The standard five-layer sintered mesh filter element uses a standard five-layer sintered mesh as the main filter material, customizable on demand. The standard five-layer sintered mesh is composed of five layers of stainless steel wire mesh laminated and vacuum sintered into an integrated structure, offering excellent corrosion resistance, good permeability, high mechanical strength, precise filtration accuracy, hygienic and clean material, and no wire shedding, as well as easy cleaning and backwashing. It is suitable for filtering lubricating oil and high-temperature corrosion-resistant liquids, with an operating temperature range of -200 to 650 °C and able to withstand high pressure of 0.1–30 MPa. Before delivery, products are cleaned by pickling, chemical polishing, and ultrasonic vibration to ensure cleanliness; after use, they can be regenerated via gas backflushing, high-pressure water jet, and ultrasonic cleaning to extend service life. Widely used in filtration of polyester, water treatment, oil products, pharmaceuticals, food & beverage, chemicals, fibers, and high-temperature air.
