Commercial Square Wall-Type Axial Fans
AS-EXT-AF axial fans combine a square casing with sheet steel blades and are used for commercial and industrial ventilation. They are designed for easy wall or window mounting and provide high airflow with a durable construction.
The square casing is made of galvanized sheet steel with an electrostatic powder coating and a rectangular connection profile. Air discharge can be horizontal or vertical. The direct-driven sheet steel impellers, balanced to ISO 1940-1, cover sizes from Ø200 to Ø350 mm.
The direct-drive, 2-pole external-rotor motors run on a 230 V single-phase supply, with IP44 protection and class F insulation, rated for S1 and S2 duty. 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.
