What is a medium filter?

What is a medium filter? Medium filters belong to the F class of all products, the efficiency levels of which are F5, F6, F7, F8, F9. Intermediate efficiency filter characteristics. Medium efficiency filters are first used as end filters for general HVAC systems and as pre-filters for filtering HVAC systems to filter ≥1μm dust from the air. Its filtration plays a role of ≥ fifty to ninety-nine percent (counting method) or the European norm F5-F9. The frame is an iron plate, and industrial aluminum; the filtering material is polypropylene and glass fiber filtering material. In the filter of this frame practice, the filtering material is made into a multi-bag type, which strengthens the area size of the filtering material and the air inlet, and reduces the obstruction of the air supply; it generally has the qualities of the tight frame, large air inlet, strong versatility, and quick installation. Medium efficiency filter working environment. Working temperature: minus ten degrees to eighty degrees, humidity: ≤ 80%, slightly acidic and slightly alkaline room gas filtration. Medium efficiency filter replacement deadline. In the standard air volume operating environment conditions, 2800 hours that need to replace the filter; if when the filter obstruction is much greater than four Pa above the moment, the filter should be replaced; such as the filter operation can be repeatedly used type filter materials, the replacement of the filter materials under the re-cleaning sun-drying operation again, that can reduce the cost of owners. The operation of the medium efficiency filter is important. Regularly check whether there is any debris blocking the air inlet surface of the filter and whether there is any damage to the appearance of the filter material; if items are blocking the appearance, they should be expelled; if the appearance of the filter material is damaged too much, the filter material should be replaced with new filter material or replaced with a new filter again; when the filter is installed, it should be ensured that the seal at the pressure edge of the frame is excellent to prevent air leakage; the filter should not be hit with heavy objects to the appearance of the filter When the filter is installed, the length of the filter bag should be perpendicular to the ground to ensure the filtering effect of the air supply and strengthen the operating life. Medium efficiency filters are first used in industrial ventilation systems for secondary or primary filtration to protect the latter filters in the system and the system itself and can be used in the first level of filtration at the end filters to reduce the burden on the end filters and enhance the service life of the end filters. It is often used in industrial filtration in pharmaceuticals, hospitals, photovoltaics, etc.
