On September 7, 2026, LONGWELL’s sales team recorded a customer request to integrate a cross flow fan into a sun umbrella frame. Following a video discussion, the customer asked for samples based on a second mechanical layout.

What the revised layout required
The request removed the guard and L-shaped plate from the proposed assembly and called for wider side plates. The fan, motor and fixing arrangement had to be considered within the umbrella’s frame rather than selected as a separate ventilation unit.
Technical review of LONGWELL’s LWCD-50360MN-01-00 drawing package was completed on September 8. The project also included a manufacturing drawing for the mounting work.
Documented fan configuration
| Parameter | Drawing specification |
|---|---|
| Motor supply | 24 VDC |
| Speed | 2000 ± 10% r/min |
| Speed command and feedback | 0–10 V, FG output |
| Impeller diameter | 50 mm |
| Overall length | 421 ± 2 mm |
The output drawing defines the fan’s mechanical and control interfaces. Its air-volume field is unfilled, so the required airflow through the umbrella assembly needs separate confirmation. The documented result is the drawing package for the proposed configuration and sample preparation.
