WhisperKOOL 4000/8000 Hybrid Airflow Kit – 1 Duct Plenum & 1 Airflow Deflector

WhisperKOOL Blow-Through Accessory WhisperKOOL 4000/8000 Hybrid Airflow Kit – 1 Duct Plenum & 1 Airflow Deflector Important Note: This Add-on Accessory cannot be purchase without the Main Unit. The WhisperKOOL 4000/8000 Hybrid Airflow Kit, model 03-HYBRID-KIT-LRG, is an airflow configuration accessory designed for compatible WhisperKOOL Blow-Through 4000 and Blow-Through 8000 evaporators. The kit includes one duct plenum and one airflow deflector, allowing one side of the evaporator to connect to ductwork while the opposite side exchanges air directly with the wine cellar. This hybrid configuration provides additional installation flexibility when a fully ducted or fully ductless arrangement is not practical. Choose this kit when only one airflow path—either the conditioned-air supply or cellar-air return—requires ductwork, while the opposite side can communicate directly with the wine cellar through an approved opening. 1 + 1 Plenum and deflector 4000 / 8000 Compatible evaporators Hybrid One ducted airflow path Accessory only: This kit does not include the Blow-Through evaporator, condensing unit, ductwork, refrigerant piping, thermostat, electrical work, registers, installation materials, or professional installation. Accessory Summary Quick Answer The 03-HYBRID-KIT-LRG converts a compatible WhisperKOOL Blow-Through 4000 or 8000 evaporator into a hybrid airflow configuration by combining one duct plenum with one airflow deflector. At a Glance Product at a Glance Product type Hybrid airflow configuration kit Model number 03-HYBRID-KIT-LRG Included components 1 duct plenum and 1 airflow deflector Airflow configuration Hybrid (one ducted path and one direct airflow path) Primary compatibility WhisperKOOL Blow-Through 4000 and Blow-Through 8000 evaporators Ductwork required Required on one airflow path only Cooling system included No Electrical connection required No Key Benefits Key Features Hybrid Airflow Configuration Combines one duct plenum and one airflow deflector, allowing a compatible Blow-Through evaporator to operate with one ducted airflow path and one direct airflow path. Flexible Installation Options Ideal for projects where only the supply or return side must be ducted due to architectural, structural, or mechanical constraints. Designed for Larger Blow-Through Models Model 03-HYBRID-KIT-LRG is intended for compatible Blow-Through 4000 and Blow-Through 8000 evaporators and should not be substituted for the smaller Hybrid Kit used with the Blow-Through Mini. Supports Concealed Installations The hybrid configuration allows the evaporator to remain hidden while simplifying ductwork requirements by ducting only one airflow path. Passive Airflow Accessory The plenum and deflector are passive airflow components that require no electrical wiring, refrigerant connections, or programming. Best Applications Best Applications Wine walls with limited duct routing options Custom cabinetry installations Soffit-mounted evaporators Mechanical rooms adjacent to the cellar Glass wine displays Architectural layouts with one restricted airflow path Projects requiring partial ductwork Custom residential and commercial wine cellar installations How It Works How the Hybrid Configuration Works The Hybrid Airflow Kit combines two airflow methods: Duct Plenum: Connects one side of the evaporator to insulated ductwork. Airflow Deflector: Directs airflow on the opposite side directly between the evaporator and wine cellar. Depending on the approved Blow-Through configuration, either the supply or return side may use the duct plenum while the opposite side uses the airflow deflector. The configuration should be selected before the evaporator is installed. Configuration Comparison Compare the Available Airflow Kits Configuration Included Components Typical Application Ducted 2 Duct Plenums Both supply and return airflow use ductwork. Ductless 2 Airflow Deflectors Both airflow paths communicate directly with the cellar. Hybrid 1 Duct Plenum + 1 Airflow Deflector One airflow path is ducted while the other is direct. Compatibility Compatibility The 03-HYBRID-KIT-LRG is designed for compatible: WhisperKOOL Blow-Through 4000 evaporators WhisperKOOL Blow-Through 8000 evaporators Compatibility should always be confirmed using the current WhisperKOOL configuration documentation before ordering. Package Contents What's Included 1 Large Duct Plenum 1 Large Airflow Deflector Sold Separately Not Included Blow-Through evaporator Condensing unit Ductwork Duct insulation Registers or louvers Refrigerant line set Thermostat Electrical wiring Installation materials Professional installation Installation Planning Installation Considerations Select the desired airflow orientation before mounting the evaporator. Use properly insulated ductwork on the ducted airflow path. Keep duct runs as short and direct as practical. Do not restrict the direct airflow opening used with the deflector. Maintain adequate service access around the evaporator. Coordinate airflow design with the installing HVAC-R professional. Airflow Requirements Register and Airflow Guidelines Decorative registers, grilles, and louvers should provide approximately 50%–65% open free area to maintain proper airflow. Restrictive airflow components can reduce cooling performance, increase operating noise, contribute to evaporator icing, and reduce overall system efficiency.

Selection Guidance Is This the Correct Airflow Kit? Choose the Hybrid Airflow Kit if: Your installation uses a compatible Blow-Through 4000 or 8000 evaporator. Only one airflow path requires ductwork. The opposite airflow path can communicate directly with the wine cellar. You need greater installation flexibility than a fully ducted or ductless configuration provides. Official Documentation Product Documents Blow-Through Configuration Sheet Blow-Through Product Sheet Register & Louver Airflow Requirements Linear Register Ducting Best Practices Common Questions Frequently Asked Questions What is the Hybrid Airflow Kit? It is an airflow accessory that combines one duct plenum and one airflow deflector for compatible Blow-Through 4000 and 8000 evaporators. What is included? One duct plenum and one airflow deflector. Which systems is it compatible with? Compatible WhisperKOOL Blow-Through 4000 and Blow-Through 8000 evaporators. Does this kit include the cooling system? No. This accessory is sold separately from the evaporator, condenser, and other cooling system components. When should I choose the Hybrid Kit? Choose it when only one airflow path requires ductwork while the opposite side exchanges air directly with the wine cellar. Can I use this with the Blow-Through Mini? No. The Blow-Through Mini requires its own dedicated Hybrid Airflow Kit. Does the kit require electrical power? No. The airflow components are passive accessories and do not require electricity. Can decorative registers be installed? Yes, provided they maintain adequate free airflow in accordance with WhisperKOOL guidance. Should installation be completed by an HVAC-R professional? Yes. The airflow configuration should be coordinated with the qualified technician installing the complete WhisperKOOL split cooling system.
