Five factors affecting fan selection:

1. Air volume and pressure

2. Operating conditions

3. Exhaust gas composition

4. Installation position and installation form

5. Accessories, noise and other requirements.

On different occasions, what is the difference between the selection of the fan?

1. Need to exhaust heat or exhaust steam, should try to set the roof exhaust fan priority.

2. When heating, cooling or fresh air is needed, the heating flow or cold air flow should be allowed to flow through the location of the staff as much as possible, so the pipeline fan or side wall fan should be used more.

3. Fire smoke exhaust, should give priority to the roof fan or hoisting duct, so choose more pipe fan.

Note: make full use of natural air flow (fan position and form should be set reasonably) fan selection for specific occasions

1. Warehouse ventilation

(1) to see whether the storage goods are flammable and explosive goods, such as: paint warehouse, etc., must choose explosion-proof series fan.

(2) to see the noise requirements, you can choose the roof fan or environmental protection centrifugal fan.

(3) Look at the size of the air ventilation required for the warehouse air, you can choose the regular axial fan SF type or exhaust fan FA type.

2. Kitchen exhaust

(1) For the kitchen with indoor direct exhaust fume (that is, the exhaust outlet is on the indoor wall), SF type axial flow fan or FA type exhaust fan can be selected according to the size of the fume.

(2) For kitchens with large oil fume and oil fume that needs to pass through long pipes and have bending treatment in the pipes, it is strongly recommended to use centrifugal fans (4-72 centrifugal fans are universal, and 11-62 low-noise environment-friendly centrifugal fans are also very practical). This is because the pressure of centrifugal fans is higher than that of axial fans, and oil fume does not pass through the motor, making it easier to maintain and change the motor.

(3) it is suggested that the kitchen with strong lampblack should use the above two schemes, and the effect is better.

3. Place ventilation. For hotels, tea houses, coffee bars, chess and card rooms, karaoke halls and other places to ventilate, it is not suitable to use regular fans.

(1) For the ventilation of small rooms, the room where the ventilation pipe is connected to the central ventilation pipe can choose a small axial flow fan on the basis of taking into account the appearance and noise, with small volume, plastic or aluminum appearance, low noise and high air volume.

(2) wind and noise requirements more stringent point of view, the fan box is a good choice. There are silencing cotton inside the box, and the remarkable effect of noise reduction can be achieved after the external central ventilation duct.

(3) Like the indoor blower in the gym, the industrial electric fan with large air volume must be selected instead of the SF-type post-type axial flow fan. This is from the appearance and safety considerations.
