Aerodynamically Designed Blades for Increased Air Volume Rates
ER & DR axial fans feature aerodynamically shaped blades designed to move large volumes of air. They can provide precise measures of increased airflow rates up to 33,000 m³/h and are available in impeller sizes 200mm up to 1000mm.
Pipe sleeve with double-sided standard flange for pipe installation.
ER range - single phase double flanged axial fans
DR range - three phase double flanged axial fans
General ventilation and extraction, fume extraction, ventilation for cooling; within factories, workshops, warehouses, and other commercial premises.
The high-performance axial fans have aerodynamically shaped blades:
Size from 200mm - 300mm are made from painted and galvanised steel.
Size from 315 - 630-6 are made from plastic.
Size from 630-4 to 1000 are made of die-cast aluminium.
Motors from size 200 to 300 offer IP44 protection.
Motors from Size 315 to 1000 offer IP54 protection.
Technical Data
The ER & DR range of short cased axial fans feature a space saving external rotor motor used with moisture protection. The motors with built-in ball bearings, are designed with thermal overload protection and available with an ingress protection rating of IP44 or IP54.
