Air Line, Coalescing Filter, Parker 12F21EC

Description 12F= Coalescing Filter Standard 2= 3/8″ Port 1= Twist Drain E = Grade 6 C= Current The contaminated air enters the element interior and is forced through a thick membrane of borosilicate glass fibers coated with epoxy (A). Flow then passes through an outer structural support and, at this stage, has removed up to 99.97% of the sub-micron particles evident in the contaminated air. These tiny droplets coalesce together and are blotted from the filter surface by the drain and release layers of non-woven glass felt and rayon cloth. The drops now begin a gravitational passage to the filter sump (B) where they can be manually or automatically drained. The clean, filtered air now passes through the outer screen plastic net and out into the pneumatic system. The Air Line Coalescing Filter removes liquid aerosols and sub-micron particulate matter. Collected liquids and particles in the “quiet zone” should be drained before their level reaches a height where they would be reentrained in the flowing air. This can be accomplished by the manual drain (C) which is actuated by twisting knob (D) counterclockwise. On the 30 Series, unscrew the drain valve (E) slightly until the liquid begins to drain. Features • Removes liquid aerosols and sub-micron particles. • Liquids gravitate to the bottom of the element and will not re-enter the airstream. • Oil free air for critical applications, such as air gauging and pneumatic instrumentation and controls. • Interchangeable twist and automatic float drains. • Pressure differential indicator standard. • Shown with recommended metal bowl guard. • High Flow: Grade 6 Element 3/8″ – 73 SCFM § 1/2″ – 75 SCFM § 3/4″ – 80 SCFM §
