G1 - G4 efficiency primary filters
G1 - G4 efficiency primary filtersThe primary filter is suitable for the primary filtration of air conditioning systems, mainly used for filtering dust particles above 5μm, the level from G1-G4, according to the specific gravity method primary filter G1 filtration efficiency of 40%; G2 filtration efficiency of 65%; G2 filtration efficiency of 80%; G4 filtration efficiency of 90%; generally, as the first layer of air purification, we will use the higher efficiency of G4, primary filter What are the advantages of g4 air filter?The primary filter material process is complete common practice: flat laying primary filter, folding primary filter, mother and father frame (keel type) primary filter, bag type primary filter. The outer frame of the primary filter material is made of galvanized frame, aluminum frame, paper frame, etc. The filter cotton is made of poly-fiber with superior performance, which is suitable for high-humidity occasions. In addition to the characteristics of the flat type, the folding process increases the filtering area and thus increases the dust capacity, which greatly improves the filtering efficiency. The subframe (keel type) primary g4 air filter also becomes washable primary air filter is supported by stainless steel or baking paint subframe, and the frame can be made of an aluminum profile frame or galvanized frame with a removable outer frame design, and the difference between the general primary filter is its repeated cleaning and replacement, which saves the use cost to a large extent. The G4 bag filter is available with a galvanized frame and an aluminum frame. Each filter bag is fixed with a metal strip to increase the strength of the filter bag and at the same time to ensure even airflow and to prevent the bag from breaking due to the friction of wind cutting at high wind speeds. It has a high dust-catching capacity, high dust-carrying capacity, and high air permeability for long service life. |
