Standard Breathers:
Typical Industries
• Power Generation
• Mining
• Aviation
• Storage
• Manufacturing
• Petrochemical
By the Numbers: 
1–Integrated Nylon Standpipe
The integrated standpipe provides excellent vibration re
sistance and dissipates impact throughout the unit, elimi
nating weak points. It also allows even airflow distribution 
throughout the unit, eliminating inaccurate readings of 
desiccant saturation.
2–Resilient Polycarbonate Body
Shock-absorbing, clear casing provides reliable service and 
easy maintenance.
3–Filter Element
Polyester filter element removes airborne contamination to 
3-micron absolute. Unique loops allow particles to release 
during system exhalation, helping to increase breather life.
4–Foam Pad
Foam filter captures any oil mist and disperses incoming 
air evenly over filtration and drying areas.
5–Water Vapor Adsorbent
Silica gel adsorbs water from incoming air and can hold up 
to 40% of its weight. Condition is indicated by change of 
color from blue to light pink.
6– Secondary Filter Element
Second polyester filter element protects against migration 
of desiccant dust, providing maximum efficiency. 
7–Threaded Mounting
Easily replaces standard filler/breather cap with multi-fit 
connection or one of several adapters.
8–Air Vents
Individual air intakes are opened based on flow require
ments of the system. Plugs protect unit during shipping 
and storage.
