Product Description

 

    

     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.

Our Advantages

     Negative pressure heavy hammer type is a more common, simple structure, more durable, like the remote control system is divided into mechanical version and intelligent version, because the mechanical version of the control is simple, so the failure is less.

      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.
