Des-Case Standard Series Desiccant Breathers

Des-Case Standard Breathers


Des-Case Standard Desiccant Breathers are a vital step in oil contamination control and the first line of defence against lubricant contamination. Studies have shown 50-70% of lubricant contamination can come from outside the equipment.


As most machines are designed to 'breathe', protecting the source of airflow from moisture and particulate contamination is vital. Des-Case Breathers attack the source of contamination, making the products an affordable and cost-effective solution to extend lubricant life and to increase equipment productivity.


Key Benefits:

  • Removes moisture in the headspace of equipment
  • Eliminates rust-forming condensation
  • Prevents sludge deposits and water-contaminated oil
  • Prevents contamination ingress
  • Provides longer lubricant life
  • Reduces wear and tear on equipment, prolongs life


Neilson Hydraulics supplies the following DES-CASE Breathers from the Standard Desiccant Breather range:


DC-BB, DC-1, DC-2, DC-3 & DC-4

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 defence against humidity for your applications.

 Inside A Des-Case Desiccant Breather:

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.



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
