Why Engineers Switch from ZAvblue 800 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 Ziehl-Abegg ZAvblue 800 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 Ziehl-Abegg ZAvblue 800. LONGWELL supplies its Modbus RTU register map with the fan so the BMS points can be re-mapped; the register addresses are not identical to the Ziehl-Abegg map.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.
