CHF

Housed Centrifugal Fans,
High Pressure/High Volume

Application

The Model CHF fan from Aerovent is a high efficiency backward curved industrial fan designed for handling relatively clean air in high pressure applications. The single-thickness, dihedral backward curved blade on the impeller is designed to move air in a highly efficient manner. The airfoil blade is even more efficient than the backward curved blade and should target applications where power needs to be optimized and noise minimized. Typical industries include general HVAC (exhaust, filtration, return and supply, air of commercial buildings), automotive, air pollution, fertilizer, metal and mineral processing, pulp and paper, petrochemical, pharmaceutical, power, water and wastewater treatment.

The aerodynamically designed impeller and housing of the Model CHF fan produces a high volume of air at a lower velocity, eliminating the need for an expansion evasé.

Model CHF fans are available with a variety of construction options and accessories, offering the versatility and flexibility required in today’s commercial and industrial applications.
