Impeller Ø178–254 mm — selection guide
Impeller Ø178–254 mm: 12 models, impellers Ø178–254 mm, maximum airflow 1,000–4,146 m³/h, static pressure to 608 Pa, EC and AC motors, across 1 series. 12 of them carry a P-Q curve and 12 a dimensional drawing.
The compact commercial blowers — Ø178 to Ø254 mm — are the units in kitchen hoods, small ventilation boxes and ovens: LWFA-E-200 / 225 / 250 AC direct-drive blowers and the LWDD7 / 8 / 9 / 10 EC blowers, 1,000–4,146 m³/h at 215–608 Pa, on 220 V. Eight of the twelve models are EC with 0–10 V speed control.
How to select from this range
- Rate on total pressure at the outlet flange, including hood filters.
- Choose EC for hoods with variable extraction, AC for fixed duty.
Where these fans are used
- Kitchen extraction hoods
- Compact ventilation boxes
- Ovens and warming cabinets
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.
