For new installations or replacement, Grainger has many of the blower accessories you need to get your ventilation system up and running. We have direct drive blower wheels that help move forced heated, cooled, or ambient temperature air to specific spot areas. Applications include ventilation, air conditioning, heating and dehumidifying in industrial and commercial applications. You’ll find a large selection of blower accessories such as inlet and outlet guards, insulated fan covers, extension ducts, hub pullers, capacitor covers, inflatable tubes and more. Blower supports allow you to stabilize HVAC blower fans and can be used with your double inlet forward curved direct drive blowers. Heat slingers mount on the blower shaft between the housing and bearing to cool the bearing and allow specified blowers to handle air inlet temperatures up to 450°F.Close
