WhisperKOOL 4000/8000 Ductless Airflow Kit – 2 Airflow Deflectors
Important Note: This Add-on Accessory cannot be purchase without the Main Unit.
The WhisperKOOL 4000/8000 Ductless Airflow Kit, model 03-DEFLECTOR-KIT-LRG, is the required airflow configuration kit for compatible Blow-Through 4000 and Blow-Through 8000 evaporators installed without supply or return ductwork.
The kit includes two airflow deflectors: one for the conditioned-air supply side and one for the cellar-air return side. The deflectors attach directly to the compatible Blow-Through evaporator and allow air to move between the cooling unit and wine cellar without separate duct runs.
Choose this kit when the Blow-Through evaporator will be positioned in or immediately adjacent to the conditioned space and both supply and return air can be directed through open, unrestricted pathways. It is especially useful for soffit, cabinetry, wine-wall, and other concealed installations where traditional ductwork is unnecessary or impractical.
Quick Answer
The 03-DEFLECTOR-KIT-LRG converts a compatible WhisperKOOL Blow-Through 4000 or 8000 evaporator to a fully ductless airflow configuration. It includes two deflectors that direct supply and return air without requiring evaporator ductwork.

Why Choose the Ductless Airflow Kit?
Eliminates Evaporator Duct Runs
The two deflectors allow the compatible evaporator to exchange air directly with the cellar. This can simplify projects where there is not enough space for insulated supply and return ductwork.
Supports Concealed Installations
The kit can be used in installations where the evaporator is hidden inside a soffit, architectural enclosure, custom cabinetry, or another nearby location with properly designed openings for supply and return airflow.
Directs Supply and Return Air
One deflector is installed on the conditioned-air side of the evaporator, while the second is installed on the return-air side. Their purpose is to direct airflow through the selected openings and help prevent uncontrolled discharge inside the equipment cavity.
Designed for the Larger Blow-Through Models
The 03-DEFLECTOR-KIT-LRG is intended for compatible Blow-Through 4000 and 8000 evaporators. It should not be substituted for the smaller deflector kit used with the Blow-Through Mini.
Maintains System Configuration Flexibility
WhisperKOOL Blow-Through evaporators can be configured as ducted, ductless, or hybrid systems. This kit is the correct selection when both the supply and return sides will use direct deflectors.
Best Applications
- Soffit-mounted Blow-Through evaporators
- Custom wine cabinetry
- Built-in wine walls
- Glass-enclosed wine displays
- Mechanical cavities immediately adjacent to the cellar
- Projects with insufficient space for two insulated duct runs
- Installations requiring direct supply and return airflow
- Architectural designs where the evaporator must remain visually concealed
The surrounding enclosure must provide open, unrestricted pathways for both supply and return air. Decorative panels, registers, louvers, trim, screens, or cabinetry openings must not restrict the airflow required by the cooling system.
How the Ductless Configuration Works
A fully ductless Blow-Through installation uses one deflector on each side of the evaporator:
- Return-air deflector: Guides warmer cellar air into the evaporator.
- Supply-air deflector: Directs conditioned air from the evaporator back into the wine cellar.
The deflectors can be oriented according to the approved Blow-Through configuration options. The final orientation should be selected before the evaporator is mounted and before openings are created in soffits, cabinetry, ceilings, walls, or decorative panels.
Supply and return openings should be separated sufficiently to prevent conditioned air from immediately returning to the evaporator. Short cycling of airflow can reduce temperature uniformity and overall system performance.
Ductless vs. Ducted vs. Hybrid Airflow Kits
| Configuration | Included Airflow Components | Best Use |
|---|---|---|
| Ductless | 2 airflow deflectors | Both supply and return air move directly between the evaporator and cellar |
| Ducted | 2 duct plenums | Both supply and return air are routed through insulated ductwork |
| Hybrid | 1 duct plenum and 1 airflow deflector | One air path is ducted while the other uses direct airflow |
Select only the configuration kit that matches the planned evaporator installation. Components from different kits should not be combined unless the resulting arrangement is an approved WhisperKOOL configuration.
Compatibility
The 03-DEFLECTOR-KIT-LRG is designed for use with compatible larger-format WhisperKOOL Blow-Through evaporators, including:
- WhisperKOOL Blow-Through 4000 evaporator configurations
- WhisperKOOL Blow-Through 8000 evaporator configurations
Compatibility should be confirmed using the cooling-system model number and current WhisperKOOL configuration documentation before ordering. This kit is an airflow accessory and does not determine condenser voltage, refrigerant configuration, thermostat type, or pump-down versus communication-cable operation.
What's Included
- 2 large airflow deflectors
The kit is intended to provide the supply-side and return-side airflow components required for a fully ductless installation of a compatible Blow-Through 4000 or 8000 evaporator.
Not Included
- Blow-Through evaporator
- Condensing unit
- Refrigerant line set
- Thermostat or controller
- Condensate drain materials
- Electrical components or field wiring
- Decorative registers or louvers
- Cabinetry, soffit, framing, or finish materials
- HVAC-R installation labor
Installation Considerations
The airflow kit should be installed as part of the complete Blow-Through cooling-system installation. The evaporator, deflectors, surrounding enclosure, cellar openings, drainage, refrigerant piping, electrical service, and service access must be planned together.
