Why Engineers Switch from San Ace EC Turbo to LWBE3G280
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 LWBE3G280 matches the Sanyo Denki San Ace EC Turbo 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 LWBE3G280 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as Sanyo Denki San Ace EC Turbo. 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 Sanyo Denki 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.
Typical Applications
The LWBE3G280 is widely deployed across Japan-domestic fab FFU, JIS-spec cleanroom. Common application categories include:
- Japan fab FFU
- Cleanroom
- Sub-fab return
Particularly suited for Japan domestic fab fit-out and JIS-spec cleanroom.
