Precision filters are equipped with wire-wound honeycomb cartridge or meltblown cartridge inside, which are used for filtration of production water, alcohol filtration, acid and alkali filtration, and security filtration before reverse osmosis RO membrane in drinking water, domestic water, electronics, printing and dyeing, textile and environmental protection industries, with large flux, low cost of consumables, polished or matte appearance, and acid-washing and passivation treatment of the inner surface. Precision precision filter is for the filtration precision, generally between sand filtration (coarse filtration) and ultrafiltration Precision filter features: high filtration precision, uniform pore size of the filter element; small filtration resistance, large flux, strong dirt-trapping capacity, long service life; high cleanliness of the filter element material, no pollution of the filtration medium; resistance to chemical solvents, such as acid, alkali, etc.; high strength, high temperature resistance, the filter element is not easy to be deformed; low price, low running cost, easy to clean, and the filter element can be replaced. Low price, low running cost, easy to clean, replaceable filter element. The filter element of BETEN high-efficiency precision filter adopts straight-through open design, so that the filtered impurities go straight through the liquid storage chamber without penetrating through the filter element and are discharged through the automatic drainage valve; the central filter element adopts high-quality polymer filter material, which has certain adsorption capacity for impurities such as oil mist and fully ensures the filtration effect; part of the compressed air is blown from the top to the bottom of the inner wall of the filter element, so as to effectively exclude the filtered impurities and at the same time reduce the resistance of the filter element to the compressed air. Reduce the resistance of the filter element to compressed air. Bei Teng High-Efficiency Precision Filter (High-Efficiency Precision Filter) is mainly used for the filtration of solid particles impurities in compressed air and has a certain blocking effect on liquid water and oil, which changes the structure and filtration method of traditional filters. Recommended Senjie environmental protection it, the quality of this brand is better, and the efficiency is also better.
