E-MAIL:whf@zjhfhb.com| Negative pressure fan: it is the use of air convection, negative pressure ventilation principle of ventilation to super suction, the indoor air quickly pumping out of the outdoor, so that the formation of indoor negative pressure. At the same time by the installation of the location of the door, door or window suction fresh air, so constantly replace fresh air. After the use of negative pressure fan, you can let the air flow up, the number of times per hour ventilation can reach 60 times -120, any ventilation problems can be solved. Cooling ventilation effect up to 90%-97%. Currently on the market as well as the working principle of a negative pressure fan is such that the negative pressure zone is formed in the inner part of the fan, and then because of negative pressure, air will be sent to the room, to achieve ideal effect of negative pressure fan positive pressure ventilation. The negative pressure ventilation system: refers to the pig in a wind curtain, leaving only a large enough air inlet, and then start the suction fan, to achieve the ideal ventilation effect. Mainly applicable to high temperature or peculiar smell workshop, labor-intensive enterprises, horticultural greenhouse ventilation cooling, livestock farm cooling, plastic injection molding, metal die-casting, textile clothing, electroplating, footwear and other industrial workshops. |
