Why choose the energy-efficient big exhaust fans?
Large air volume, power saving and good effect
The big exhaust fan uses negative pressure to change the air in the workshop/warehouse. Based on the logistics principle of air convection, the fan operation is to force the indoor high temperature gas, smoke, odor and dust out of the outside, and at the same time the outdoor fresh air will be introduced into the room. A 1.1 kW industrial extractor fan can cover a 100 square meter plant.
Wide range of applications
Big exhaust fans are suitable for a variety of workshops or industrial places, such as textile workshops, garment factories, injection molding factories, hardware factories and electronics factories.
Easy to install
The shape of the big exhaust fan is square, which is very convenient to install. Industrial ventilation fans are often installed on windows or walls and do not take up space. Since there is no need to install air ducts, the damage to the use environment of the negative pressure fan is also minimal.
Scope of use of big exhaust fan
Big exhaust fans are suitable for high temperature or odor workshops, such as heat treatment plants, casting factories, plastic factories, aluminum profile factories, shoe factories, electroplating plants and chemical plants.
Big exhaust fans are also suitable for workshops with dense workers, such as garment factories, assembly plants and assembly lines.
Industrial ventilation fan are also suitable for greenhouses, chicken coops, cowsheds, etc.
Cooling principle of big exhaust fan
When the ventilation system is not turned on, the temperature of the plant/warehouse is higher than the outdoor due to sunlight shining on the building, heat dissipation of machinery and human heat sources.
Normally, if the outdoor temperature is 32°C, the temperature inside the plant will reach 38°C when the fan is not turned on. After turning on the fan, the temperature in the plant can be cooled to about 32°C.
After big exhaust fans and evaporative cooling pads, the temperature in the plant can be cooled to 28-30°C. The perceived temperature reaches 27-29 ° C.

Industrial ventilation fan blades
The fan blades of industrial ventilation fans are available in three materials: galvanized, aluminum alloy and stainless steel.
The fan blades are one-time stamped and fastened with forged gas screws. The fan blades are precisely balanced and calibrated by the computer, which has the advantages of low noise, large air volume, stable and reliable operation.
Industrial exhaust fan motor
The motor adopts die-cast iron shell, and the protection level reaches a high level of IP54. The motor can be used continuously for 2400 hours without damage.
Push-pull open- close device
Shutter adopt special push-pull, open- close device, ensure shutter totally open and close, windproof, rainproof and dustproof.
Industrial exhaust fan impeller
The fan impeller is forged from aluminum alloy. The impeller is not easy to break and has a long service life.
A-type triangle belt
The fatigue resistance of the A-type triangle belt reaches 10^6 times.The fatigue resistance of the A-type V-belt reaches 10^6 times. The belt is characterized by high strength, low elongation and small length difference.
Greenhouse ventilation fan frequency converters
Frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motor by changing the frequency of the motor’s power supply.
For the regulation of wind speed, this kind of control equipment is also often used in greenhouse exhaust fans and other exhaust equipment.
