Industrial centrifugal blower for HVAC
The Fans RF22P-2DN.B4.5R is a new centrifugal blower built on the 1PH7912 series platform from ZIEHL-ABEGG. It serves engineers and maintenance teams who need reliable air movement for refrigeration, air conditioning, medical equipment, rail vehicles, industrial cleaning, electronic enclosures, new energy vehicles and supermarket systems.
Air volume adjustable across a 2000 to 13000 m3/h
The FB series design uses four aluminium blades with diameters from 350 to 630 mm and offers three blade-angle options. Both supply directions are available and speed is 100 % adjustable, so the blower can be matched to the exact airflow demand of the application without oversizing.
Replaces fixed-speed or single-angle blowers
The jump is worth it when a system requires variable airflow across multiple operating points or when blade-angle flexibility simplifies spare-part stocking. Buyers who need a different mounting footprint, a specific motor voltage not listed here, or a non-centrifugal airflow pattern should look elsewhere.
