One unit creates a perceptible breeze over a circle up to 44 m across (about 1,450 m2) while staying below 39 dB(A). It is offered in 220 V single-phase and 380 V three-phase versions, each covered by its own factory type-test report. ## Why projects specify this RDF HVLS fan - **Gearless PMSM servo direct drive.** The permanent-magnet synchronous motor is built into the hub - no gearbox, no oil, no seals to service. Independent conformity assessment covers EMC Directive 2014/30/EU and LVD 2014/35/EU for the drive motor. - **Very large air volume, very low input.** Up to 15,197 m3/min from 1.3 kW installed power, with typical consumption below 1 kWh per hour in normal operation. - **Quiet by design.** Six airfoil-section blades turn at 55-90 rpm, keeping sound below 38-39 dB(A) - quieter than typical office background noise. - **Engineered for safety overhead.** One-piece anodised aviation-grade Al-Mg blades with six reinforcement ribs and T6 heat treatment, on a 45# steel petiole with the patented starfish-claw triple-bolt anti-drop hub. - **IP64 sealed motor.** Dust- and splash-protected, brushless and maintenance-free, with a separate protection-grade test report on file. - **Smart vector control.** Infinitely variable speed, soft IPD start, RFI filtering and overload protection; the 7.2 m model has independent type-test reports for both 220 V and 380 V builds. ## Technical specifications | Model | Diameter | Power supply | Current | Power | Max. speed | Max. airflow | Noise | Net weight | Coverage | | ----- | -------- | ------------ | ------- | ----- | ---------- | ------------ | ----- | ---------- | -------- | | RDF-S3600 | 3,600 mm (12 ft) | 220V/50Hz, 1-phase | 3.0 A | 0.66 kW | 90 rpm | 4,522 m3/min | <38 dB | 72 kg | O 20-24 m | | RDF-S4200 | 4,200 mm (14 ft) | 220V/50Hz, 1-phase | 3.0 A | 0.66 kW | 80 rpm | 5,306 m3/min | <38 dB | 75 kg | O 22-26 m | | RDF-S5200 | 5,200 mm (17 ft*) | 220V/50Hz, 1-phase | 3.0 A | 0.66 kW | 70 rpm | 7,065 m3/min | <39 dB | 78 kg | O 25-30 m | | RDF-B6200 | 6,200 mm (20 ft) | 220V/50Hz, 1-phase | 4.4 A | 1.3 kW | 65 rpm | 10,747 m3/min | <39 dB | 100 kg | O 32-37 m | | RDF-B6200 | 6,200 mm (20 ft) | 380V/50Hz, 3-phase | 3.0 A | 1.3 kW | 65 rpm | 10,747 m3/min | <39 dB | 100 kg | O 32-37 m | | RDF-B6700 | 6,700 mm (22 ft) | 220V/50Hz, 1-phase | 4.4 A | 1.3 kW | 60 rpm | 12,560 m3/min | <39 dB | 105 kg | O 35-40 m | | RDF-B6700 | 6,700 mm (22 ft) | 380V/50Hz, 3-phase | 3.0 A | 1.3 kW | 60 rpm | 12,560 m3/min | <39 dB | 105 kg | O 35-40 m | | RDF-H7200 | 7,200 mm (24 ft) | 220V/50Hz, 1-phase | 4.4 A | 1.3 kW | 55 rpm | 15,197 m3/min | <39 dB | 115 kg | O 38-44 m | | RDF-H7200 | 7,200 mm (24 ft) | 380V/50Hz, 3-phase | 3.0 A | 1.3 kW | 55 rpm | 15,197 m3/min | <39 dB | 115 kg | O 38-44 m | Airflow at maximum speed per the manufacturer type test; running speed is infinitely variable. The 5.2 m model's printed "14 ft" in the source brochure is a brochure typo; the manufacturer's Chinese-market spec table lists 5.2 m = 17 ft, the correct conversion. ## Where the 7.2 m fan earns its keep The bigger the swept area, the lower the rpm and the energy needed to move the same air. The H7200 is the choice for high-bay, unobstructed spaces: logistics and e-commerce warehouses over 8 m clear height, large production bays, exhibition halls, 4S dealerships and wholesale markets. On most projects we lay out the fans on a 35-40 m grid at 8-15 m mounting height and run them well below maximum rpm - that is where HVLS fans are most efficient and quiet. Multiple fans overlap at their edges so there are no dead zones between racking aisles or production lines. Need smaller fans for lower ceilings? The same direct-drive platform runs from 3.6 m (12 ft) upward - see the related products below. ## Backed by a specialist air-treatment manufacturer - 20+ years focused on evaporative cooling and large industrial fans; National High-Tech Enterprise and CRAA-listed manufacturer. - Deputy Director Unit of the national evaporative-cooling industry committee, with 40+ patents and self-developed, patented molds. - Product liability underwritten by CPIC (policy ADNGD0207121Q000109N); type-test, protection-grade and CE motor-conformity documentation supplied with export orders. - RDF equipment is published in service with automotive, food and electronics manufacturers including SAIC-GM-Wuling, FAW-Volkswagen, GAC Toyota/Honda, PepsiCo, Foxconn, Panasonic, Gree, Midea and Haier. ## Ordering the RDF-H7200 7.2 m HVLS fan - **MOQ:** 10 units - **Lead time:** 10 units in about 5 days; 100 units in about 20 days; 500 units in about 60 days - schedule varies by model and production plan, confirmed per order - **Trade terms:** FOB Shenzhen - **Payment:** T/T - 35% deposit, 65% balance paid before shipment - **Warranty:** 2-year warranty on the complete unit per the factory's warranty policy: motor 2 years, controller 2 years.

Nameplate power is 1.3 kW; in normal comfort operation the fan usually runs below maximum speed, so measured consumption is typically under 1 kWh per hour - a fraction of moving the same air with high-speed pedestal or wall fans. ### What is the difference between the 220 V and 380 V versions? Both deliver 15,197 m3/min. The 220 V single-phase unit draws 4.4 A and suits buildings without three-phase supply; the 380 V three-phase unit draws 3.0 A and is standard for industrial premises. Each has its own type-test report. ### Can it be installed over racking or production lines? Yes. The patented starfish-claw hub uses a triple-bolt anti-drop fixing on a 45# steel petiole, the motor is IP64, and the drive train is gearless - no oil or wearing gearbox above people or stock. A safety cable and certified bracket are part of the installation kit. ### How many fans does my warehouse need? As a rule of thumb one H7200 covers an effective O 38-44 m circle at 8-15 m height. Send dimensions and column layout and we return a marked-up fan layout free of charge. ### How loud is it at working height? Below 39 dB(A) at rated speed - close to a quiet library. Variable speed allows lower settings in occupied comfort zones. ## Related products - [Large-Diameter HVLS Ceiling Fan - full 3.6-7.2 m range](/product/large-diameter-hvls-ceiling-fan/) - [PMSM Servo HVLS Ceiling Fan - drive technology](/product/pmsm-servo-hvls-ceiling-fan/) - [HVLS Fans for Warehouses](/product/hvls-fans-for-warehouses/) - [Energy-Saving Industrial Ceiling Fan](/product/energy-saving-industrial-ceiling-fan/) ## More from TierCooling - [View installed project references](/projects/) - [About the manufacturer](/about/) - [All products in this category](/product-category/hvls-ceiling-fans/) ## FAQ ### What does HVLS mean? High Volume, Low Speed: large-diameter ceiling fans that move a very large air volume at low rotational speed, covering big floor areas with gentle, even airflow instead of concentrated high-speed blasts. ### Why choose a PMSM direct-drive HVLS fan? Permanent-magnet synchronous motors with direct drive run at high efficiency with fewer wearing parts than geared designs - meaning lower energy use, quieter operation and less maintenance over the fan's life. ### Which sites use HVLS ceiling fans? Typical applications include factories, warehouses, gyms and sports halls, markets and malls, playgrounds and sports fields, and livestock farms - any large space where uniform airflow and lower energy cost matter. ### How is fan size and unit count decided? Selection comes from floor area, mounting height and the obstruction layout of the site; suppliers model diameter and placement from drawings so airflow reaches working zones evenly.
