Product Name: Centrifugal Exhaust Fan /Ventilation Fan for Poultry Farm and Greenhouse Model NO.: yuge Certification: CSA, RoHS, UR, ISO, UL, CE, CCC Mounting: Free Standing Electric Current Type: DC Type: Exhaust Fan Blade Material: Stainless Steel Material: Aluminum Fan Trademark: yuge Transport Package: in Cartons Specification: 11Specifications Origin: Shandong, China HS Code: 8548900001 Product Description Product Description Advanced exhaust fanYuge exhaust fan is quality built, CE compliant, and meets applicable national and industrial standards, thus, customers can fell secure using it.AdvantagesLow cost, low energy consumption: advanced exhaust fan costs on sixth of the air conditioning and using nearly 90% less energy than it, while producing the same cooling effect.Significant cooling effect. The exhaust fan can reduce the temperature to 28 degree, it can achieve even better effect if using water as the source of the water tank.Fresh, moist air: The cleanliness of air can be up to 99%.FeaturesFan frame: It is formed in one step due to the use of advanced automatic processing technique, the thick zinc coating (150g/m2) ensures great corrosion resistance, the bottom outlet design makes fan structure more reasonable.Belt pulley: The V-shaped hub made of aviation aluminum alloy is light, tensile, high-strength, and unlikely to break.Fan blade: Six stainless steel blades which are formed in one step are aesthetic, durable and resistant to deformation, the blade passed the dynamic balance test and its reasonable angle ensures maximum air flow and minimum noise.Shutter: High strength hot galvanised plate, the automatic opening-closing device makes it possible to open and close louvers completely, maintain a 90-degree opening angle to ensure louvers are windproof, rainproof and dustproof.Shutter opening-closing device: Made using tensile industrial nylon and injection molding technique, the device features high strength and long life. As the guide bar is inlaid with metal sheet, its strength is greatly increased, contributing to the reliability of the opening-closing device.Motor: Energy efficient, 3C approved, IP54, class F insulation.Belt: imported B type belt is long lasting, deformation free, and requires no maintenance.Belt tensioner: It is created with aluminum-magnesium alloy so that it has the advanced of long service life and no deformation, the adoption of the inner tensioning can effectively prevent reverse distortion of the belt and thereby extend its lifetime.Quality tests: Aonuodi advanced exhaust fan is subjected to a series of tests, including noise test, vibration test, concentric performance test, fan blade speed test. Air flow test and efficiency test, to ensure customers receive superior quality exhaust fan.Our advanced exhaust fan has founded a wide variety of applications in many fields.VentilationThe exhaust fan is installed outside the workshop window to remove smelly gases, it is usually used in heat treatment plant, casting plant, plastics plant, garment factory, chemical plant, ect.Used in combination with evaporative cooling pad to lower the temperature of workshop.The advanced exhaust fan together with evaporative cooling pad can reduce the temperature by 8-10 degree while not compromising on the humidity, it is suitable for use in all kinds of textile mills, such as cotton mill, weaving factory, chemical fiber plant, warp knitting plant, ect.Used for cooling greenhouse, stock farm.Used in the storage, logistics, and other fields. Features:1. Centurifugal system: Made of high quality nylon, high intensity, long service life.2. Adopt one -off molded stainless steel blades, no distortion, no broken, attractive durable. Pass the homeostasis test to ensure smooth operation, low noise, long service life.3. Handles: Designed as recessed type, easy for carry, transport and have no effect on installation and outlook.4. High efficient and energy -saving motor with CCC certifiate.
