Project scope and engineering request
The requirement was for a 24V DC speed-controlled axial fan with a 300 mm diameter and a protective guard grill, based on a standard product configuration. On April 11, 2026, LONGWELL opened a project to evaluate the requirements. LONGWELL engineering completed the preliminary evaluation and model designation, assigning part number LWAD3G300MS-5PEW-07-00, and output the standard technical specification on April 14, 2026.
Technical parameters and features
The standard specification defines an axial fan operating on 24 VDC nominal voltage, fitted with speed control functionality accepting 0–10 VDC or PWM control signals. The physical assembly includes a protective guard grill and an impeller manufactured from glass-fiber reinforced polyamide (PA6+GF).
