Product Description

Core Advantages

1.Universal Quick-Install: Exclusive 3-ear structure fits most filter cartridge dust collectors, which is convenient and cost-effective.

2.High-Efficiency Precision Filtration: Replacement filter element with 1-7μm multi-precision options, 95%-99.9% filtration efficiency, delivering HEPA filter-level purification for diverse working conditions.

3.Versatile Functional Options:Available with filter media of flame-retardant/anti-static/oil-water proof functions to meet specific application requirements.

4.Durable Structure: Filter cartridge with galvanized mesh inner core and galvanized caps, ensuring rust and corrosion resistance while providing reliable protection and structural support.

5.Superior Sealing: Special rubber gasket and epoxy resin sealing keep leak-proof/cap-off resistant/powder-proof, ensuring filtration efficiency.

6.Customizable Specifications: Cylindrical/conical options; bottom cap style, filter media & filtration area can all be tailored to your needs.

Versatile Functions & Wide Applications

1.Flame-Retardant: For gas turbine power plants, gas turbine air intake systems, and industrial sites needing fire safety.

2.Anti-Static: For powder plants, powder coating plants, and dust collector filter elements – prevents dust buildup.

3.Oil-Water Proof: For central air conditioning, oxygen plants, steel mill oxygen blast stations, blast furnace air supply

stations, and other harsh conditions.

4.Standard Universal: No special functions, fits regular industrial dust removal scenarios - cost-effective option.
