Product Name: Greenhouse /Industrial/Chicken House /Negative-Pressuer Exhaust Fan Model NO.: JFD-1250HE Certification: UR, ISO, CE, CCC Mounting: Wall Fan Electric Current Type: AC Type: Exhaust Fan Blade Material: Stainless Steel Material: Galvanized Sheet Power: 1.1kw Trademark: JIENUO Transport Package: Paper Carton Specification: CE, SGS Origin: Shandong, China HS Code: 84148090 Product Description Jienuo JFD-HE exhaust fan is quality built, CE compliant, and meets applicable national and industrial standards, thus, customers can fell secure using it.AdvantagesCompared with air conditioning that produces the same cooling effect, Aonuodi standard exhaust fan requires reduced cost of ownership and operating coat, which are respectively 80% and 90% lower that that if conditioning.The exhaust fan can reduce the temperature to 28 degree, it can achieve even better effect if using well water as the source of the water tank.Fresh, moist air: The cleanliness of air can be up to 99%.Reliable quality and economical price make our standard exhaust fan the ideal product for greenhouse.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 galvanized plate, the hammer device makes it possible to open and close louvers completely, maintain a 90-degree opening angle to ensure louvers are windproof, rainproof and dustproof.Motor: V type belt is durable, high energy efficient, 3C approved, IP54, class F insulation.Belt: imported B type belt is long lasting, deformation resistant, and requires no maintenance.Tests: Aonuodi standard exhaust fan is subjected to noise test, vibration test, concentric performance test, fan blade speed test. Air flow test and efficiency test, so as to ensure its quality.Applications1. Jienuo standard 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.2. The exhaust fan can be used 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.3. It can be used for cooling greenhouse, stock farm.4. The standard exhaust fan also used in the storage, logistics, and other fields.ModelBladeDiametermmFanspeedr/mInputpowerKWCurrentAAirVolumem3/hDimensionsmmWeightkgJFD-900HE9005600.551.5320001000*1000*40045JFD-1000HE10005600.752350001100*1100*40050JFD-1100HE11005050.752400001220*1220*40061JFD-1250HE12504201.12.8460001380*1380*40071JFD-1400HE14004201.53.8550001530*1530*40080
