Series 21 Mini In-line filters are economical filters for test stands, meters, gauge protection, relief valves, pneumatics, hydraulics and much more. Maximized surface area and strength made possible by precision pleated stainless steel wire mesh discs. Wire mesh and sintered metal media options with particulate removal efficiencies from 0.2 to 300 micron.
We have an extensive cross reference for Norman Filters and 3B Filters.
