Medium efficiency filterIt can be used for intermediate filtration of air-conditioning system to protect the next-stage filter in the system and the system itself. In places where air purification and cleanliness are not strictly required, the air treated by the medium-efficiency filter can be directly sent to the user.

The aluminum frame bag-type medium-efficiency filter uses high-quality synthetic fiber or imported glass fiber as the filter material, aluminum alloy profile frame, and internal spray cold-drawn wire support frame.

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

2. If there is something blocking the surface of the medium-efficiency filter, it should be removed;

3. If the surface of the medium-efficiency filter material is severely damaged, it must be replaced with a new filter material or reinstalled with a new filter;

4. When installing the medium-efficiency filter, ensure a good seal between the blank holder and the frame to prevent air volume leakage;

5. Do not use heavy objects to hit the surface of the medium-efficiency filter, and do not use force to pull the surface of the filter material;

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

The medium-efficiency filter needs to be replaced within 3-4 months under the conditions of rated air volume; or when the resistance of the filter reaches more than 400Pa, the filter must be replaced; if the filter is used, it can be cleaned Type filter media, the replaced filter media can be rinsed with water or a solution containing neutral detergent, dried, and then replaced; cleaning is allowed at most two times, that is, a new filter must be replaced; such as in the use environment If the dust concentration is higher, the life cycle will be reduced.

The bag-type medium-efficiency filter can be used in the intermediate filtration of the air-conditioning system to protect the next-stage filter in the system and the system itself. In places where air purification and cleanliness are not strict, the air after the medium-efficiency filter can be used. Delivered directly to the user.

The aluminum frame bag-type medium-efficiency filter uses high-quality synthetic fiber or imported glass fiber as the filter material, aluminum alloy profile frame, and internal spray cold-drawn wire support frame.

The bag-type medium-efficiency filter, the frame has the form of cold plate sprayed, galvanized plate, etc. The filter material includes non-woven fabric, glass fiber, etc.

Bag-type medium-efficiency filters are widely used in central air-conditioning ventilation systems, pharmaceuticals, hospitals, electronics, food and other industrial purifications. They can also be used as front-end filters of high-efficiency air filters to reduce the load of high-efficiency air filters and extend their use life. Due to the large windward side of the bag filter, its dust holding capacity is large and the wind speed is low, and it is considered as a better medium-efficiency filter structure at present.

Bag-type medium-efficiency filters are mainly used in central air-conditioning and centralized air supply systems. They can be used in the intermediate filtration of air-conditioning systems to protect the next-level filters in the system and the system itself. In places where air purification and cleanliness are not strictly required, The air treated by the medium-efficiency filter can be directly sent to the user.
