Production Lead Time

15–30 days
Ex works for production batches. Stock standard models ship as samples in 1–3 days.

Pricing

Price depends on model, voltage, control option and quantity. Sample fees are credited in full against the first production order.

Nearest size + FanGrid option

Ø155 mm
nearest listed size with the same 0–10 V / PWM / Modbus RTU control; mounting per the LONGWELL drawing (not a drop-in for Ø160 mm).

Installation and control: what to check

Mechanical

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

The LONGWELL LWBE3G155 accepts a 0–10 V analog speed reference, PWM and Modbus RTU (RS485) control signals (per model; see the model datasheet). LONGWELL supplies its Modbus register map for BMS integration.For other bus protocols, ask LONGWELL engineering for the integration options.

Performance

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 typically specified for 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.

FAQ

What should I check before using LONGWELL LWBE3G155 in place of ebm-papst R3G160 PHI?
Not as a drop-in: LONGWELL does not list a Ø160 mm model in this family. The nearest listed size is Ø155 mm (LWBE3G155); for equal airflow we propose a FanGrid array of smaller EC units or a custom development. Ask engineering with your duty point.
Where can I find efficiency data for LWBE3G155?
LONGWELL does not publish a single peak-efficiency figure for the LWBE3G155. The model page on the selection site gives airflow, static pressure and input power along the curve (measured where marked, nameplate-estimated otherwise), so the efficiency at your duty point follows directly; a test report for a specific model is available from engineering on request.
What is the LONGWELL lead time?
LONGWELL LWBE3G155 ships in 15–30 days for orders up to 500 units and 6–10 weeks for 1,000+ unit OEM programs. Sample units ship in 1–3 days from stocked Ø160 mm inventory.
How is LONGWELL pricing determined?
LONGWELL quotes per project. Pricing depends on quantity, voltage, IP rating, and control protocol options.
What applications is LWBE3G155 typically used for?
LWBE3G155 is typically specified for Passivhaus single-family ERV, KfW 40 / 55 EU residential, premium MVHR. Particularly suited for EU Passivhaus and KfW certified residential ERV/MVHR units.
