Description
LWBE3G355-102PS-16 — EC Backward-Curved Centrifugal Fan
The LONGWELL LWBE3G355-102PS-16 is a backward-curved centrifugal fan driven by an EC external-rotor motor. Decoded from the LONGWELL type code: Ø355 mm impeller, Ø102 mm motor rotor, with bracket, supply 230 VAC, three-phase winding, series number 16.
EC backward-curved fans are the standard choice for AHU, FCU, FFU, air purifiers, sterilisation and humidifier equipment, EC fan grids (fan walls) and data-centre cooling — speed is set steplessly by a 0–10 VDC or PWM signal, so the fan runs only as hard as the duty requires.

Performance data
Air volume, static pressure, input power and sound level for LWBE3G355-102PS-16 depend on the operating point you set through the 0–10 VDC / PWM input. Send us your required airflow and static pressure and our engineers will return the full duty point, the measured sound level and a dimensional drawing for this model — normally within one working day.
Typical applications
AHU (air handling units) · FCU (fan coil units) · FFU (fan filter units) · air purifiers · sterilisation equipment · humidifier equipment · EC fan grid / fan wall · ventilation units · data-centre cooling.
