The oil filter of the screw air compressor is the core component of the lubrication system, used to filter metal debris, impurities, and oxidation products in the lubricating oil, preventing them from entering the internal wear parts of the main engine. It usually uses high-precision filter materials with pressure and temperature resistance characteristics, and is equipped with sealing rings to ensure filtering effect. It needs to be replaced regularly to maintain stable operation of the air compressor and extend equipment life.

The oil filter element of the screw pump is the "purification guardian" of the lubrication system, installed at key nodes of the oil circuit (such as the inlet and return pipe). Intercept metal debris, oxidized gum and other impurities (with an accuracy of 5-30 μ m) through multi-layer filters to prevent wear on the rotor and bearings. High temperature/high pressure resistant materials are suitable for working conditions, ensuring stable equipment operation and extending service life.

The initial folding filter adopts a high pleated filter material design, and the non-woven/synthetic material is made into a V-shaped three-dimensional structure through mechanical folding technology. The filtration area is increased by 3-5 times, and it has both low wind resistance and high dust holding characteristics. It is suitable for air conditioning pre filtration, industrial dust removal, and clean workshops, and can intercept particles ≥ 5 μ m, which is easy to maintain and cost-effective.

The new DFB series high-pressure plate filter is designed specifically for high-pressure hydraulic systems and can be directly stacked and installed under the valve block to intercept pollutants such as metal particles and gum. Its nominal pressure reaches 32MPa, with a filtration accuracy of 3~30 μ m and an efficiency of ≥ 99.5%. It is equipped with a pressure differential signaling device and a bypass valve to ensure the safe operation of the system.

The CFFA series self sealing magnetic oil suction filter is a filtering device used in hydraulic systems. It is equipped with high-strength permanent magnets to adsorb ferromagnetic impurities, and the filter element filters non ferromagnetic particles. It is equipped with a manual self sealing valve, which can be closed when replacing the filter element to prevent oil leakage. It also has a blockage transmitter, which can prompt maintenance in a timely manner.

The excavator oil filter is the "heart guard" of the engine lubrication system, which intercepts metal debris, carbides, colloids and other impurities in the engine oil through multiple layers of filter materials (such as fiber filter paper and metal mesh) to ensure that the cleanliness of the engine oil meets the standard. It is suitable for models ranging from 5 to 100 tons, with vertical/horizontal installation design adapted to different engine layouts, and needs to be replaced regularly every 250-500 hours. The filter element is equipped with a bypass valve to prevent oil shortage and dry wear, and the sealing ring is coated with oil to prevent leakage. It is a key component to ensure the long-term operation of the engine and reduce abnormal wear of components.

The installation of sintered filter cartridges should comprehensively consider the characteristics of the medium, operating parameters, and equipment structure. Standardized interfaces (such as threads and clamps) should be prioritized to reduce the risk of leakage. In special operating conditions, modular or suspended design should be adopted. After installation, it is necessary to conduct sealing verification and establish maintenance records to optimize the lifespan of the filter element.

The magnetic flip level gauge uses magnetic coupling to drive the flip plate to achieve passive liquid level display. The red and white dual color interface is clear and intuitive, and has strong anti-interference ability. The fully sealed structure eliminates the risk of medium leakage, and it is resistant to high temperature and high pressure (450 ℃/32MPa) and strong corrosion (compatible with 316L/PTFE lining). It supports explosion-proof certification and can expand 4-20mA signal output or wireless remote transmission function, realizing dual-mode operation of on-site visual and remote monitoring. It is flexible to install (side mounted/top mounted) and has low maintenance cost, with high reliability and economy. It is widely used in complex working conditions such as petrochemicals, energy and power, and hazardous chemical storage and transportation.

The composite filter element of an air purifier is a core component that integrates multiple purification technologies. It intercepts hair/large particles through the primary filter layer, filters PM2.5/pollen/bacteria through the HEPA filter, adsorbs formaldehyde/odors through the activated carbon layer, and decomposes harmful gases through the catalytic layer, achieving multiple effects with one core. Its advantages lie in efficient purification (filtration rate ≥ 99%), extended filter life (partial pressure anti clogging), and adaptability to complex pollution scenarios, especially suitable for use in newly renovated houses, mother and baby households, and areas with high haze incidence.

The coagulation oil-water separation filter element is a core component designed specifically for oil-water separation, achieving efficient separation through physical coagulation and precision filtration technology. Its core structure consists of a coalescence filter element and a separation filter element, which work together to complete the oil-water separation process.
