FAQ

What should I check before using LONGWELL LWAE3G450 in place of ebm-papst W3G450?
The impeller diameter is the same. Confirm the mounting hole pattern, inlet ring diameter and shaft height against the dimensioned drawing on the LONGWELL LWAE3G450 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 LWAE3G450?
LONGWELL does not publish a single peak-efficiency figure for the LWAE3G450. 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 LWAE3G450 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 Ø450 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 LWAE3G450 typically used for?
LWAE3G450 is typically specified for Commercial outdoor condenser, large rooftop AHU, industrial cooling tower. Particularly suited for commercial rooftop AHU and industrial cooling tower ventilation.
