AS-RFL

Commercial Backward-Curved Scroll Fans

AS-RFL scroll fans can be used in all kinds of ventilation projects. They feature high-flow impeller blades, a durable casing and a discharge outlet whose direction can be changed. The scroll casing is made of galvanized sheet steel with an electrostatic powder coating, with round or rectangular connections. The fan can be installed in a cabinet or in-line, with horizontal or vertical air discharge. Backward-curved aluminium impellers, balanced to ISO 1940-1, cover sizes from Ø280 to Ø710 mm. The direct-drive, totally enclosed fan-cooled (TEFC) asynchronous motors are 4-pole WAT motors with IP55 protection and class F insulation, rated for S1 and S2 duty. IE3 efficiency is standard; IE4 and EC motors are available on request. Versions for 50 Hz and 60 Hz supplies are available. Operating air temperature: −20 °C to +50 °C. Standards: IEC 60335-2-80, ISO 1940-1.