Confirm the Airflow Direction
Determine the required supply and return orientation before mounting the evaporator. The deflectors must be positioned so that conditioned air is distributed into the cellar and warm return air can reach the evaporator without obstruction.
Maintain Unrestricted Openings
Do not block the deflectors with wine racks, bottles, cases, decorative panels, trim, screens, insulation, or stored items. Restricted airflow can reduce cooling capacity, increase operating noise, contribute to coil freezing, and create condensate-management problems.
Separate Supply and Return Air
Position the supply and return pathways to promote circulation through the wine cellar. Avoid placing the two openings so close together that conditioned air immediately returns to the evaporator.
Provide Service Access
The surrounding soffit, cabinetry, or enclosure must not prevent access to the Blow-Through evaporator's service panels, refrigerant connections, drainage components, wiring, controller connections, or removable coil sections.
Coordinate with the HVAC-R Installer
The Blow-Through split cooling system must be installed and commissioned by a qualified HVAC-R technician. Airflow configuration should be confirmed with the installer before the cellar or equipment enclosure is completed.
Register and Louver Requirements
When the deflectors discharge or return air through architectural openings, decorative registers, grilles, or louvers, those openings must provide sufficient free airflow. WhisperKOOL's published airflow guidance calls for approximately 50% to 65% open free area across the total register face.
Register dimensions alone do not determine airflow. Slat angle, blade spacing, screens, backing materials, decorative mesh, finish coatings, and interior framing can substantially reduce the actual free area.
Restrictive openings may cause:
- Reduced cooling output
- Higher operating noise
- Increased static pressure
- Evaporator coil freezing
- Condensate overflow or drainage problems
- Uneven cellar temperatures
- Reduced equipment life

Frequently Asked Questions
What is the WhisperKOOL 03-DEFLECTOR-KIT-LRG?
It is a ductless airflow configuration kit for compatible WhisperKOOL Blow-Through 4000 and 8000 evaporators. It includes two airflow deflectors for the supply and return sides of the evaporator.
What is included with the kit?
The kit includes two large airflow deflectors. The cooling system, evaporator, condenser, refrigerant piping, electrical components, drainage materials, registers, and installation labor are not included.
Which Blow-Through models are compatible?
The kit is intended for compatible WhisperKOOL Blow-Through 4000 and Blow-Through 8000 evaporator configurations.
Is this kit compatible with the Blow-Through Mini?
No. The Blow-Through Mini uses a different, smaller airflow deflector kit. Model 03-DEFLECTOR-KIT-LRG is intended for the larger 4000 and 8000 evaporators.
Is this airflow kit required?
Yes, when a compatible Blow-Through 4000 or 8000 evaporator will be installed in a fully ductless configuration. A ducted or hybrid kit should be selected for other approved airflow arrangements.
Does ductless mean the entire cooling system has no ductwork?
The term refers to the evaporator's cellar-side supply and return airflow. A separately installed condenser may still require ducting depending on its model and installation location.
Does this kit include a wine cellar cooling unit?
No. It is an accessory only. A compatible Blow-Through evaporator and the appropriate condensing unit must be purchased separately or as part of a complete cooling-system package.
What is the difference between this kit and the ducted kit?
The ductless kit contains two airflow deflectors for direct supply and return airflow. The ducted kit contains two plenums that connect the evaporator to insulated supply and return ductwork.
What is the difference between this kit and the hybrid kit?
The ductless kit uses two deflectors. The hybrid kit uses one deflector and one duct plenum, allowing one air path to be ducted while the other exchanges air directly with the cellar.
Can the deflectors be used in a soffit installation?
Yes. A soffit is a common application when the evaporator can exchange air directly with the cellar through properly sized and unrestricted openings.
Can the kit be installed inside custom cabinetry?
Yes, provided the cabinetry has adequate supply and return openings, does not restrict airflow, supports the equipment correctly, and allows access for service and maintenance.
Can decorative registers be placed in front of the deflectors?
Decorative registers may be used only when they provide sufficient open free area. WhisperKOOL's airflow guidance calls for approximately 50% to 65% open area across the register face.
Why must the supply and return openings be separated?
Adequate separation helps conditioned air circulate through the cellar before returning to the evaporator. Openings placed too close together can cause airflow short-circuiting and uneven cellar temperatures.
Does the kit affect cooling capacity?
Airflow configuration can affect the published performance of the complete cooling system. Ductless configurations generally avoid the resistance created by long duct runs, but final performance still depends on cellar heat load, evaporator fan speed, airflow restrictions, condenser conditions, and installation quality.
Does this accessory require an electrical connection?
No. The deflectors are passive airflow components and do not require a separate electrical or refrigerant connection.
Can I install the deflectors myself?
The deflectors are part of a split wine cellar cooling-system installation. Their orientation and surrounding openings should be coordinated with the qualified HVAC-R technician installing the complete system.
Are dimensions or weight published for this kit?
The supplied product resources do not provide separate dimensions or weight for model 03-DEFLECTOR-KIT-LRG. Compatibility should be confirmed by the accessory model and Blow-Through evaporator size.
