Flange Adapter for Dayton Blower 1TDR3


  • This centrifugal blower flange adapter was created by Vent Works to provide an easy way to exhaust the Dayton Blower 1TDR3. This adapter transitions from the odd-sized rectangular exhaust outlet on the blower to a standard 4 inch circular duct and can be used with rigid, semi-rigid or flexible duct. This adapter is made using galvanized steel and is manufactured here in the USA.

    This adapter also fits the following centrifugal blowers:
    Dayton 1TDR3, Dayton 6FHX9, Dayton 4C447, Dayton 70633277, Fasco B45227, Fasco 7063-3277, AO Smith 459A, 7073-0107

    Warning: This adapter may not fit other blowers because flange sizes and bolt patterns vary greatly. 

    Note: This is a flat version, it will sit flush against the Dayton Blower right out of the box. If you need an adapter for the spray booth we designed see our DIY Hobby Spray Booth Square To Round Adapter.
