Explosion Proof Centrifugal Fan

Industrial exhaust fan is a kind of exhaust fan, driven by an electric motor to drive the rotation of the fan blades to drive airflow, so that indoor and outdoor air exchange of a class of air conditioning appliances.

Ventilation principle

The process of exhausting air outward from the exhaust fan will cause the indoor air pressure to drop, and the indoor air will become thinner, forming a negative pressure zone, and the air will flow into the room due to the compensation of air pressure difference. In the actual application of industrial plants, exhaust fans are usually installed centrally on one side of the plant, the air inlet on the other side of the plant room, the air from the air inlet to the exhaust fan to form a convection blowing wind. In this process, the doors and windows near the exhaust fan remain closed, forcing the air to flow into the workshop from the inlet side of the doors and windows to compensate. Air flows into the workshop from the air inlet in a queue and in an orderly manner, flows through the workshop and is discharged from the workshop by the exhaust fan. The air exchange is thorough and efficient, and the air exchange rate can be as high as 99%. Through specific engineering design, design air exchange speed and wind speed as needed, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problem can be completely solved at once. The effect of ventilation can be achieved within a few seconds from the opening of the fan.

Cooling principle

The exhaust fan can quickly discharge the stuffy indoor air, and the air from the other side of the outdoor area will be inhaled into the room to achieve a temperature level with the outside world, so that the temperature in the workshop does not rise. The process of air flow will take away the body heat, air flow to accelerate the evaporation of sweat and absorb body heat, so that the human body feels cool, to achieve the same cool as the natural wind.
