What is the basic knowledge of medium – effect bag filter?
1. Medium effect bag filter features:
It is mainly used as the final filter of general air conditioning system and the pre-filter of purifying air conditioning system to filter the ≥1μm particle dust in the atmosphere. Its filtration efficiency ≥50%~~99%@≥1μm (counting method) or European standard F5 — F9. The outer frame is: galvanized sheet, aluminum profile; Filter media: polypropylene fiber and glass fiber materials. The structure of the filter(air filter Manufacturer), filter material made into multi-bag type, increase the filter material area and air supply volume, reduce the resistance of air supply; It has the advantages of compact structure, large air supply, strong versatility and easy installation.
2. Medium effect bag filter applicable conditions:
Temperature: -10~ 80℃, humidity: ≤80%, slightly acidic and alkaline air filtration
Please refer to this website for model size and parameters.
3, medium effect bag filter replacement period:
Under the conditions of rated air volume, the filter needs to be replaced in 3-4 months; Or when the resistance of the air filter reaches more than 400Pa, the filter must be replaced; If the filter uses washable filter material, the filter material can be replaced with clean water or a solution containing neutral detergent to wash, cool and dry, and then replaced; Cleaning is allowed two times at most, that is, a new filter must be replaced; If the dust concentration in the environment is large, the service life cycle will be reduced.
4. Note on the use of medium effect pocket bag air filter:
Regularly check whether the filter air inlet surface is blocked by debris, filter material surface is damaged; If there are objects blocking the surface, remove them; Filter material surface damage is serious, must replace the new filter material or replace a new filter to reinstall; When the filter is installed, it is necessary to ensure that the sealing of the pressing part of the frame body is good to prevent air leakage; Do not use heavy objects to impact the filter surface, do not force to pull the filter material surface; During installation, the length direction of the filter bag mouth should be perpendicular to the ground to ensure the filtering effect of air supply and increase the service life.
5. Medium effect bag filter technical parameters:
Aluminum frame bag filter adopts high quality synthetic fiber or imported glass fiber as filter material, aluminum alloy profile outer frame, internal spray cold-drawn wire support frame.
Bag filter has large effective filtering area, large dust capacity, small resistance and large ventilation capacity; The frame and the support frame can be reused, and the filter bag only needs to be replaced when the filter is replaced, which is convenient and fast, and greatly reduces the operating cost. Widely used in electronics, pharmaceutical, medical, food and other industries, is the best structure of the filter system.
Efficiency specifications: G4, F5, F6, F7, F8, etc.
