hard hat cooling fan

Advantages
Low cost, low energy consumption: Aonuodi 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 28degree,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%.
 
Features
Fan 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.
Ventilation 
  The 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.
