Product Applications

Centrifugal fans should be applied to push aeration systems.
1750 RPM centrifugal fans should be considered when greater air volumes are required at higher static pressure. The fan should be selected to operate at optimum efficiency. Optimum efficiency is considered midrange of the published fan performance.
3500 RPM centrifugal fans should be considered when low air volumes are required at high static pressures. The fan should be selected to operate at optimum efficiency. Optimum efficiency is considered midrange of the published fan performance.
