated with the installation of the complete Mini Blow-Through split system, which requires a qualified HVAC-R technician.
Can the evaporator be permanently sealed behind drywall?
No. The installation must retain suitable access for inspection, cleaning, condensate service, refrigeration service, electrical testing, and component replacement.
What should be confirmed before ordering?
Confirm the Mini evaporator model, the need for two deflectors, the selected airflow directions, cellar-opening locations, available insulation space, and future service access.
Important Ordering Guidance
Before ordering the WhisperKOOL Mini Ductless Airflow Kit 03-DEFLECTOR-KIT-MIN, confirm that the project uses a compatible Mini Blow-Through evaporator and that both the return and supply sides will communicate directly with the wine cellar through airflow deflectors.
