Medium Pressure Backward Curved Centrifugal Fans

Axair’s supply partner, Casals, has developed a range of powerful medium pressure backward curved centrifugal fans for universal use in medium pressure applications.

NIMUS / NIMAX Range

With air flows of up to 88,000m³ per hour, NIMUS and NIMAX fans offer the most complete range on the market. There are almost 100 standard types available with impeller sizes between 311mm and 1402mm. Motor sizes range from 0.37kW to 110kW with 2, 4, 6 and 8 pole options available. This allows the range to provide solutions for a wide scope of air flow and pressure requirements.

The NIMUS and NIMAX ranges are available in an ATEX certified version on request. (Read our guide to ATEX fans here.)
