Glass fiber reinforced plastic gathering ram fan performance characteristics:

Working principle of the negative pressure fan: suction fan is to use air convection, the principle of negative pressure ventilation design, suction fan is installed in a poorly ventilated place, normal work, using negative pressure workshop heat, peculiar smell, lampblack, standing still in the shortest possible time quickly ruled out outside, at the same time bring fresh air into the indoor, outdoor and rapidly pull in the indoor air, so as to achieve the purpose of the ventilation and cooling to improve the workshop environment;

In pieces this product low noise, steady operation, large air volume

Pieces of negative pressure type bell mouth fan, fan for direct type free maintenance without belt replacement maintenance

Shutter design by using the principle of the air downstream, don't need to use electricity and personnel closed, can prevent the rain intrusion;
