APPLICATIONS

These small centrifugal fans are suitable for conveying clean air and dust-free fumes, up to a maximum temperature of 80 °C*.

They are used in all industrial applications that need small volumes of air at medium-high pressure – for example machine tools, extraction from or supply to ducts, aspirators etc.

DESIGN

Housing in painted steel. Single-inlet impeller in galvanised sheet with forward-curved blades. Asynchronous three-phase or single-phase motor, protection IP 55, insulation class F, efficiency 2, S2 duty, form B35 (FORWARD 122-142 form B5), built to IEC / EEC (UNEL MEC) standards, version 5; directly coupled, impeller rotation LG270.
