DES-CASE Breathers Range

Desiccant Breathers are a vital step in contamination control. 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 air-flow 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.


  • 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:


DES-CASE Standard Desiccant Breathers

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 defense against humidity for your applications.


DES-CASE VentGuard™ Hybrid Breathers

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

Des-Case VentGuard™ breathers have check-valve technology that isolates the system and only ‘breathes’ when necessary, making them an ideal solution that protect low-flow applications with intermittent operations. Check valves provide slight system pressurization that allows for controlled breathing without excessive pressure build-up. The system breathes only when pressured to do so, and then the air is cleaned and dried before it is introduced into the system, ensuring a clean, dry headspace. This control mechanism also prevents premature saturation of the silica gel and extends breather life, a problem not as easily tackled by standard desiccant breathers exposed to extreme moisture.


DES-CASE HydroGuard® Hybrid Breathers

DC-HG-1 & DC-HG-8

Des-Case HydroGuard® breathers uniquely feature an expansion chamber and internal check valves that create a nearly-sealed system. Designed specifically for steady-state operations with minimal temperature fluctuations, these breathers provide excellent protection in continuous duty applications.


DES-CASE Extreme Duty Breathers


The Des-Case Extreme Duty (XD) desiccant breather has excellent vibration and impact resistance, can withstand broad temperature ranges, has expansive chemical compatibility, and features quality check valve technology while still accommodating higher air flow.  The Extreme Duty breather also has the best filter efficiency of any Des-Case breather―down to 0.3µ absolute (β0.3≥200).


DES-CASE Non-Desiccant Breathers

DC-ND-2 & DC-ND-35

Des-Case Non-Desiccant breathers prevent contamination ingress in low humidity environments or in applications where water-based fluids are in use (e.g. water glycol hydraulic fluid). They help to prevent contamination by preventing free water as well as particles down to 1 micron from getting into the reservoir.


DES-CASE Flange Adapter


Connects Standard Disposable (DC-2, DC-3, DC-4), VentGuard (DC-VG-2, DC-VG-3), HydroGuard (DC-HG-8) breathers to 1" female NPT adapter
