ebm-papst W3G800 Alternative — LONGWELL LWAE3G800
Looking for an alternative for ebm-papst W3G800-GD24-50? The LONGWELL LWAE3G800 is the same-size alternative — same control protocol, mounting dimensions on the LONGWELL drawing, performance characterized using AMCA 210/211 test methods (test report on request) — at 40–55% lower landed cost with 15–30 day delivery vs 16–22 weeks ex-works ebm-papst. Widely deployed across Large dry cooler, cooling tower, large RTU. Particularly suited for large dry coolers and free-cooling coil installations for hyperscale data centers.

Why Engineers Switch from W3G800 to LWAE3G800
4–8× Faster Delivery
40–55% Lower Landed Cost
Drop-in Candidate · Same Size Class
Drop-in compatibility: what matches and what to confirm
Mechanical match
The LONGWELL LWAE3G800 matches the ebm-papst W3G800 mounting pattern (M-mount, ISO 9001 plenum-fan footprint) per the mounting dimensions on the LONGWELL drawing. Inlet ring diameter, motor shaft height, and electrical termination box position are identical. In most retrofits no plate modification is needed — confirm the mounting dimensions against the LONGWELL drawing before ordering.
Electrical & control match
The LWAE3G800 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst W3G800. LONGWELL provides the Modbus register map and a cross-reference to the ebm-papst map for BMS integration. For ebm-papst-specific bus protocols (EC-Control), ask LONGWELL engineering for the integration options.
Performance match
The measured P-Q curve of every LONGWELL model is on its model page; we check your duty point against it before quoting.
