Metal Parallel Filter Element

Metal Parallel Filter Element is an industrial filter element consisting of multiple metal filter cartridges connected in parallel. It features high flow rate, low pressure drop, and is washable and regenerable. It is characterized by high flow rate and long service life and is widely used in industries such as hydraulic lubrication, petrochemicals, and power metallurgy.

Features

Extra-large filtration area: The parallel design provides 2-5 times the filtration area of a single cartridge of the same volume, resulting in high dirt holding capacity and long service life.
Low pressure drop, high flow rate: Parallel design minimizes flow resistance, making it suitable for high-viscosity/high-flow-rate fluids (such as lubricating oil and crude oil).
Washable and regenerable: The metal mesh can be repeatedly washed (ultrasonic/high-pressure water), with a lifespan 5-10 times that of paper filter cartridges, reducing costs.
High temperature and corrosion resistance: Stainless steel is suitable for harsh operating conditions such as high temperatures (≤450℃), acids, alkalis, and organic solvents.
High reliability: Single cartridge blockage can be replaced online, ensuring continuous system operation without system shutdown.
