Exhaust Fans
Exhaust and ventilation fans for bathrooms, kitchens, workshops and basements, including floor dryers and solar roof fans. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.
Exhaust Fans — selection guide
Exhaust Fans: 13 models, impellers Ø29–50 mm, maximum airflow 216–61,200 m³/h, AC motors, across 2 series.
Exhaust and ventilation fans for buildings and workshops: LWHB floor dryers and the LWF-1000 / LWF-3200 industrial exhaust fans, 216 to 61,200 m³/h with 100–3,200 W motors on 220 V, for wall, window or roof mounting.
How to select from this range
- Size by room volume and air-change rate; add resistance for louvres and ducts.
- Choose shutter type and IP rating for outdoor or wet locations.
Where these fans are used
- Bathrooms and kitchens
- Workshops and garages
- Warehouses and basements
Every figure above is measured on our own test rigs per AMCA 210 / ISO 5801 methods — see the test labs and certificates. Final selection is confirmed at the duty point and by project validation.
FAQ — Exhaust Fans
How do I size an exhaust fan?
Multiply room volume by the required air changes per hour to get airflow, then choose a model whose curve covers that airflow at the louvre resistance.
