Plastic Inline Duct Fans — selection guide
Plastic Inline Duct Fans: 24 models, impellers Ø98–315 mm, maximum airflow 205–2,500 m³/h, static pressure to 721 Pa, AC and EC motors, across 9 series. 18 of them carry a measured P-Q curve and 24 a dimensional drawing.
Plastic-cased inline duct fans are the light, economical fans for residential fresh-air and exhaust systems: Ø100 to Ø315 mm, 205–2,500 m³/h at 135–721 Pa, 25–320 W. LWDA models on 230 V and 115 V and the LWDE3G EC models (Ø100 / 150 / 200) on a 110–240 V universal input. Corrosion-free casing, quick-release motor plate on most sizes.
How to select from this range
- Match the duct size, then check the duty point against the filter and grille resistance of a residential run.
- Choose LWDE3G for demand-controlled ventilation on any mains voltage.
- For higher pressure or warm air move to the metal-cased line.
Where these fans are used
- Residential fresh-air systems
- Bathroom and kitchen exhaust
- Small offices and shops
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.
