Why Engineers Switch from K3G220 to LWBE3G220
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 LWBE3G220 matches the ebm-papst K3G220 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 LWBE3G220 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst K3G220. 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 LWBE3G220 is widely deployed across Small commercial AHU, residential heat pump indoor, fan coil. Common application categories include:
- Small AHU
- Fan coil
- Heat pump indoor
- Range hood premium
Particularly suited for residential heat pump indoor fan coil and premium range hood retrofit.
