This Air-Pro by VMI exterior blower motor moves 409 CFM through an 8-inch duct connection and mounts flat on the exterior wall or roof, keeping the motor outside the living space where noise and heat are not a concern.
Most range hood installations house the blower inside the hood body or in a power pack that sits above the cooktop. An exterior blower takes a different approach: the motor mounts at the terminus of the duct run, on the outside of the building, and pulls air through the duct from the outside end. The result is that the motor's sound and vibration stay outside, and the duct itself acts as a sound buffer between the blower and the kitchen. For open-plan kitchens, great rooms, or spaces where noise levels matter, this configuration is a meaningful upgrade over an in-line or in-hood motor setup. At 409 CFM, the unit supports a meaningful exhaust rate across the duct run, accounting for the friction loss that longer or more complex duct paths introduce.
The 8-inch duct connection is larger than the 6-inch diameter common on lower-output units, and that extra cross-section reduces static pressure in the duct, which helps the blower maintain usable airflow across longer runs or duct paths with turns. The flat-mount profile keeps the blower tight to the exterior surface rather than projecting on a raised bracket, which matters in applications where clearance at the eave, soffit, or wall cap is limited. Duct termination hardware and wall or roof caps are matched to the 8-inch opening and selected separately to suit the installation location.
This unit is the right choice when the hood installation calls for a remote motor rather than a self-contained power pack inside the hood. It suits kitchens where a quieter cooking environment is a design goal, where a long duct run demands a motor positioned closer to the exit point, or where the hood shell and liner are already specified and the blower is the final piece of the ventilation system. Confirm that the duct path, the hood liner, and the wall or roof penetration are all sized for 8-inch duct before finalizing the installation plan.
It mounts flat on the exterior of the building, at the end of the duct run, rather than inside the hood body or in the ceiling. This positions the motor outside the living space.
An exterior blower keeps the motor and its noise outside the structure. For open kitchens or quiet-cooking environments, the difference in perceived noise at the cooktop is significant compared to an in-hood or in-line motor.
No. The duct termination cap and any wall or roof penetration hardware are selected separately to match the installation location and the 8-inch duct size.
This is a remote blower motor that connects via ductwork. It is not hood-model-specific the way an in-hood power pack is, but the hood liner and duct path must be sized to work with an 8-inch duct and a remotely mounted blower. Confirm compatibility with the hood and liner before ordering.
For installations where ventilation performance and a quieter kitchen environment both matter, this exterior flat-mount blower puts 409 CFM of exhaust capacity exactly where it belongs: outside the home.
