Compared with the traditional exhaust fan, the negative pressure fan has obvious advantages:

(1) Convenient: Manual shutter control enables normal lighting and ventilation when no fan is needed.

(2) Low input: large exhaust capacity of single machine, wide application range. At the same temperature, the project has a high cost performance ratio.

(3) Environment friendly: no compressor, no refrigerant, less pollution and low noise.

(4) Easy to clean: continuously provide fresh and clean air for the workshop, and increase the oxygen content in the air.

(5) Easy maintenance: easy to install, less maintenance, easy to operate, no professional maintenance required.

(6) Durable: heavy aluminum die cast blades, high temperature resistance, aging resistance, and no deformation.

Ventilating windows are also called breathing windows and ventilation windows. According to the principle of atmospheric flow mechanics, mechanical exhaust and negative pressure air inlet are adopted. Without opening the windows, indoor dirty air can be quickly discharged from the outside, and outdoor fresh air can enter the room naturally after being purified, forming indoor and outdoor air flow and exchange, and maintaining the air quality of indoor space.

Four Advantages of Glass Fiber Reinforced Plastic Negative Pressure Fan

A Reduce temperature and increase oxygen content

Each fan delivers 2375-20356 cubic meters of air to the plant every hour, 20356-55000, for indoor and outdoor air exchange, that is, at least once a minute for indoor fresh air exchange.

B Power saving (reducing company operating costs)

Based on the principles of fluid mechanics (airflow), the optimized design of ladle-shaped blades, coupled with a patented speaker type cover, enables the fan to generate high exhaust air volume when operating at low speeds. It is currently the best cooling device on the market with the least power consumption, requiring only 0.75 kw per hour.

C Mute

The fan blades, pulleys, and bearing sets are balanced and corrected using a vector display type power balancer to ensure smooth and noise free operation of the fan.

The fixed base for fan operation is processed by computer CNC and sealed and fixed with TPI bearings, making the fan operation less prone to noise.

3. The multi v belt with the best performance and effect in the automotive field is used as the rotating belt of the fan, which is not prone to slipping and generating noise.

Yongyuan motor produced with advanced technology from Taiwan, with insulated aluminum housing, has long service life, stable operation, and low noise.

The fan is made of FRP (glass fiber reinforced plastic) processed from glass fiber and imported resin, which has excellent sound attenuation function, waterproof and dustproof, and reduces resonance due to excessive metal materials in the entire machine.
