while the coalescing filter removes oil mists, aerosols, and minute particles.
Finally , the adsorbing filter effectiv ely eliminates odors from Freons , alcohols,
esters, ketones, and up to 99% of most hydrocarbons.
FEATURES:
• General purpose lter with 5-micron rated polyethylene lter element
• Coalescing lter with 0.3-micron rated coalescing element; optional
0.01-micron element
• Adsorbing lter with activated carbon element
• Modular or inline mounting
• Polycarbonate plastic bowls with steel shatterguards; optional metal bowls
• Gold cap color; optional gray, yellow, red or blue
• Optional extended metal bowls for coalescing and adsorbing lters with
higher flow filter element
• Internal automatic drains for general purpose and coalescing lters;
internal float drain; manual drain for adsorbing filter
