Livestock exhaust fan outside the indoor air pressure falls, indoor air becomes thinner, livestock fan features form a negative pressure zone, air flows into the interior of compensation due to the pressure difference. In practical applications, industrial plants, livestock fan installed in the plant to focus on one side, the air intake to the plant room on the other side, the air from the intake port to livestock fan convection hair. In this process, the fan near the doors and windows remain closed Livestock Husbandry unique fan motor hole wind deflector to prevent wind erosion, wind set to achieve the best results aerospace aluminum alloy wheels, light weight, high strength, exhaust fan, toughness Well, not broken; livestock fan Main structure: mainly by the fan blower, motor, frame, grille, cage, blinds and other components, motor-driven fan produces airflow, venetian blinds type according to user needs with the boot after Shutters can automatically open the shutters closed automatically shutdown to prevent dust from entering, but also avoid the impact of rain and snow and wind down. A roof fan dust: roof fan is rotated 24 hours non-stop, easy attachment of dust, do not need cleaning. 2, light weight: light weight roof fan, very light and strong, in the design and planning of the plant structure, the roof does not need to worry about heavy load. 3, light: there is a gap between the blade and the blade into the interior light will thus be increased illumination. 4, zero failures: a strict ball shape of the structure, the upper and lower permanently lubricated ball bearings ensure long life, no maintenance, no need to replace parts, 5, rain characteristics: the design is absolutely waterproof, it has a turbine blade, while the blade is rotated by centrifugal force, the indoor air is discharged into the rain barrier, and between the blade and the blade due to rapid rotation of the exhaust fan where the sale, each sheet is formed to fill the gap, even when attached to the blade of a small Raindrops can also flow along the blade roof. Therefore, the turbine ventilation is the best waterproof 6, operating system: the use of high-precision bearing system fully enclosed, highly heat-resistant synthetic bearing grease is the best lubricant permanently self-lubricating, no maintenance, even if the wind speed In less than two kilometers of the breeze under exhaust fan specifications, but also self-running 7, solid: structural design can be bent with a thread groove rolling rain leaves one piece and able to withstand the speed 200km / h in strong winds attack, is the most robust turbine ventilators. 8, anti-corrosion: Use GB 304 # stainless steel, resistant to strong acids, strong resistance to seal exhaust fan where the good, but also resistant to corrosion, material using the best materials ventilation equipment. 9, to prevent noise: the use of wind-driven principle, not the use of motor power, cost-free electricity-free operation, the turbine ventilators stop self rotation, so silent no noise when running.
