Product Details
- Sukup Axial Fans give the highest airflow for the money!
- 3500 RPM motors used in Sukup Axial Fans have been specially-engineered for Sukup’s high-performance blades.
- Square end plates give uniform support all around the housing while eliminating legs that concentrate stress and distort the housing. Square housings also maintain the accurate roundness of the housings, allowing for close fan blade tip clearance.
- Close tip clearance increases airflow by preventing air from blowing back through the area between the blade and housing.
- Fan blades are precision-balanced for vibration–free operation
- Blades are secured to the motor shaft with Trantorque bushings to ensure the most secure attachment, as well as serviceability.
- Galvanized housings resist rust and look good for years to come.
- Two-year limited warranty
