Import 500mm Non Power Turbine Fan Ventilator — Buy in Bulk from Supplier in China

The AP500-I is a 500 mm non-powered turbine ventilator manufactured by Shanghai Aipu Environmental Protection Technology Co., Ltd. in China, designed for roof-mounted natural ventilation without electrical consumption. The unit measures 600 mm in total height with a turbine diameter of 620 mm and a ventilation diameter of 490 mm, matching the base plate diameter of 490 mm. It operates on convection principles, converting parallel airflow into vertical exhaust through wind-driven rotation, with 25 stainless steel blades providing continuous air exchange. The absence of electrical components means zero running costs and minimal maintenance requirements over the product lifespan.

The ventilator body and supporting brackets are constructed from stainless steel, offering corrosion resistance suitable for industrial environments including galvanisation and coating facilities. All units incorporate American UBC bearings that require no lubrication, reducing long-term service needs. The design exploits natural thermal buoyancy, hot air rises and cold air falls, to initiate and sustain rotation, effectively exhausting heat, odour, moisture, and airborne contaminants. Standard industrial applications for this type of non-powered ventilator include warehouses, manufacturing workshops, paper mills, and sports halls where passive air exchange is preferred.

Buyers typically deploy this model in facilities requiring continuous ventilation without energy input, particularly where humidity control and fume extraction are priorities. The 500 mm class suits medium-scale industrial and commercial roofs with adequate structural loading capacity for the 620 mm turbine diameter. When sourcing from Shanghai Aipu, buyers should confirm mounting hardware specifications, local wind load ratings for the installation site, and whether the 490 mm base plate matches existing roof penetrations. Packaging is carton-based, so transit damage prevention during international shipment warrants discussion with the supplier.

Shanghai Aipu Environmental Protection Technology Co., Ltd. is located at C, No.1916, Zhongchun Road, Shanghai 201108, China, placing it within the Yangtze River Delta manufacturing corridor with access to Shanghai Port for export logistics. The company holds a harbor trust tier on the platform, though its response rate is recorded at 0.00 percent with average response hours at zero, indicating minimal or no historical engagement through the platform messaging system. This profile does not disclose factory size, year of establishment, revenue, employee count, or specific export markets served.

The listing presents the AP500-I turbine ventilator as a passive ventilation solution for industrial and commercial buildings, with no mention of ISO certification, patent holdings, or OEM/ODM capabilities in the available data. The supplier's product range, as far as this listing indicates, centres on roof-mounted natural ventilators rather than powered exhaust systems. Buyers should note that the absence of response history means direct communication channels, email or telephone via the provided Shanghai address, may be necessary for technical clarifications, customised mounting solutions, or volume quotations. No client references, case installations, or after-sales service networks are stated.
