描述
The PSS® Series filter medium is composed of 316 lowcarbon stainless steel powder sintered together in an inert environment. The resulting fixed pore structure medium provides quantitative particle removal efficiency without media migration or particle unloading. The inherently high void volume of this medium offers low resistance to flow and high dirt holding capacity. These filters offer broad temperature and chemical compatibility with the added economy of being repeatedly cleanable. PSS filters are used in many applications within the chemical process industry, in many aggressive environments, where critical filtration levels are required. Such applications include industrial gases (cryogenic and high temperature), steam, solvent, heat transfer fluids, polymers, chemical intermediates, food and beverages. PSS Series filter media have high chemical stability and do not impart taste, odor or extractables to the effluent. Designs are available for temperatures up to 1250°F with appropriate alloy selection.
Specifications
Sizes
Standard PSS filters are available in three styles. Industrial (1000 style) cartridges are 2 3⁄8-inch diameter double openended modules in incremental lengths of 10 inches; sanitary design (AB style) are closed on one end with an O-ring piston seal on the other end; and cylindrical elements, which are 1 1⁄2-inches or 2 3⁄8-inches in diameter, closed on one end with a threaded fitting connection on the other.
Performance
Operating Characteristics
Standard 316 stainless steel cartridges are capable of withstanding a minimum collapse differential pressure of 50 psid in the forward flow (outside-in) direction to 600°F* and 50 psid in the reverse flow direction. Threaded connector series only. Due to seal limitations,
*Threaded connector series only. Due to seal limitations, 1000 Series suitable for applications up to 450°F.

* These removal ratings should be used when comparing PSS to competitive grades.
1Liquid removal efficiency ratings are based on a modified F2 test method and actual particle count data.
2Weight percent removal data based on AC Fine Test Dust in air. Absolute retention ratings based on actual particle count. 3Pressure drop in psi obtained by multiplying value shown by actual flow desired in gpm, viscosity of liquid in centipoise (if other than 1 cp), all divided by total filtration area (ft 2) selected. See Table 2 for area.
4Pressure drop in psi obtained by multiplying value shown by actual gaseous flow rate desired (acfm), ratio of viscosities
