Why Engineers Switch from R3G160 PHI to LWBE3G-160-PHI-EC
4–8× Faster Delivery
40–55% Lower Landed Cost
True Drop-In Compatibility
Drop-In Compatibility Details
Mechanical match
The LONGWELL LWBE3G-160-PHI-EC matches the ebm-papst R3G160 PHI 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.
Electrical & control match
The LWBE3G-160-PHI-EC accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst R3G160 PHI. 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 / ZA-control) are bridged via a free MODBUS gateway available from LONGWELL Engineering — no BMS reprogramming required.
Performance match
The PQ curve of LONGWELL LWBE3G-160-PHI-EC sits within 2–3% of the ebm-papst R3G160 PHI 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 68% vs 72% for ebm-papst (4 pp delta at peak). In typical part-load HVAC duty, the gap narrows to within 1 pp.
Typical Applications
The LWBE3G-160-PHI-EC is widely deployed across Passivhaus single-family ERV, KfW 40 / 55 EU residential, premium MVHR. Common application categories include:
- Passivhaus single-family ERV
- KfW 40 build
- Premium MVHR
Particularly suited for EU Passivhaus and KfW certified residential ERV/MVHR units.
