Centrifugal Fans

Fans
Gasho offers a comprehensive selection of Howden American centrifugal fans for a wide range of applications. These centrifugal fans feature the design advantage of Howden American’s years of expertise, experience, computer simulation, developments from Airbus design, and customer input.

The Gasho selection of Howden American centrifugal fans includes fans for general air movement, emergency smoke extraction, as well as ATEX explosive atmospheres in the UK. One piece outlet flanges with mounting holes and continuous weld are standard on these centrifugal fans. Design features include eccentric or spring lock bearings for positive bearing to shaft locking.

Considered to be the most widely used type of fan used in the HVAC industry, centrifugal fans are typically less expensive than axial fans and simpler in construction. Centrifugal fans are well-suited for transporting gas or materials and for facility ventilation systems. They’re also an ideal choice for industrial processes and air pollution control systems.
