Description
1.Broad Dimensional Range.Cross-flow diameters 50-180mm, length up to 1000mm+. Axial impellers from LW151 to LW556. Centrifugal types include forward single/dual-inlet and backward curved. In-house tooling enables rapid OEM size and geometry modifications.
2. Engineered Materials. ABS+GF for standard HVAC duty. Reinforced AS for higher heat tolerance. PP for wet or chemical exposure. Material certification and UV stabilization available. We recommend optimal resin based on operating temperature to ensure service life.
3. Dynamic Balance & QC. CNC in-line balancing to G 6.3 standard minimizes vibration and noise. AQL sampling verifies bore tolerance and concentricity across batches. First-article reports available before volume production.
4. Full OEM Service. Custom RAL/Pantone colors, logo embossing, and white-label packaging supported. Shaft holes 4-12mm, sleeve depth up to 50mm, setscrew flats configurable. Rotation direction (CW/CCW) clearly specified per SKU. NDA protection provided.
5. Export Packaging & Capacity. Polybags, EPE dividers, 5-ply export cartons. ISPM 15 pallets. Scalable production supports both mid-volume wholesale and high-volume OEM. Lead time 15-25 days standard, 25-35 days custom.
6. CAD Design Support. 2D PDF/DWG and 3D STEP files available for standard impellers. Custom models generated for approval before tooling. Ensures accurate hub fit and blade clearance within your assembly.
7. Application Versatility.Impellers suit AC condensing units, air curtains, ventilation fans, heaters, and purifiers. Backward curved options support higher static pressure. Forward curved suits compact high-flow designs. We guide selection based on your system curve requirements.
8. Reliable Supply Chain.Manufacturing based in Yuyao, Ningbo-China’s HVAC component hub. Consistent resin sourcing and in-house molding capacity ensure stable delivery for long-term OEM programs. Sample orders available for performance validation.
