The medium efficiency plate filter has a lower filtering accuracy than the high efficiency filter, but it can also be directly used in the wind room and ventilation and air conditioning equipment with less strict purification requirements. When using the medium efficiency plate filter, it is necessary to regularly check the air resistance. The high air resistance value indicates that the dust content of the filter is high. In addition, the dust content in the surrounding environment will directly affect the service life of the plate filter. In order to better extend the service life of the medium efficiency filter, it is necessary to regularly clean the floor and wall in the wind room and keep it clean.
Characteristics of medium efficiency plate filter:
1. The outer frame is firm and removable: the solid plate aluminum alloy frame is used, with aluminum alloy corners or plastic corners. The structure is firm and stable to ensure that the filter will not be deformed or damaged under poor working conditions. The outer frame is designed to be removable to facilitate the replacement of filter materials to achieve the purpose of frame reuse and save costs.
2. Light plate structure, simple handling and installation, high-quality polyester synthetic fiber filter material, low initial resistance, high dust capacity.
3. The medium efficiency plate filter will generally increase the stiffeners, further enhance the robustness of the filter, and the balanced spacing and double stiffener design will ensure the equal height pleats of the filter screen, so that the filter can achieve a large dust capacity when the resistance is small. The filter material is fixed with diagonal lines at the front and back of the outer frame. The filter material and the outer frame are tightly bonded to prevent any air leakage. The filter area is 2-5 times of the general plane.
4. The filter material is made of polyester synthetic fiber with good quality, which can be cleaned and reused for many times, has a long service life and a fluffy and gradually dense fiber structure, ensures a high dust collection rate and a large dust holding capacity, prolongs the service life of the rear high-efficiency filter, and reduces the operating cost.
5. There are 1 inch (21, 25 mm), 2 inch (46 mm), 4 inch (96 mm) different thicknesses available, 1 inch flat structure, 2 inch and 4 inch pleated structure.
6. Filter grade can be selected: F5 (EN779), F6, F7, F8, F9.

7. Conform to the fire classification standard DIN53438-F1 in Europe and UL900-CLASS2 in the United States.
