Newly Louvered High-temperature Controlled Industrial Exhaust Fan

^_^Why you choose our exhaust fan

  A). Fans parts are manufactured by digital machines and precision system is assisted by computers, which maximizes the effectiveness of the fan.

   B), Ten strict testing procedures to keep good quality of the fan: 1), airflow test; 2), noise test; 3), libration test; 4), drive concentric test; 5),  blade RPM test; 6), electric current test; 7), whole machine efficiency test; 8), dynamic balance test; 9),  the thickness of the galvanized sheet test; 10), the size of the spare parts test.

^_^Specification

^_^Details

1. HDH fan blade is special designed for top grade efficiency which made of Krupp stainless steel by puch forming. Large air volume, no deformation, no broken, no dust, attractive and durable. Thickness 1.2mm, surface finish BA grade.

2. Centrifugal system open the shutters at complete 90 degree to ensure the lowest air resistance and biggest air volume. When close, the sealing can efficently block light and wind into the poultry farm house, As the first one adopt high quality nylon PA66 to ensure the long service life. The fasteners of centrifugal system all are copper rivets, wear-resisting and no rust, flexible. Guid rod is made of 304 stainless steel, ensure the high strength, no rust, reduction friction.

3. Shutter fixed parts are made of high quality nylon which ensur elong service life, open flexibly. Shutters are made of galvanized sheet with thickness of 0.8mm and 1.5mm, ensure shutters no deformation, running stable.

4. Belts are Japanese Mitsuboshi brand, ensure the long service life, maintanance lfree.From 2010 the first adopt Type B Belt which 3 times longer service life instead of belt A.

5. Both china famouse motor and Siemens motor are available. Motor voltage and frequency can be customized. Chinese famouse motor OEM by special design for fan, the first put in the phase lack protection device which would powe off when shortage of electricity. Motor protection grade IP55 , insulation class F grade.

6. Fan belt pulley and flange are made of high strength aluminum-magnesium alloy by die-casting. Light weight, lower vinration. 7.Blast-sanding treatment or attractive appearance, eliminate internal stress to improve its own rigidity and stability.

7. Fan side frame with plastic handle easy to carry, convineient to load, reasonable design without injuring hands, beautiful appearance.

8. Motor blade fixed nuts, first change round type,to hexagon type. And with stainless steel washer, more firmly, never loosen.
