Special Features:

Air pressure must be limited to 120 psi for supply and 50 psi for instrument signal to avoid damage to the positioner; supply air must be clean, dry and oil free instrument quality air in accordance with isa s7-3 specification (dew point >18 degrees below ambient temperature, particle size <5 microns, oil content <1ppm); nha: positioner valve, electro-pneumatic, a51146 aft

Properties:

A replaceable device designed to remove solid particles from fluids ranging in density from heavy liquids to gases. The removal of particles is accomplished by porous material (metallic or non-metallic), stacked disks, wound wire, or the like, constructed so the fluid can flow through the device while the solid particles are retained. It may be designed to fit into a filter, fluid (or similar cavity), or it may have an integral outer casing and mounting facilities and be designed to connect directly to an engine, compressor, or the like. The degree of removal of particles must be nominally rated at less than 50 microns or absolutely rated at less than 75 microns. Excludes filter element, air conditioning. See also strainer element, sediment.
