Why Engineers Switch from ZAvblue 1000 to LWAE3G900

4–8× Faster Delivery

15–30 days
vs 16–22 weeks ex-works for Ziehl-Abegg 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

Ø900 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 Ø900 mm (LWAE3G900); 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 LWAE3G900 accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as Ziehl-Abegg ZAvblue 1000. LONGWELL supplies its Modbus RTU register map with the fan so the BMS points can be re-mapped; the register addresses are not identical to the Ziehl-Abegg map.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 LWAE3G900 is widely deployed across mega dry cooler, hyperscale cooling tower. Common application categories include:

  • Mega dry cooler
  • Hyperscale cooling tower

Particularly suited for hyperscale cooling tower and mega dry cooler installations.

FAQ

Is LONGWELL LWAE3G900 a true drop-in replacement for Ziehl-Abegg ZAvblue 1000?
Not as a drop-in: LONGWELL does not list a Ø1000 mm model in this family. The nearest listed size is Ø900 mm (LWAE3G900); for equal airflow we propose a FanGrid array of smaller EC units or a custom development. Ask engineering with your duty point.
How does LWAE3G900 compare on efficiency to ZAvblue 1000?
LONGWELL does not publish a single peak-efficiency figure for the LWAE3G900. 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: Ziehl-Abegg ZAvblue 1000 requires 16–22 weeks ex-works due to ongoing allocation. LONGWELL LWAE3G900 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 LWAE3G900 typically lands at 40–55% below Ziehl-Abegg ZAvblue 1000 ex-works pricing. Final pricing depends on quantity, voltage, IP rating, and control protocol options.
What applications is LWAE3G900 typically used for?
LWAE3G900 is widely deployed across mega dry cooler, hyperscale cooling tower. Particularly suited for hyperscale cooling tower and mega dry cooler installations.
