Key characteristics - Configuration: Miniature T-type filters ("Mini-T") - Typical use: Protection of test equipment, valves, gauges and instrumentation - Element style: Pleated elements, typically stainless steel wire mesh - Operating pressure: approximately 6,000 – 15,000 PSI (depending on configuration) - Typical flow range: up to about 2.5 GPM Housing and connections - Housing material: 316/316L stainless steel - Port types available: - Female or male NPT - Compression fittings - 37° flare - Female O-ring ports - Port size range: approximately 1/8" – 9/16" - Mounting: Top mounting holes - Flow direction: Left to right; out-to-in through the element Element media and ratings Available element types include: - Stainless steel wire mesh - Random metal fiber - Porous sintered media Many catalog elements are offered over a broad micron rating range (for example, approximately 0.2 – 200 microns, with some absolute ratings noted in catalog data). Exact options depend on the selected element. Typical applications 4100 Series filters are used in a wide variety of services, including: - Chemical process systems - Compressed gases - Cryogenic fluids (e.g., liquid oxygen, helium, hydrogen) - Ground support equipment - Hydrogen fuel cell systems - Natural gas pipelines - Hydraulic power units - Subsea ROV hydraulic systems If a standard 4100 Series configuration does not fully meet an application requirement, Norman Filter Company frequently customizes filter elements and/or housings to suit specific needs.
