Import 20ft Hvls Cooling Ceiling Fans — Buy in wholesale FOB from Supplier in China

The 20ft HVLS (High Volume Low Speed) Cooling Ceiling Fan is an industrial-scale ventilation device designed for large-scale air circulation in commercial and agricultural facilities. With a blade diameter of 20 feet (approximately 6100mm), this fan moves massive volumes of air at low rotational speeds, creating a gentle downward air stream that covers areas up to 20,000 square feet. The fan operates using a direct-drive motor system with typical industrial voltage configurations of 380V three-phase or 220V single-phase, drawing between 1500-2500 watts depending on the motor efficiency rating. The knocked-down packaging format allows for efficient international freight, with the fan shipped in multiple cartons containing the aluminum blades, motor assembly, and galvanized mounting hardware separately crated.

The blade assembly consists of aircraft-grade aluminum alloy blades (typically 6063-T5 or similar structural alloy), which offer an optimal balance of strength to weight ratio for large-diameter applications. The motor housing is constructed from rolled steel with protective powder coating or enamel finish to resist corrosion in industrial environments. Mounting hardware utilizes hot-dipped galvanized steel components rated for outdoor or high-humidity installation, with typical mounting heights ranging from 20 to 45 feet depending on ceiling structure. The fan operates at low rotational speeds (typically 30-70 RPM) which generates minimal mechanical noise, usually below 65 dB at 10 meters, making it suitable for occupied workspaces where lower sound levels are required.

These HVLS fans are primarily purchased by facility managers, warehouse operators, agricultural enterprises (dairy farms, poultry facilities, grain storage), manufacturing plants, and logistics center operators. The primary applications include temperature stratification reduction, humidity control, worker comfort improvement, and air quality maintenance in spaces where traditional HVAC is insufficient or cost-prohibitive. Trade terms commonly offered include FOB (Free on Board) and CIF (Cost, Insurance, and Freight) with flexible MOQ arrangements. Buyers should verify specific certification requirements for their destination country, as industrial equipment may require local electrical safety approvals beyond the listed ISO and CE compliance markers.

Jiangsu Dawang Ventilation Machinery Co., Ltd is a Chinese industrial ventilation equipment manufacturer based in China with postal code 214000. The supplier operates on the harbor trust tier, which indicates basic verification of business registration and contact information. The listing does not disclose company founding year, annual production capacity, employee count, or export destination countries.
