Stay Cool, Save Energy

By utilizing RTFANS's HVLS Fans, air coolers, and other systems, we can establish a comfortable indoor environment, enabling people to rest and work more effectively.

The cooling effect can reach 90%-97%.

The negative pressure fan(industrial exhaust fan) uses the cooling principle of air convection and negative pressure ventilation. Any poor ventilation problem with the industrial exhaust fan can improve the machine, and the cooling effect can reach 90%-97%.

The negative pressure fan has the characteristics of low investment cost, large air volume, low noise, low energy consumption, stable operation, long life, and high efficiency. The shutter automatically opens and closes to achieve a dust-proof, waterproof, and beautiful appearance; The best choice for modern workshop cooling and ventilation.

Ventilation and cooling

Because of the direct sunlight on buildings, machinery and equipment, the human body, and other heat sources, the workplace will continue to accumulate heat and keep the temperature high, while the negative pressure fan can quickly discharge the indoor hot air so that the indoor air pressure will drop to form a negative pressure space. The outside air is compensated to flow into the room. At the same time, the air activity takes away the heat accumulated in the room, which will also accelerate the evaporation of human sweat, and then make the human body feel cool.

Small investment and green environmental protection

The suction volume of the negative pressure fan is as high as 38,000 cubic meters, and the negative pressure fan does not use a compressor, which will not pollute the environment, and has low operating noise.

Simple operation and long use

The installation and operation of the negative pressure fan are very convenient and simple. The number of air changes is planned according to the actual needs of the space. Any high temperature, sultry, harmful gas, dust, and smoke can be quickly discharged from the workshop. Aluminum die-casting so can withstand high temperatures and is not easy to be deformed by aging so the fan can have a long service time.
