LWBE3G500 at a glance
Production Lead Time
15–30 days
Ex works for production batches. Stock standard models ship as samples in 1–3 days.
Pricing
Quoted per project
Price depends on model, voltage, control option and quantity. Sample fees are credited in full against the first production order.
Same Impeller Diameter
Ø500 mm
Same impeller diameter; confirm the mounting hole pattern and inlet ring against the LONGWELL drawing before ordering.
Installation and control: what to check
Mechanical
Mounting dimensions, inlet ring diameter, motor shaft height and terminal-box position of the LONGWELL LWBE3G500 are given on its dimensioned drawing. Compare them with the installed fan before ordering.
Electrical & control
The LONGWELL LWBE3G500 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 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 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 LWBE3G500 is typically specified for premium hyperscale CRAH, quiet BESS for residential boundary, urban DCFC. Common application categories include:
- Premium hyperscale CRAH
- Quiet BESS
- Urban DCFC
Particularly suited for hyperscale CRAH with strict acoustic and urban BESS deployments.
FAQ
What should I check before using LONGWELL LWBE3G500 in place of Ziehl-Abegg ZAbluefin 500?
The impeller diameter is the same. Confirm the mounting hole pattern, inlet ring diameter and shaft height against the dimensioned drawing on the LONGWELL LWBE3G500 model page before ordering; the available control inputs (0–10 V / PWM / Modbus RTU) and voltages are listed in the table above.
Where can I find efficiency data for LWBE3G500?
LONGWELL does not publish a single peak-efficiency figure for the LWBE3G500. 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 LWBE3G500 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 Ø500 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 LWBE3G500 typically used for?
LWBE3G500 is typically specified for premium hyperscale CRAH, quiet BESS for residential boundary, urban DCFC. Particularly suited for hyperscale CRAH with strict acoustic and urban BESS deployments.
