Exhaust Fans — selection guide

Exhaust Fans: 13 models, maximum airflow 216–216 m³/h, AC and DC motors, across 2 series.

Floor dryer blowers and cordless handheld blowers: the LWF line (LWF-100 to LWF-3200, 100–3,200 W on 220 V, 3-speed switch) dries floors and carpets after cleaning or water damage, and the LWHB 21 V battery blowers (450 W, 3.0 Ah) blow off dust and water on site without a mains lead.

How to select from this range

  1. Pick the floor dryer by the area to dry and the time available; the 1,000 W class is the everyday cleaning-contractor size, 3,200 W for large halls and water-damage jobs.
  2. For cordless work, check run time per charge (LWHB-02: 3.0 Ah battery, 3 h charge) against the job length.

Where these fans are used

  • Floor and carpet drying
  • Water-damage restoration
  • Cleaning contractors, hotels, offices and shopping malls

Curves in the selector are digitised from each model’s published catalogue curve; wind-tunnel measured curves (AMCA 210 / ISO 5801 methods) are labelled “measured” where available — see the test labs and certificates. Final selection is confirmed at the duty point and by project validation.

FAQ — Exhaust Fans
