AC Cross Flow Fans

AC Cross Flow Fans — selection guide

AC Cross Flow Fans: 128 models, impellers Ø30–150 mm, maximum airflow 23–4,000 m³/h, static pressure to 255 Pa, AC motors, across 92 series.

AC cross flow fans (LWCA) run on 230 V or 115 V mains with shaded-pole or capacitor motors, Ø30 to Ø150 mm and lengths from 90 to 1,200 mm. The Ø30–50 mm sizes (87 models) are the appliance fans — fireplaces, ovens, small heaters, elevator cabins; the Ø60–150 mm sizes (41 models) serve indoor air-conditioner units, air curtains and larger cabinets. All impellers are aluminium alloy on maintenance-free ball bearings.

How to select from this range

1. Take the impeller length from the housing opening and the diameter from the housing depth; then compare speeds within that size.
2. Specify 115 V for North American appliances, 230 V for Europe; both are catalogued for the compact sizes.
3. Tapped windings give two or three speeds without electronics.
