Product performance description

     The Greenhouse Exhaust fan is popular in recent years.The Greenhouse Exhaust fan is a new environmentally friendly and
energy-saving plant ventilation cooling equipment, because of the exhaust fan's large amount of ventilation, ventilation and cooling effect is good, low noise, the installation of the use of the site of the smallest destructive, cheap to buy, wide range of applications, Long life and other significant features, more and more users are loved.

     Product usage introduction

     Using the air convection, the principle to design of negative pressure ventilation. In poorly ventilated places, normal work,using mechanical kinetic energy causes the fan operation.Will the smell of indoor heat, lampblack, stand in the shortest time quickly send out.At the same time, the outdoor fresh air and indoor ventilation and cooling circulation exchange, so as to achieve the
purpose of improving the indoor air environment.

Fan blade
       Fan blade is made of stainless steel, which is dust-free, beautifu and durable.Special blade shape design ensures high air volume, no eformation, no fracture, so that the air volume is the
same all the way.









Motor 
   Both Chinese famous motor and Siemens motor are avalable, Motor voltage and frequency could be customized.Chinese famous motor, special design for fan, the first one put forward the phase lack protection device which could power off when shortage of electricity. Motor protection grade IP55, insulation Class: Grade F

Fan belt pulley
      Fan belt pulley is die-cast from high strength aluminum magnesium alloy, reducing weight, complete impeller blades, and high corrosion resistance.Reinforcement pulley design.Eliminate internal stress, improve
its own stiffness and stability, will not break





Fan bearing
      Fan bearing adopts imported double-row bearing with special waterproof design,water can't enter.High strength,lower noise,maintenance free and long service life.




Heavy hammer
     Using high strength nylon swung drop hammer opening device to ensure
the shutters and closing flexible.

      Heavy hammer type negative pressure fan is widely used in shopping malls, factories, warehouses, factories, greenhouses, flower planting, breeding and other places that need ventilation.
      Using the air convection, the principle to design of negative pressure ventilation. In poorly ventilated places, normal work, using mechanical kinetic energy causes the fan operation.
      Will indoor heat, the smell, lampblack, standing still in the shortest possible time emitted quickly, at the same time the outdoor fresh air and indoor ventilation cooling circulation exchange so as to achieve the purpose of improving indoor air environment.
