Air-Pro roof mounted external blower is a roof-mounted external ventilator designed to move range hood exhaust out of the kitchen area and onto the roof line. This VMI, Inc. unit is part of the Air-Pro exterior blower motors line, so it is intended to work as the remote blower in a range hood system rather than a self-contained hood. The blower mounts on the roof and uses an 8-foot duct run, which routes air from the hood to the exterior so cooking fumes discharge away from cabinets. A 409 CFM rating on this exterior fan defines the airflow it can pull through the duct, which helps plan hood sizing for typical residential cooking loads. A galvanized steel housing with a grey finish forms the outer body, which provides a rigid shell around the fan for rooftop use.
This roof mounted external blower is specified for pitched or flat roofs using either a flat or raised panel, which lets installers match the panel style to the roof slope for a stable mount. The unit is 100 percent speed controllable, so it can be paired with a compatible control to vary airflow from low to high and tune draw strength for different cooking tasks. An 8-foot duct run is part of the design, setting the distance between the hood connection and blower so routing can be laid out early in the project. The blower housing is built from galvanized steel, which provides a solid mounting base when fastening to roof framing around the roof opening.
This VMI, Inc. 5070 unit sits in the Range Hood Accessories and Ductwork Kits class, so it functions as an external blower in a range hood ventilation system. It is described as a roof mounted external blower for pitched or flat roofs, which positions it at the roof level above the kitchen rather than in the cabinet or wall. The blower is suitable for airstream temperatures up to 140 degrees, meaning it is built to handle warm cooking exhaust as it exits the hood and travels through the 8-foot duct. A 409 CFM airflow rating defines its ventilation capacity, which supports typical residential cooking ventilation needs where a roof discharge is preferred. Heat dissipation features support long motor life, which keeps the blower working as part of the overall hood system over repeated cooking cycles.
The 100 percent speed controllable design lets installers and users pair this blower with variable-speed controls so airflow can be adjusted to match light simmering or heavier frying, which helps balance capture performance and sound level at the hood. The galvanized steel housing provides structural strength around the fan and motor, which supports a secure mount on pitched or flat roofs and keeps the unit stable when the fan is running. A grey finish on the housing offers a neutral exterior appearance, which helps the roof-mounted blower blend with common roof components in visible locations. Built-in thermal overload protection with automatic reset guards the motor from temperature spikes in the airstream or from continuous operation, which supports dependable function without manual reset work. Heat dissipation design assists long motor life, helping the system maintain airflow performance over time in a standard kitchen ventilation setup.
The Air-Pro roof mounted external blower is designed for roof mounting on pitched or flat roofs, so the fan sits outside while ductwork connects it to the interior range hood.
The VMI 5070 exterior fan is rated at 409 CFM, which sets its exhaust capacity and helps match the blower to the hood size and cooking intensity on the project.
The 8-foot duct detail defines the intended distance between hood and blower, so installers can design framing penetrations and routing within that run length.
This roof mounted external blower is suitable for airstream temperatures up to 140 degrees, so it handles typical warm cooking exhaust in residential kitchens.
The built-in thermal overload protection with automatic reset helps protect the motor from overheating, supporting continued operation after high-heat or long-use periods.
The Air-Pro exterior blower motor is 100 percent speed controllable, so compatible controls can vary airflow to match light or heavy cooking demands.
The Air-Pro roof mounted external blower from VMI, Inc. combines galvanized steel housing, 409 CFM performance, and suitability for pitched or flat roofs, giving you a defined solution for routing cooking exhaust to the roof line through an 8-foot duct run.
