Wall-mounted axial fan for extraction from industrial, warehouse and commercial buildings, with a 450 mm diameter and a max airflow of 5200 m³/h at 250 W. The Harmann fan has a compact, flat motor-rotor design where the motor body takes up minimal space.

The housing is a square mounting plate in profiled steel sheet, painted black, with a powder-coated steel grille that carries the motor assembly with external rotor and the junction box. The fan is installed in building openings and only from the inside, from the room side.

What makes exhaust fan WAX-450-W-4-5100S a strong choice for industrial and premises ventilation?

It delivers 5200 m³/h max airflow and 125 Pa max pressure with a single-phase asynchronous motor at 230 V/50 Hz and 250 W. Noise level is 62 dB(A) at 3 m distance, weight 10 kg.

The rotor blades are black-painted steel, dynamically balanced to class G4 according to DIN ISO 1940. The motor has integrated thermal protection that cuts the power at approximately 150-160°C and resets at 90-120°C. Insulation class F (155) and speed control by voltage regulation are part of the design.
