the big HVLS fan(RTF-CF-7E)

RTFANS industrial fan system used for factory HVLS(high Volume, Low Speed) fan, it is a super large energy-saving industrial ceiling fan with diameter up to 7.3 meters (24ft). Product details Product Name: Industrial Fan Brand Name: RTFANS Size: 12ft 16ft 18ft 20ft 24ft / 3.7m 4.9m 5.5m 6.1m 7.3m Mounting: Ceiling Fan Power: 1500W Voltage: 220V/380V Warranty: 3 years Number of blades: 6 Certification: ISO9001:2015; IOS14001:2015; CE;RoHS Product Keywords industrial fan system The airfoil blade is streamlined, which are developed with the advanced technologies and the principle of aerodynamic. Unlike a small, high-velocity fan that creates small, turbulent air streams that quickly disperse. Ifan relies on size, not speed, to move a significant amount of air, it result is a silent, non-disruptive and even distribution of 1~3m/s breezes over large spaces. Just with a power of 1.5kw or less, the HVLS fan are able to move a mass of air and then produce a large scale of natural wind, which leads to the double functions of ventilation and cooling.
