Why Engineers Switch from K3G1000 to LWBE3G630

4–8× Faster Delivery

15–30 days
vs 18–24 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.

Nearest size + FanGrid option

Ø630 mm
nearest listed size with the same 0–10 V / PWM / Modbus RTU control; mounting per the LONGWELL drawing (not a drop-in for Ø1000 mm).

Drop-in compatibility: what matches and what to confirm

Mechanical match

LONGWELL does not currently list a Ø1000 mm unit in this family. The nearest listed size is Ø630 mm (LWBE3G630); for the airflow of a single Ø1000 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 LWBE3G630 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as ebm-papst K3G1000. 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 LWBE3G630 is widely deployed across Heavy mining ventilation, cement kiln induced-draft, steel sintering exhaust. Common application categories include:

  • Heavy mining
  • Cement induced draft
  • Steel sintering

Particularly suited for heavy mining ventilation and cement kiln induced-draft duty.

FAQ

Is LONGWELL LWBE3G630 a true drop-in replacement for ebm-papst K3G1000?
Not as a drop-in: LONGWELL does not list a Ø1000 mm model in this family. The nearest listed size is Ø630 mm (LWBE3G630); for equal airflow we propose a FanGrid array of smaller EC units or a custom development. Ask engineering with your duty point.
How does LWBE3G630 compare on efficiency to K3G1000?
LONGWELL does not publish a single peak-efficiency figure for the LWBE3G630. 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 K3G1000 requires 18–24 weeks ex-works due to ongoing allocation. LONGWELL LWBE3G630 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 Ø1000 mm inventory.
What's the cost delta?
At equivalent specification (same Ø, same airflow/Pa, same IP, same control), LONGWELL LWBE3G630 typically lands at 40–55% below ebm-papst K3G1000 ex-works pricing. Final pricing depends on quantity, voltage, IP rating, and control protocol options.
What applications is LWBE3G630 typically used for?
LWBE3G630 is widely deployed across Heavy mining ventilation, cement kiln induced-draft, steel sintering exhaust. Particularly suited for heavy mining ventilation and cement kiln induced-draft duty.
