Product description
Sintered porous metal filter cartridges for permanent industrial filtration
Porous metal filter cartridges are precision-engineered sintered filter elements designed for long-term industrial gas and liquid filtration. Manufactured from powder metal and formed into rigid cylindrical elements, these cartridges provide uniform pore structure, high mechanical strength and reliable contaminant retention.
These cartridges are designed for permanent filtration installations and can be cleaned in situ using blowback (gas systems) or backwash/backflush systems (liquid systems), significantly extending service life compared to disposable filters.
Construction and design
Porous metal filter cartridges are available in rolled and welded (Series 2200) or seamless (Series 2300) constructions. Standard diameters range from small seamless tube elements to larger rolled and welded configurations.
Cartridges are available in double open-end gasket sealed configurations and can be supplied with welded hardware, threaded fittings or flange mounting options.
Standard nominal lengths: 10", 20", 30"
Custom lengths up to 70" available
Standard diameter configurations from 3/8" to 4"
Multiple connection and mounting styles available
Material options
Porous metal filter cartridges can be manufactured from a wide range of corrosion-resistant and high-performance alloys:
316L Stainless Steel – general industrial applications
904L Stainless Steel – enhanced chloride resistance
Nickel 200 – hydrogen and caustic service
Monel 400 – marine and brine environments
Inconel 600 – high temperature oxidation resistance
Hastelloy C-276 – aggressive chemical resistance
Hastelloy C-22 – superior pitting and crevice resistance
Hastelloy X – high temperature structural stability
Material selection depends on process chemistry, temperature and operating pressure.
Available micron ratings
Porous metal cartridges are available in media grades suitable for liquid/solid and gas/solid separation:
0.2 micron
0.5 micron
1 micron
2 micron
5 micron
10 micron
20 micron
40 micron
60 micron
100 micron
Pressure performance
Standard differential pressure ratings:
Outside-in: up to 50 psi (standard construction)
Inside-out: up to 40 psi
Spring-reinforced versions are available for higher pressure applications:
Outside-in: up to 250 psi (media grades 0.2–40)
Outside-in: up to 150 psi (media grade 100)
Custom high differential pressure designs exceeding 3000 psi are available upon request.
High temperature capability
Maximum operating temperatures depend on material and atmosphere. For example:
316L stainless steel: up to 750°F (oxidizing), 1000°F (neutral/reducing)
Inconel 600: up to 1100°F (oxidizing), 1500°F (neutral/reducing)
Hastelloy X: up to 1450°F (oxidizing), 1700°F (neutral/reducing)
Typical applications
Gas/solids separation
Liquid/solids filtration
Catalyst retention and recovery
High-temperature process gas filtration
Chemical and petrochemical processing
Food and beverage clarification
Power generation condensate polishing
Pollution control and stack gas sampling
Cleaning and reuse
Porous metal cartridges are fully cleanable using backwash, blowback, ultrasonic cleaning, chemical cleaning or controlled thermal cleaning. Properly maintained cartridges can remain in service for years, reducing lifecycle costs compared to disposable elements.
