• Sturdy and removable outer frame: the sturdy aluminum alloy frame is used, fixed with aluminum alloy corners, which has a sturdy and stable structure and ensures that the filter will not be deformed or damaged under poor working conditions, and the outer frame is chosen to be removable to facilitate replacement of the filter material for the purpose of frame reuse; the filter mesh is made of special reinforcement bars to further enhance the sturdiness of the filter.

• The filter mesh is made of special reinforcement, which further enhances the sturdiness of the filter. Together with the balanced spacing and double reinforcement planning to ensure that the filter mesh is of equal pleat shape, so that the filter can achieve the dust capacity at the time of minimum resistance.

• The filter media is made of high-quality polyester synthetic fiber, which can be washed and reused repeatedly and has a long service life. The fluffy and gradually dense fiber structure ensures a high dust collection rate and a large dust capacity, which effectively prolongs the service life of its back-end intermediate-effect filter.

• Filtration efficiency grade: G1, G2, G3, G4 (EN779).

• Coarse, medium, high, medium and high efficiency, sub-high efficiency, high efficiency, ultra-high efficiency 6 kinds of filters have their own purposes, must be used correctly, if not used properly, not only will not work but also produce bad or even the opposite effect. Therefore, the design, construction and maintenance management of cleanrooms should pay special attention to the personnel.

• Coarse filter is used as a pre-filter, generally set up in the air conditioning box, its role is to filter large particles of particles, in order to protect the subsequent air conditioning equipment (such as the table cooler and heater, etc.) and intermediate as well as more advanced filters. Generally coarse-effect filters cannot be used as terminal filters.

• Medium-effect filter is generally located in the positive pressure section of the air conditioning box, and its role is to protect the sub-high-efficiency, high-efficiency filters and other terminal filters. It removes small and medium-sized particles ≥ 1.0µm. Generally, the intermediate filter is an intermediate filter, which can not be used as a pre-filter, nor can it be used as a terminal filter.

• High-efficiency and ultra-high-efficiency filters are used as terminal filters in purification systems. They are generally placed on the ceiling of the clean room. High-efficiency filters (HEPA) are the necessary terminal filters for cleanrooms. Ultra-high-efficiency filters are 0.1µm, class 10, class 1 or higher level cleanrooms must have terminal filters.
