Why Engineers Switch from K3G560 to LWBE3G560

4–8× Faster Delivery

15–30 days
vs 14–22 weeks ex-works for ebm-papst in 2026. Sample units 1–3 days from stock vs 4–10 weeks.

40–55% Lower Landed Cost

−€600 to −€2,400
per unit at equivalent spec, depending on size and quantity. On a 50-unit FanGrid retrofit, typical CapEx delta is €30k–€120k.

Drop-in Candidate · Same Size Class

Ø560 mm
Same impeller size and control protocol; confirm the mounting hole pattern and inlet ring against the LONGWELL drawing before ordering.

Drop-in compatibility: what matches and what to confirm

Mechanical match

The LONGWELL LWBE3G560 matches the ebm-papst K3G560 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 LWBE3G560 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst K3G560. 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 LWBE3G560 is widely deployed across Large industrial AHU, hyperscale CRAH FanGrid, BESS large-cabinet. Common application categories include:

  • Industrial AHU
  • Large CRAH FanGrid
  • Large process AHU

Particularly suited for hyperscale CRAH FanGrid 6×6 and 9-fan array configurations.

FAQ

Is LONGWELL LWBE3G560 a true drop-in replacement for ebm-papst K3G560?
Same size class and control interface. Confirm the mounting hole pattern, inlet ring diameter and shaft height against the dimensioned drawing on the LONGWELL LWBE3G560 model page before ordering; it accepts the same 0–10 V analog / PWM / Modbus RTU control signals and is offered in the voltages listed in the table above.
How does LWBE3G560 compare on efficiency to K3G560?
LONGWELL does not publish a single peak-efficiency figure for the LWBE3G560. 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's the 2026 lead time difference?
As of May 2026: ebm-papst K3G560 requires 14–22 weeks ex-works due to ongoing allocation. LONGWELL LWBE3G560 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 Ø560 mm inventory.
What's the cost delta?
At equivalent specification (same Ø, same airflow/Pa, same IP, same control), LONGWELL LWBE3G560 typically lands at 40–55% below ebm-papst K3G560 ex-works pricing. Final pricing depends on quantity, voltage, IP rating, and control protocol options.
What applications is LWBE3G560 typically used for?
LWBE3G560 is widely deployed across Large industrial AHU, hyperscale CRAH FanGrid, BESS large-cabinet. Particularly suited for hyperscale CRAH FanGrid 6×6 and 9-fan array configurations.
