China Factory Specialized Exhaust Fan Greenhouse Fan

Factory specialized exhaust fan Greenhouse fan

* the unique push louver mechanism can automatically open and close the louver blades

* stainless steel fan blade a stamping process, no deformation, no fracture, beautiful and durable

* high precision dynamic balance detection and correction, ensure the fan running smoothly without vibration, reduce noise, effectively improve service life

* the use of concave fan handling handle design, not only effectively avoid the handling process of inconvenience, but also will not affect the fan installation and aesthetic effect

*V belt pulley is formed by hot die-casting of high-strength aluminum-magnesium alloy material, with light material and high strength

* equipped with efficient energy-saving motor, it has passed 3C certification, with protection grade: IP55 and insulation grade: F

* mechanical centrifugal opening mechanism adopts 100% reinforced nylon raw material injection molding with high toughness, high strength and long life

* the steel parts embedded in the guide bar are installed on the flange sheet, which enhances the reliability of the mechanism and effectively avoids the expansion and expansion in the nylon production process

* the fan blade is made of krupp stainless steel, dust-free, beautiful and durable.Special blade shape design ensures large air volume, no deformation, no fracture, make air volume the same all the way, the blade rivet by ring groove, never loose

* the push and pull mechanism can fully open the shutter, ensuring less air resistance and larger air volume.When closed, it can effectively prevent wind, rain and dust.Use high quality nylon 100% raw material injection processing.The push and pull mechanism of fastener is copper rivet, wear-resisting, rustless and flexible.The guide rod is made of 304 stainless steel, which ensures high strength, no rust and less friction.
