Why Engineers Switch from R3G225 to LWBE3G225
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 LWBE3G225 matches the ebm-papst R3G225 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 LWBE3G225 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst R3G225. 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.
Typical Applications
The LWBE3G225 is widely deployed across Hydronic fan coil unit, small AHU, DCFC compact cabinet. Common application categories include:
- Hydronic FCU
- Small AHU
- DCFC compact
Particularly suited for hydronic fan coil indoor and DCFC compact cabinet ventilation.
