The Swifter Industrial Ceiling Fan is a new and revolutionary large-scale ceiling fan designed specifically for use in commercial applications. These HVLS Ceiling Fans belong to a category of fans referred to as High Volume, Low Speed (HVLS). This means that these large-span ceiling fan can move high volumes of air at low speeds. Swifter HVLS Ceiling Fans are indeed very big fans. They are available in various standard sizes; 10, 12', 14' and 16' diameter. Glocon has a proven history for developing new and innovative industrial fan products. We have positioned the Swifter HVLS fan series as possibly the best industrial ceiling fan on the market: Features of the Swifter Industrial Ceiling FanBenefits of the Swifter Industrial Ceiling FanHybrid Fan SystemDirect Drive Permanent Magnet MotorUniversal Voltage InputHoisting System *Composite Fan BladesPatented High Efficiency AirfoilFolding Hinged Fan BladesAdjustable Fan Pitch AngleHigh Strength Hub AssemblyWash-Down Fan AssemblyAuto-Interference Shut OffInvisible Accident Avoidance Shield *Forward and Reverse OperationVariable Speed OperationLED Mode Indicators *Wall Mounted ControllerWireless Handheld Remote *Safety Shut-Off Switch10-Year Product WarrantyOperates on electric grid power, using as little as 500 watts. Or, with the optional solar package accessory, run the fan on clean solar power.Eliminates the need for a gearbox speed reducer. This results in higher efficiency, simplified design and lower fan weightFan can be configured for voltage inputs of 110-480 VAC, 5060 Hz, Single or three phase andor 48 VDCFan can be easily lowered or raised for simplified installation or maintenance. The result is lower install and operating cost.Fiberglass reinforced plastic (FRP) fan blades are lightweight and corrosion resistantPowerful blade airfoil provides greater airflow at lower power resulting in fewer fan blades and lower solidity ratioRetractable fan blades can be folded up for easier handling and maintenanceAdjust fan blade pitch angle for airflow optimization for differing ceiling heights and facility configurationsFan hub is constructed of carbon steel, stainless steel, extruded aluminum and stock aluminum. This results in a structurally superior hub design.Easy cleaning and maintenance. Fan can be used indoors or outdoors. Water and moisture will not affect fan operation; the motor and electronics are sealed.Fan stops and sounds alarm if an external object interferes and restricts fan rotationInfrared shield stops fan operation and sounds alarm when an object approaches the proximity of the fan from belowRe-circulate air in either direction to achieve summer time evaporative cooling or wintertime warmingControl the amount of air being movedIdentify the mode of operation at a glanceHard-wired control box to turn fan onoff, change fan speed or change forwardreverse direction.Control ceiling fan speed and direction with easeShut down fan immediately with wall switchPeace of mind. Any defective part will be replaced.
