The positive pressure fan is a new type of ventilation axial fan used in pig house.
The positive pressure fan is a new type of ventilation axial fan used in pig house. With the dense cloth cover and PVC pipe, fresh air can be pressed into the PVC pipe through the cloth cover, through the pipe to achieve long distance air supply to the pig house, through the PVC pipe facing up the exhaust hole from the upper part of the pig house, in the process of slowly falling with the original hot air in the pig house heat exchange, so that when the fresh air reaches the surface of the pig body, it will not dry to cause cold stress to the pig. Fiberglass shell is extremely strong and resistant to corrosion, no deformation, no fading; The flared vent is highly impact-resistant, improving the performance by 10%; High strength nylon fan blade, can effectively reduce vibration and increase air flow, improve efficiency; Optional butterfly valve can effectively prevent return air; High efficiency motors such as Siemens and Dongyuan are available.
