Clean Room Medium Efficiency Air Filter

Efficiency: F5, F6, F7, F8, F9

Features: The filter material is made of synthetic fiber composite filter material or extremely fine glass fiber;

Application: Widely used in pharmaceutical, hospital, electronic semiconductor, precision machinery, food and other industries.

Conventional sign

F5, F6, F7, F8, F9 are filtration efficiency (colorimetric method)

F5：40~50%；

F6：60~70%；

F7：75~85%；

F8：85~95%；

F9：99%

Application

1.    Mainly used in central air conditioning ventilation system intermediate filtration, pharmaceutical, hospital, electronics, food, and other industrial purification;

2.    It can also be used as the front-end filter of high efficiency HEPA filter to reduce the load of high efficiency filtration and extend its service life;

3.    Due to the large windward surface, the amount of air dust is large, the wind speed is low, and it is considered to be the best medium efficiency filter structure.

Features

1.      capture 1-5μm of particulate dust and a variety of suspended matter.

2.      the use of hot melt process, stable structure, reduce the risk of breaking and leaking.

3.      large air volume.

4.      low resistance.

5.      high dust capacity.

6.      can be used for repeated cleaning.

7.      type: frameless and framed bag type.

8.      filter material: special non-woven fabric or glass fiber.

9.      efficiency: 60% ~ 95%@1 ~ 5μm (colorimetric method).

10.   maximum using temperature, humidity: 80℃, 80%

Replacement period

1.    Under the conditions of rated air volume, the filter needs to be replaced in 3 to 4 months;

2.    Or when the resistance of the filter reaches more than 400Pa, the filter must be replaced;

3.    If the filter uses washable filter material, the filter material under replacement can be washed with water or a solution containing neutral detergent, cool and dry, and then replaced; A maximum of two cleaning times is allowed, that is, a new filter must be replaced;

4.    If the dust concentration in the use environment is large, this service life cycle will also be reduced.

Matters need attention

1.    Regularly check whether the filter inlet air surface is blocked by debris and whether the filter material surface is damaged.

2.    If there are objects blocking the surface, remove them.

3.    If the surface of the filter material is seriously damaged, it is necessary to replace the new filter material or replace the new filter and reinstall it.

4.    When the filter is installed, it is necessary to ensure that the seal is good at the press edge of the frame to prevent air leakage.

5.    Do not use heavy objects to impact the surface of the filter, do not force to pull the filter material surface of the filter.

6.    When installing, the length direction of the filter bag mouth should be perpendicular to the ground to ensure the filtration effect of the air supply and increase the service life.
