Features:

Removes liquid aerosols and sub-micron particles
Protects pneumatic systems from contamination that standard
particulate filters will not catch.
Two different grade elements are available
Differential pressure pop-up indicator standard
High flow design

Note: All coalescing filters should be protected by a
particulate filter (i.e. F602) installed upstream.

Element Grade Application
6
General air coalescing applications when total removal of liquid aerosols and suspended fines is required in all pressure ranges. Protection of air dryers, air gauging, air logic, modulating systems, critical air conveying, most breathing air systems, etc.
7
Pre-coalescer or pre-filter for Grade 6 to remove gross amounts of water and oil, or tenacious aerosols which are difficult to remove. Upgrading existing particulate equipment to coalescing without increase in pressure drop.
