Plastic cross flow impeller technical specification
On June 24, 2026, LONGWELL opened a project to prepare a standard technical specification drawing for a plastic cross flow fan impeller under model number LWPI-Φ107X762-01. The specification defines a 107 mm outer diameter cross flow impeller with a body length of 762 mm (±2 mm tolerance) constructed from AS+GF30% material in blue color.
The drawing outlines mechanical interfaces, dimensional tolerances, and quality criteria. The shaft end feature includes an M4X6.5 set screw on an 8 mm shaft interface (+0.022 / 0 mm tolerance), with counterclockwise (CCW) rotation viewed from the A-A steel shaft end.

Documented engineering requirements
The detailed technical notes defined on drawing LWPI-Φ107X762-01 establish specific manufacturing and mechanical criteria:
| Parameter / Requirement | Specification Value |
|---|---|
| Model Number | LWPI-Φ107X762-01 |
| Impeller Outer Diameter | Φ107 mm |
| Impeller Length | 762 ±2 mm |
| Shaft Extension Diameter (Drive End) | Φ8 (+0.022 / 0) mm |
| Shaft Extension Diameter (Opposite End) | Φ6 (0 / -0.01) mm |
| Material | AS + GF30% |
| Color | Blue |
| Dynamic Unbalance Limit | ≤ 0.3g under 1200 rpm condition |
| Radial / Axial Runout Limit | Blade radial < 0.7mm, axial < 0.6mm, shaft runout < 0.2mm |
Additional parameters specify that blade connections are ultrasonic noise-wave welded without false or leakage defects. The wheel structure allows a maximum of 3 balancing clips, with no abnormal sound permitted when tested up to 1600 rpm. Technical review was completed on June 25, 2026, delivering the finalized drawing LWPI-Φ107X762-01 for structural and fit evaluation.
