The LONGWELL LWBE3G-710-EC matches the ebm-papst K3G710 mounting pattern (M-mount, ISO 9001 plenum-fan footprint) within ±0.5 mm tolerance. Inlet ring diameter, motor shaft height, and electrical termination box position are identical. Drop-in retrofit requires no AHU rework, no plate modification, and no plenum hole resizing.
The LWBE3G-710-EC accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst K3G710. Default Modbus register map is compatible with the ebm-papst ecosystem; LONGWELL provides a free Modbus map cross-reference for BMS integration. ebm-papst-specific proprietary protocols (EC-Control bus) are bridged via a free MODBUS gateway available from LONGWELL Engineering — no BMS reprogramming required.
The PQ curve of LONGWELL LWBE3G-710-EC sits within 2–3% of the ebm-papst K3G710 curve across the full operating envelope (verified by third-party AMCA 210/211 testing at TÜV and Intertek labs). Wire-to-air efficiency at BEP is 90% vs 91% for ebm-papst (1 pp delta at peak). In typical part-load HVAC duty, the gap narrows to within 1 pp.
The LWBE3G-710-EC is widely deployed across Very large CRAH, industrial process exhaust, stadium/atrium HVAC. Common application categories include:
Particularly suited for very large CRAH and industrial process exhaust applications.
