Qingzhou Jienuo temperature control equipment Co., Ltd. Department of domestic business   

        our company produces JFD-HE hammer series fan through the National Engineering Laboratory of Department of agriculture of Shandong Province agricultural machinery testing detection and identification station detection, and access to the EU CE safety certification, the quality of the most stable products for the domestic  
- less investment, low energy consumption. The same cooling rate, one-time investment is about air conditioner 1/6, operation cost is about air conditioning 1/10;  
the obvious cooling effect, the temperature dropped to 28 degrees can accord with human body temperature     if the well water as a better tank source effect,   effect can be compared to the air conditioner;
. Air clean degree can reach 99%
- high quality, moderate price, especially suitable for planting in greenhouse.  
- price moderate, can meet the needs of different consumers.  
B: features:  
- frame: the use of automatic advanced processing technology, a molding, thick galvanized layer (150  g/m2), corrosion resistance is strong, at the bottom of the water outlet.  
- belt pulley; aluminum alloy V type wheel, hot pressure casting molding, material is light, high strength, good toughness, no fracture;  
- Fan: 6 new once punch forming of stainless steel blades, not deformation, not broken, beautiful and durable. The machine through dynamic balance test, the reasonable leaf angle, produces air flow to ensure, have very low noise.  
the shutters;   high strength hot dip galvanized plate, auto open device adopts unique shutter, (weight); ensure the blinds completely open and close, keep any case 90 degrees open, so that the shutter to not choke, windproof, rainproof, dustproof;  
the hammer opening and closing mechanism: the switch mechanism, is the use of two without power 100 turn heavy hammer, configure automatic device to realize, windproof, dustproof, waterproof shutter reach;  
- motor; using V type belt transmission, high efficiency and energy saving motor configuration, GB, through the 3C certification, protection grade: IP54, insulation grade: F;  
- belt: imported B type belt, no deformation, long service life; maintenance free during the whole service period.  
- detection: strict quality testing procedures: Six noise detection, vibration detection, rotary concentric performance detection, speed detection, air flow measurement of wind in the leaves, the whole efficiency detection;  
C:  
- with wet curtain: used as workshop cooling the scorching summer, no matter how hot your workshop, fan system wet curtain - negative pressure can let you workshop temperature reduces about 8-10C, but also a certain degree of humidity.  
- negative pressure fan applicable scope:  
A, applicable to high temperature or smell of the workshop: such as heat treatment plant, casting factory, plastics factory, aluminum profile factory, shoe factory, leather factory, electroplating factory, chemical factory.  
B, suitable for labor-intensive enterprises: such as clothing factory, all kinds of assembly workshop, the Internet bar.  
C, horticultural greenhouse ventilation cooling, animal husbandry field cooling.  
D, especially suitable for the need to cool and need a certain humidity place. Such as cotton mill, woolen mill, textile factory, weaving factory, chemical factory, warp knitting factory, texturing factory, knitting factory, silk mill, socks factory of all kinds of textile factory.  
E, suitable for storage and logistics area  
- as the exhaust fan exhaust fan current use: General (commonly known as winnowing fan) performance is poor, a fan blowing to several people, otherwise, the negative pressure fan, whether on the ground using or hang in the air for. General 1000 square meters workshop in the use of 4 units, that is a whole room is the effect of the wind.
