Product Description
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 discharge outdoor.
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.
The FRP negative pressure fan is a new type of ventilation equipment made of anti-corrosion FRP material, which belongs to the axial flow fan, the outer frame of the fan is made of anti-corrosion FRP material. The FRP negative pressure fan is suitable for almost all places that need cooling or ventilation, especially for places with acid and alkali corrosion, high temperature or odour workshops, such as chemical, petroleum, metallurgy, mining, machinery, etc.

Our Advantages
The FRP negative pressure fan under Ruilin products has the following advantages:
1. Strong corrosion resistance: SMC FRP has good corrosion resistance to acid, dilute alkali, salt, organic solvents, seawater, etc., and can be operated in some specific environments.
2. Light weight and high lightness: specific strength and specific modulus are one of the indicators to measure the bearing capacity of the material, the relative density of FRP is only 1/4~1/5 of carbon steel, but the strength can be compared with senior alloy steel.
3. Good electrical properties: FRP is an excellent insulating material, can still protect good dielectric properties under high frequency, and is not subject to electromagnetic effects and does not reflect electromagnetic waves.
4. Low thermal conductivity: FRP is an excellent insulation material, ideal for thermal protection and ablation resistance, and the thermal stress generated when there is a temperature difference is much smaller than that of metal.
5. Long service life: Rui Lin FRP negative pressure fan, with pure copper core protection motor, anti-corrosion and rust bracket, anti-corrosion and rust louvers, anti-corrosion and rust protection net, is strong, durable and reliable, and can last for a long time.
