The JFD-E fan produced by our company has passed the testing by the National Agricultural Engineering Laboratory of the Ministry of Agriculture and the Shandong Agricultural Machinery Test and Appraisal Station. It is a stable product in China. ◆ Low investment and low energy consumption. The same cooling rate, the one-time investment is about one-sixth of the air conditioner, and the operating cost is about one-tenth of the air conditioner;
◆ The cooling effect is remarkable, and the temperature can be reduced to about 28 degrees in accordance with the temperature of the human body. If the water from the well is used as the water source of the water tank, the effect is better, comparable to the effect of air conditioning;
◆ The air is fresh and moist. Air cleanliness can reach 99%;
◆ Frame: adopts automatic processing technology, one-time molding, extra-thick galvanized layer (150 g / m2), extremely strong corrosion resistance, and a drain hole at the bottom
Pulleys; aluminum alloy V-shaped wheels, hot-pressed and cast, light material, high strength, good toughness, no break;
◆ Fan blade: 6 new-type one-time stamping stainless steel fan blades, which are not deformed, broken, beautiful and durable. The machine has undergone a dynamic balance test, and its reasonable airfoil angle produces very low noise while ensuring the generation of atmospheric flow.
◆ Blinds; high-strength hot-dip galvanized sheet, using a unique automatic opening device for louvers (push-pull opening and closing mechanism); to ensure that the louvers are fully opened and closed, and kept at 90 ° open under any circumstances, so that the louvers can reach unobstructed, windproof, Protection against rain and dust;
◆ Blade push-pull opening and closing mechanism: It is made of industrial nylon with good toughness and injection molding. It has high strength and long service life. The inlaid metal piece in the guide rod increases the strength of the guide rod and enhances the reliability and service life of the opening and closing mechanism. .
◆ Motor ; energy-saving motor equipped with double-support (E-type) belt drive, national standard, passed 3C certification, protection level: IP54, insulation level: F level;
◆ Belt: B-type belt, non-deformation and long life; free from maintenance during the whole use cycle .
◆ Belt tensioner: aluminum-magnesium alloy material, mold forming bracket, non-deformation and strong service life. The inner side of the belt is tightened to effectively avoid reverse belt distortion and ensure the normal service life of the V-belt.
◆ Detection: Six strict quality inspection procedures: noise detection, vibration detection, rotation concentric performance detection, wind blade speed detection, air volume detection, and overall machine efficiency detection;
Product Application ◆ For exhaust ventilation : It is installed outside the workshop window. Generally, the down-air outlet and exhaust air are selected to extract odor gas. There are many applications in general chemical plants.
◆ Use with wet curtain: It is used to cool the workshop in the hot summer. No matter how hot your workshop is, the wet curtain-negative pressure fan system can reduce the temperature of your workshop by about 8-10C and have a certain humidity.
◆ Application range of negative pressure fan:
A. It is suitable for workshops with high temperature or odor: such as heat treatment plant, casting plant, plastic plant, aluminum plant, shoe factory, leather factory, electroplating factory, and various chemical factories.
B. Applicable to labor-intensive enterprises: such as clothing factories, various assembly workshops, and Internet cafes.
C. Ventilation and cooling in greenhouses and horticultural greenhouses.
D. It is especially suitable for places that need to cool down and need certain humidity. Such as cotton spinning factories, wool spinning factories, hemp spinning factories, weaving factories, chemical fiber factories, warp knitting factories, texturing factories, knitting factories, silk factories, socks factories and other textile factories.
E. Suitable for the field of warehousing and logistics. ◆ Exhaust fan: At present, the general exhaust fan (commonly known as Yanggu fan) has relatively poor performance. One exhaust fan can blow less than a few people, but negative pressure fans are not. Used in the air. Generally, 4 units are used in a 1000 square meter workshop, which means that the full house is wind-blown.
