Why Engineers Switch from R3G160 PHI to LWBE3G155
4–8× Faster Delivery
40–55% Lower Landed Cost
Nearest size + FanGrid option
Drop-in compatibility: what matches and what to confirm
Mechanical match
LONGWELL does not currently list a Ø160 mm unit in this family. The nearest listed size is Ø155 mm (LWBE3G155); for the airflow of a single Ø160 mm fan, engineering proposes 2–4 smaller EC units in a FanGrid array or a custom development — mounting is not a drop-in.
Electrical & control match
The LWBE3G155 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst R3G160 PHI. 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 LWBE3G155 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.
