Import Air Diffuser — Buy in Bulk from Supplier in China

This aluminum alloy air diffuser is built for ceiling-mounted HVAC distribution in commercial and residential buildings, featuring a fixed 30-degree vane angle for directional throw control. The register face allows one-way, two-way, three-way, or four-way airflow configurations, selected at installation to match room geometry and load requirements. The body is extruded aluminum with a natural or powder-coated finish, sized to standard Chinese modular ceiling grids of 600 mm x 600 mm. No performance airflow rates, neck sizes, or pressure-drop data are stated in the listing, so buyers should request a fan-powered or duct-connected performance table before specifying.

The 30-degree vane angle is a common industry setting for moderate-throw supply air, balancing horizontal projection with rapid mixing in the occupied zone. Aluminum construction resists corrosion in normal indoor environments and keeps weight low for suspended ceiling applications. Multi-directional cores are typically field-rotated or factory-set; confirm with the supplier whether the damper or core is removable for cleaning and whether opposed-blade or parallel-blade control is offered. Standard industry practice uses EPDM or felt gaskets on the flange to prevent ceiling staining from leakage; buyers should verify gasket material and flange depth against their suspension system.

Target buyers include mechanical contractors, HVAC wholesalers, and facilities managers fitting office complexes, schools, and healthcare buildings in warm-climate regions where cooling-dominant diffusion is needed. The product suits new construction and retrofit ceiling replacement. Trade terms and MOQ are not disclosed in the source data; confirm FOB Shunde or Shenzhen port options, typical carton quantities per pallet, and whether sample units are available for airflow testing before bulk commitment.

Foshan Chancheng Hualianda Air Conditioner Purification Equipment Manufactory is located at the South Side of Poyang New Industrial Zone, Guilan Road, Lanshi Town, Foshan 528200, Guangdong Province, China. The supplier tier is marked as imported with a harbor trust tier, indicating a baseline listing without additional verification badges. The response rate is shown as 0.00 percent with zero average response hours, which suggests the profile may be inactive or that response metrics have not been recorded.

The company name indicates specialization in air conditioner and purification equipment manufacturing, though the listing provides no factory size, year of establishment, revenue, or client references. Buyers should treat the profile as an unverified manufacturing source and conduct direct due diligence: request factory audit reports, ISO 9001 or ISO 14001 certificate copies with registration numbers, and at least two reference projects with contactable mechanical contractors. The address places the facility within Foshan's industrial belt, a region with dense HVAC component manufacturing, but proximity to other suppliers does not confirm this factory's current production capacity or quality system.
