FAQ

What should I check before using LONGWELL LWBE3G225 in place of ebm-papst R3G225?
The impeller diameter is the same. Confirm the mounting hole pattern, inlet ring diameter and shaft height against the dimensioned drawing on the LONGWELL LWBE3G225 model page before ordering; the available control inputs (0–10 V / PWM / Modbus RTU) and voltages are listed in the table above.
Where can I find efficiency data for LWBE3G225?
LONGWELL does not publish a single peak-efficiency figure for the LWBE3G225. The model page on the selection site gives airflow, static pressure and input power along the curve (measured where marked, nameplate-estimated otherwise), so the efficiency at your duty point follows directly; a test report for a specific model is available from engineering on request.
What is the LONGWELL lead time?
LONGWELL LWBE3G225 ships in 15–30 days for orders up to 500 units and 6–10 weeks for 1,000+ unit OEM programs. Sample units ship in 1–3 days from stocked Ø225 mm inventory.
How is LONGWELL pricing determined?
LONGWELL quotes per project. Pricing depends on quantity, voltage, IP rating, and control protocol options.
What applications is LWBE3G225 typically used for?
LWBE3G225 is typically specified for Hydronic fan coil unit, small AHU, DCFC compact cabinet. Particularly suited for hydronic fan coil indoor and DCFC compact cabinet ventilation.
