AS-BLOW

AS-BLOW in-duct axial fans are in-line fans mounted in round ventilation ducts. Depending on the installation method, they operate in exhaust or supply mode. When used with DSKP line holders, the fans can be mounted between two plastic ducts. They have a round duct connection and are available in Ø100, Ø125 and Ø150 mm sizes, with a plastic impeller; air discharge can be horizontal or vertical. The direct-drive fans use 2-pole synchronous motors with class F insulation and IP44 protection, totally enclosed fan-cooled (TEFC) and rated for S1 and S2 duty. Supply is 230 V single-phase; versions for 50 Hz and 60 Hz are available. The motors are outside the scope of IE efficiency classification. Operating air temperature: −20 °C to +40 °C. Standard: IEC CB 60335-2-80.
