Product Details
Products Description
Galvanized Sheet Metal/ Stainless Steel Negative Pressure Fan
Negative pressure fan uses the cooling principle of air convection and the negative pressure air exchange, air is discharged to outdoor which makes the indoor air pressure drop, indoor air becomes thinner, forming a negative pressure zone, then outdoor air, due to the air pressure difference compensates into the room, so that the indoor stuffy gas can be quickly forced to dischargeoutdoor.
By this way,cooling effect can reach 90%-97%.Thus,negative pressure fan has the advantages of less investment, low energy consumption, significant cooling effect, etc.
Ruilin exhaust fan are widely used in Agriculture and industry ventilation and cooling. It is mainly used for factory workshop, animal husbandry, poultry house, livestock breeding, textile, greenhouse, etc.
