High-pressure air supply fans are designed to generate static pressures up to 10 kPa while supplying fresh or process air at flow rates from 5,000 to 200,000 CFM. They overcome long duct runs, filters, and heat-exchanger friction losses.
Backward-curved or radial impellers in split-casing housings provide efficient, balanced operation. IE4 motors and direct-drive configurations minimize energy loss.
Variable frequency drives (VFDs) enable pressure-based control, adjusting speed to maintain target supply pressure and prevent under- or over-pressurization.
Maintenance features include external lubrication ports, split-casing for impeller removal, and vibration monitoring. High-pressure air supply fans ensure reliable air delivery for ventilation and process applications.
