Providing Quality Oil Care to Industry

Des-Case Standard Series Desiccant Breathers

Des-Case Standard breathers provide simple, yet dependable protection from moisture and particulate contamination in lubricants and equipment across multiple industries and applications. These versatile breathers are five times more effective than the leading non-desiccant breathers, providing optimal defense against humidity for your applications.

EXPLORE

As wet contaminated air is drawn through the desiccant breather unit, multiple 3-micron polyester filter elements remove solid particulate and the colour-indicating silica gel extracts moisture. When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere.

Standard Breather Cut Thru

1 Domed Cap

A domed cap allows for better washdown runoff

2 Integrated Nylon Standpipe

The integrated standpipe provides excellent vibration resistance and dissipates impact throughout the unit, eliminating weak points. It also allows even airflow distribution throughout the unit, eliminating inaccurate readings of desiccant saturation.

3 External Ribs

External ribs on shell to create greater durability and grip when installing or replacing breather

4 Integrated Drip Ring

An integrated drip ring keeps shedding water from entering the vent holes

5 Threaded Mounting

Easily replaces standard filler/breather cap with multi-fit connection or one of several adapters.

6 Air Vents

Individual air intakes are opened based on flow requirements of the system. Plugs protect unit during shipping and storage.

7 Foam Pad

Foam filter captures any oil mist and disperses incoming air evenly over filtration and drying areas.

8 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.

9 Enhanced Seal

An enhanced seal eliminates potential for airflow bypass


HOW IT WORKS

This breather unit replaces the standard dust cap or OEM breather cap on equipment. As air is drawn into equipment through the breather, the layered filter elements remove particulate while the desiccant beads strip harmful moisture.

While in service or during shut-down, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.

Please Note: This is intended as a general guideline for sizing only; other considerations, such as: humidity level, frequency of air flow, ambient temperatures, and chemical compatibility are very important in sizing a breather properly. Larger applications and special circumstances typically require the most thorough analysis. Please contact Des-Case for assistance in sizing a breather.
