Small kitchen fume purifier

Precautions for installing small kitchen fume purifiers:

Air leakage prevention measures must be taken at the joints of each air duct.To protect the infectious efficiency of the equipment.

The variable diameter air duct connected to the air inlet and outlet of the equipment should be as smooth as possible.To protect the infectious efficiency of the equipment.It is necessary to install a straight pipe with a length of more than 4 times the diameter of the pipe，and use a smooth pipe to connect.

Therefore，soft connections are required when connecting the air ducts of the light fan of the equipment.The equipment will not work normally if it is vibrated during operation.

To protect the infectious effect，the air volume of the individual fan is assumed to be greater than the designed air volume of the equipment.The equipment must work at the designed air volume.The user can control the fan with a frequency converter or install an air regulating valve device at the fan outlet to achieve this.

To reduce the additional resistance of the fan.It is better to keep a straight pipe section of 1-2 meters at the inlet of the fan.

The equipment should work in a negative air pressure state.To protect the infectious efficiency of the equipment.That is，the fan needs to be located in front of the equipment.

When the air is exhausted by a unified exhaust fan，when multiple devices are used in parallel.It is also necessary to ensure that the proportion of air volume allocated to each device is close to the proportion of air volume it intends to handle.

Rainproof and sunshade awnings should be installed when installed outdoors.Avoid affecting the normal operating life of the equipment and increasing unnecessary maintenance costs.
