EC axial fan specification request
On July 30, 2026, LONGWELL opened a project to prepare a technical specification for the EC axial fan model LWAE3G350S5-5PEW-09. On August 1, 2026, LONGWELL engineering output the standard technical specification document for model LWAE3G350SS-5PEW-09-00.
Electrical and mechanical specifications
The compiled technical specification details the specified ratings and mechanical construction for the 350 mm EC axial fan assembly.
| Parameter | Value / Specification |
|---|---|
| Nominal Voltage | 230 VAC (198~277 VAC range, 50/60 Hz) |
| Input Power / Current | 188 W / 1.4 A |
| Speed / Maximum Airflow | 1700 rpm / 3432 m³/h (2019 CFM) |
| Impeller Material | PA6 + 30% GF |
| Protection & Insulation | IP54, Class F, S1 continuous work system |
| Operating Temperature | -25°C to +60°C |
Control interface and lead configuration
The fan design incorporates multi-input control capabilities and signal feedback. Wiring is allocated into power and control lead groups:
- Power Lines (L1): Brown (Live), Blue (Neutral), Yellow/Green (Ground PE).
- Control & Signals (L2): Red (+10VDC auxiliary output, max 10 mA), Blue (GND signal ground), Yellow (0–10 VDC / PWM speed control input), Green (FG tachometer output, 1 pulse/rev), and Brown (4.5–20 mA current loop control input).
Technical deliverable
The revised specification document serves as the deliverable for fit evaluation:
