Tubular Inline Centrifugal Fan


The TSL Tubular Inline Centrifugal Fan offers the reliable performance of a centrifugal fan with the space saving advantages of an axial-type fan. The TSL employs a specially designed non-overloading airfoil wheel, resulting in quieter operation for supply and exhaust where space is limited. In a tubular centrifugal fan, the air turns 90° after leaving the wheel. Twin City Fan & Blower’s unique wheel design with open back plate (patent #5,171,128) allows this turn to be made with a minimum of turbulence and loss.
