Clearflow CF500 Roof Fan Three Phase AC 500mm

The Elta Clearflow CF500/4-3AC is a 500mm vertical discharge centrifugal roof fan moving up to 9576 m³/h in free air, rated in the Elta datasheet to 500 Pa. It can be mounted at angles up to 30°, so it fits straight onto pitched roofs as well as flat roof upstands.A three phase AC external rotor motor with sealed for life bearings drives a backward curved impeller with 7 fluted composite blades, inside an all metal pre-galvanised steel casing. A bird guard and removable wind guard are fitted as standard, the motor is rated for air up to +60°C and Elta give a 12 month warranty. 3 Phase AC Motor Up to 9576 m³/h Speed Controllable What it is best used forThe largest Clearflow, for factory and warehouse roof extract, foundries and large kitchens with long duct runs, moving about 8982 m³/h at 100 Pa and still 3168 m³/h at 500 Pa.The standard Clearflow is rated for air up to +60°C with the motor in the airstream. For hot or grease laden extract straight off a cooking canopy, use the Elta Clearflow CFHT500 instead, which keeps the motor out of the airstream and handles up to +120°C.Why choose this over alternativesVertical discharge throws odours and contaminated air up and away from occupied areas and roof walkways, and because the fan sits on the roof it saves plant space inside. The backward curved impeller with 7 fluted composite blades is designed for high efficiency at the operating point with low noise, and the bird guard and wind guard come fitted as standard.If a smaller unit will do, the Elta CF450/4-3AC moves up to 7844 m³/h and is rated to 500 Pa.For grease laden or high temperature extract, the Elta Clearflow CFHT500 is the matching high temperature roof fan, with its motor out of the airstream.Installation notes The unit can be mounted at angles of up to 30°, so it can sit directly on a pitched roof without a levelling kerb. The spigot is on the underside of the fan and fits directly to the main duct. For speed control wire through the Elta 149-TC310 5 step transformer controller to Elta wiring diagram 152-106A, with a means of electrical isolation at the fan. The wind guard is easily removed for cleaning and maintenance, so leave safe roof access to the fan.
