RDF **HVLS fans for markets and malls** cover circles of O 20-44 m from a single 0.66-1.3 kW gearless motor at **under 39 dB(A)**, mixing conditioned or ventilated air evenly over shoppers and stalls. ## Why projects specify this RDF HVLS fan - **Quiet enough for retail.** Below 38-39 dB(A) - customers hear the ambience, not the fan. - **Public-space safety package.** Six T6-tempered anodised Al-Mg blades on a 45# steel petiole, the patented triple-bolt starfish-claw anti-drop hub and a secondary safety cable. - **Lower air-conditioning cost in atria.** Mixing stratified air in tall voids means cooled air reaches the trading floor instead of pooling at the roof. - **Humidity and condensation control** in fresh-food and wet-market zones where roofs and cold-rack fronts otherwise sweat in humid months. - **Clean, oil-free appearance.** The gearless direct drive has no oil seal to leak above merchandise or food displays. ## 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. ## Retail and public-space installation Mall atria and hypermarkets over 8 m are typical 6.2-7.2 m installations, often run on BMS schedules tied to opening hours. Standard supermarkets and markets at 4.5-6 m use the 3.6-5.2 m models; the finished fan ships with decorative hub covers so it reads as an architectural fixture rather than industrial equipment. Wholesale and wet markets gain a practical benefit: the continuous gentle airflow keeps stall areas fresher and reduces stagnant, odorous pockets in crowded aisles without disturbing lightweight goods or signage. ## 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 HVLS fan for shopping malls, markets and exhibition halls - **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.

They feel comfortable movement rather than a draught - the defining HVLS effect. Speed presets let management set trading-hours levels versus cleaning/night destratification. ### What safety certification exists above the public? The fan uses the triple-bolt anti-drop hub, steel petiole and independent safety cable; the 7.2 m model has factory type-test reports at 220 V and 380 V and the motor has CE EMC/LVD conformity documentation. Local structural sign-off follows the site survey. ### Can it run from the building management system? The standard vector controller accepts speed commands; the IoT option supports group and scheduled control; the manufacturer's control platform uses standard RS485 communication (one master station manages up to 32 units with external temperature/humidity sensors, as deployed on the evaporative-cooler product line) formal protocol mapping and BMS gateway options for export projects are confirmed at quotation stage. ### Does it help the AC actually work in a tall atrium? That is one of its clearest retail uses: without mixing, cold air drops and hot air stratifies, so upper-floor and ground comfort diverge. The fan equalises the void at a fraction of the cooling kW. ## Related products - [Large-Diameter HVLS Ceiling Fan](/product/large-diameter-hvls-ceiling-fan/) - [HVLS Fans for Gyms & Sports Halls](/product/hvls-fans-for-gyms-sports-halls/) - [7.2 m HVLS Fan (PMSM Direct-Drive)](/product/7-2m-hvls-ceiling-fan-pmsm-direct-drive/) ## 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.
