ZR series push-pull centrifugal fan.

Frame, frames are made of galvanized board, thickness 1.0mm,galvanizing layer 160g/square meters.Blade, 6 pieces of blades and all the blades are made by 430/201/304 stainless steel, mirror face.Impeller, casting aluminum alloy impeller.Bearing of impeller, permanently sealed bearing, size 633313.Venture, galvanized board, thickness 1.0mm.Blade tip clearance, 25mm.Inlet wind protecting net, spraying paint steel wire, thickness 2.8mm.Electrical motor, national-grade aluminum alloy frame motor, 380V, 1.1KW, 50Hz, 3-phase, 4-pole speed, 1410r/m, IP55, class F, efficiency 90%, top/foot mounted, certification, CCC.(motor can be supplied as demand)Motor bearing, national grade. V-belt, A -type belt, imported from Korea. Shutters, galvanized board, 0.8 mm thickness while the middle piece thickness 1.0mm. Galvanizing layer ,160kg/square meters.Opening system, push-pull centrifugal opening system.Rivets, aluminum alloy and stainless steel rivets.Cable, 1 meter long, strong robber wire.Warranty offer, 1 year for the whole machine.High precision system is assistant by computers, which maximizes the effectiveness of the fan. Ten strict procedures that consist of airflow test, noise test, libration test, drive concentric test, blade RPM test, electric current test and whole machine efficiency test, dynamic balance test, the thickness of the galvanized sheet test, the size of the spare parts test, They assure the quality of the fan.

 Big belt pulley (push-pull centrifugal fan): it used by aluminum magnesium alloy, which is new aerial material, light and high-strength with beautiful shape.

        Motor be specially used for high-performance fan, with updated design for automatic regulating device, the belt doesn’t need manual adjustment. Chinese motor ,Siemens. We can support motor according to customer’s choice and using for local voltage and frequency.

 Opening system : The special and advanced centrifugal system assures the opening angle of the shutter so that air flow can be kept on the smooth high level. It is made of superior quality nylon and a little fiberglass, also it is used rivet, which is made of cuprum so that they will not be antirust. It can ensure the shutter opens with the angle of 90 degree when the whole machine runs the rails.

V-belt, A -type belt, imported from Korea.

 Blades : The mirror face stainless steel blades, the whole machine goes through balance test. Blades are formed by stamping while the angle is suitable, which can make the biggest airflow as well as the smallest noise and not out of shape nor rupture during long using term. Additionally, each set of blades must be tested by balance system before sold, which will make sure the stable and smooth work for the fan.
