Guard-equipped EC axial fan design update
On August 5, 2026, LONGWELL opened a project to update model LWAE3G200ST-7PKW-17 to a guard-equipped axial fan configuration. The engineering team processed the design requirements and established model designation LWAE3G200ST-7PEW-17-00. The standard technical specification was completed on August 6, 2026.

Wiring and guard dimensions
The updated layout features an integrated grill guard with outer diameter dimensions of 336 mm and 320 mm mounting diameter. Airflow moves axially across the motor hub. Control and power supply connections are arranged with dedicated functional leads for supply, 0-10V/PWM speed control, 10VDC auxiliary output, and a tachometer FG output producing 4 pulses per revolution.
