FSD-FA Series

Ventilation fans work with the cooling principle of air circulation and negative pressure. It is a machine that naturally inhales fresh air from the opposite direction (door or window) of the installation site, and quickly forces the indoor muggy gas out of the room. Any poor ventilation problems can be improved. The cooling and ventilation effect can reach 90% - 97%.

Ventilation fans draw out the air through the rotation of the fan blades, so that the indoor air pressure drops, and the indoor air becomes thinner, forming a negative pressure area. The air flows into the room due to the compensation of the air pressure difference. In the practical application of industrial plants, ventilation fans are centrally installed on one side of the plant, the air inlet is on the other side of the plant, and the air forms convective blowing from the air inlet to the negative pressure air phase.

In this process, the doors and windows close to ventilation fans remain closed, and the forced air flows into the workshop through the compensation of the doors and windows on the side of the air inlet. The air flows into the workshop in an orderly manner from the air inlet, flows through the workshop, and is discharged from the workshop by ventilation fans. Through specific engineering design, design the ventilation speed and wind speed as required, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problems can be completely solved at one time. The ventilation effect can be achieved within a few seconds after starting the fan.
