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

  1. Match the duct size, then check the duty point against the filter and grille resistance of a residential run.
  2. Choose LWDE3G for demand-controlled ventilation on any mains voltage.
  3. 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.
