LWAD3G300 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

LWAD3G300
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 LWAD3G300 are given on its dimensioned drawing. Compare them with the installed fan before ordering.

Electrical & control

The LONGWELL LWAD3G300 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 Sanyo Denki 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 LWAD3G300 is typically specified for Japan convenience store cold storage, display case retrofit. Common application categories include:

  • Japan convenience store
  • Cold display
  • Reach-in cooler

Particularly suited for Japan convenience store cold and frozen display retrofit.

FAQ

What should I check before using LONGWELL LWAD3G300 in place of Sanyo Denki San Ace Cold Storage?
The impeller diameter is the same. Confirm the mounting hole pattern, inlet ring diameter and shaft height against the dimensioned drawing on the LONGWELL LWAD3G300 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 LWAD3G300?
LONGWELL does not publish a single peak-efficiency figure for the LWAD3G300. 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 LWAD3G300 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 Ø300 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 LWAD3G300 typically used for?
LWAD3G300 is typically specified for Japan convenience store cold storage, display case retrofit. Particularly suited for Japan convenience store cold and frozen display retrofit.
