Core Technology

Industrial Exhaust Fan Featurer

Belt

V-Type belt adopts the USA Gates belt, lifespan is 3 times of average belt. To check whether the degree of tightness is right or not can be examined by the forefinger and middle finger pressing the middle of the belt, 15-20mm's down-pressing is suitable.

Industrial Exhaust Fan Featurer

Bearing

High-quality and three threes guarantees.
Central bearing is coming from imported overseas.

Industrial Exhaust Fan Featurer

Casting

RTFANS'S exhaust fans are made of the FRP material which is acid and alkali resistant, by 800 tons of molding, and never is fractured. The products could be used in any environment for 30 to 50 years, and cabinet guarantee for 20 years.

Industrial Exhaust Fan Featurer

Shutter

Opening-closing of shutter adopts a new European patented structure to avoid failure of opening and closing as being used a period of time.

Industrial Exhaust Fan Featurer

Fan Blade

RTFANS blade adopts acid-resistant & alkali-resistant & never-broken material, through scientific curve-designing, it has larger airflow and lowers windage.
Airflow 1/3 larger than the ordinary fan, noise 10 dB lower, With characteristics of anti-aging, high intensity, long service life.

Industrial Exhaust Fan Featurer

Motor

RTFANS motor adopts scientific energy-saving design, has protector made-in-USA inside, which can automatically protect against open-phase, over-flowing, over-loading.
Save operation costs 20%-30%, RTFANS motor adopts scientific energy-saving design (Siemens Technology), and choose high-permeability silicon steel sheet, which reduces useless energy greatly and enhances the ratio of electrical power converted into mechanical energy.

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.

Safety First Industry Standard

Compared with other brands of large HVLS fans on the market, all the fans we produce have passed the high-strength crash test, the fans will not fall off, and the blades will not break.
Just like our manufacturing requirements, protecting people, products, and property from harm is our number one priority, so our HVLS fans are not responsible in the event of an accident or emergency.

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 it can withstand high temperature and is not easy to be deformed by aging so that the fan can have a long service time.
