Lubricant contamination is one of the leading causes for machine failure, and contamination can begin before the lubricant ever enters the machine. Gearboxes, pumps and reservoirs have to “breathe” when the air expands and contracts, as well as when incoming fluid displaces air, or when air is drawn in when hydraulic components activate. Each time a unit breathes in, it brings with it all sorts of small debris and moisture, depending on the operating environment. Over time, the effects of this contamination can be damaging to the lubricant and to the equipment.
Water-contaminated oil can lead to additive stripping, and eventually the water can cause corrosion and rust. Small particulates no larger than three microns (the diameter of a single human hair is 40 microns) can cause unwanted machine abrasion. All of these problems accelerate wear and lead to costly repairs. The simple solution to these problems is the use of desiccant breathers, which can stop water and particulates from contaminating the lubricant in the first place. From the time oil enters your facility to the end of its useful life, protecting it with desiccant breathers will extend the life of the oil and the equipment, decrease downtime, and save you hundreds of thousands of dollars.
Studies have shown that 50-70% of lubricant contamination comes from outside the equipment. Most machines are designed to “breathe,” so protecting the source of airflow from moisture and particulate contamination is extremely important. This is true for most sizes and types of machines.
Breathers are sized according to the required cubic feet per minute (cfm) of air exchange for each machine application. The desiccant beads in the breathers change color as they become saturated with moisture, indicating that the unit is spent. Desiccant breathers use filter media to remove particles and a silica-gel desiccant to remove moisture from the air entering the oil. Xclude desiccant breathers incorporate a high capture-efficiency filter to help sustain desired cleanliness levels by removing even minute particulates.
They also create low relative humidity levels in the headspace, making condensation and absorption by the lubricant unlikely. When a system is properly fitted with a breather that contains drying and filtration media, contaminant ingression is greatly reduced. Installation of desiccant breathers at critical ingression points is a cost-effective means to prevent contaminants from entering the fluid reservoirs as differential pressures occur.
Xclude™ Desiccant Breathers
Providing basic protection from moisture and particulate contamination in lubricants and equipment, Xclude™ Standard Breathers replace the standard dust cap or OEM breather cap on equipment. They work great in totes, transformers, storage tanks and hydraulics in a variety of industries. They are convenient and simple to install. Their clear casing allows easy viewing of color-indicating desiccant in order to monitor when the breather should be replaced. They can withstand high vibration and volatile environments.
As air is drawn into equipment through the breather, the layered filter elements remove particulates while the desiccant beads strip harmful moisture. While in service or during shutdown, the desiccant attracts moisture from inside the equipment reservoir, actively drying the equipment.

Xclude™ Extended Series Breathers are high-airflow, long-lasting desiccant breathers with check-valve technology. They are ideal for storage tanks, large gearboxes, wind turbines and remote applications.
As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulates, and the 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. The breather is outfitted with a resilient nylon standpipe and polypropylene oil mist reducer to allow oil mist to coalesce and drain back into the reservoir, rather than compromising the desiccant. Check-valves are located underneath the unit to isolate equipment from ambient conditions, prolonging breather life and protecting system integrity.

Xclude™ High Humidity Expansion Chamber Breathers are best suited for low-flow gearboxes and high-humidity applications with continuous operation. These high humidity desiccant breathers feature an expansion chamber to isolate lubricants from all levels of ambient humidity, keeping out harmful particles and creating a nearly sealed system to protect the equipment.
Xclude™ High Humidity Check Valve Breathers are best suited for low-flow gearboxes and high-humidity applications with intermittent operation. They are outfitted with check valves to ensure no excess pressure or vacuum builds. The internal check valve system creates a nearly sealed system.

LE’s most versatile breather solution, Xclude™ Extreme Duty Breathers are designed to take the abuse of vibration and impact, broad temperature range, chemicals and other challenging environments, making them an ideal solution for application such as mobile and off-road equipment, hydraulics and nautical applications. The rugged housing and integrated standpipe allow for decreased oil misting. Quality check valves isolate the system while accommodating airflow. The visual indicator windows show the desiccant as it changes color, indicating that the breather should be replaced.
As wet, contaminated air is drawn through the unit, multiple filter elements remove solid particulates while the 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.

Xclude™ Rebuildable Steel Breathers for high-flow applications feature a rugged housing to protect equipment from moisture and contaminants, even in the toughest environments. Rebuildable steel breathers are perfect for hydraulic reservoirs, bulk oil storage, diesel tank storage, and where chemical or harsh environments exist.
Xclude Rebuildable Steel Breather Highlights
Rebuildable Steel Breathers can be ordered in a variety of different materials to meet chemical compatibility needs. A variety of steel housings (304 stainless & 316 stainless steel), gasket /seal material (Viton, SBR and EPDM rubber), desiccant media (activated carbon, molecular sieve, activated alumina), and filter materials (micro-glass / plastisol filter) are available for a customized breather application. Give LE a call for assistance with particular applications.
Xclude™ Non-Desiccant (ND-2) Breathers prevent contamination when humidity is not an issue. They can be used for applications such as oil sight glasses and small gearboxes. As wet, contaminated air is drawn through the unit, the hydrophobic media repels water while the particulate filter captures dirt, preventing both from entering the equipment.
Xclude Non-Desiccant (ND-2) Breather Highlights
Xclude™ Non-Desiccant (ND-35) Breathers prevent contamination when humidity is not an issue. Intended applications include low-humidity applications, water-based lubricants, high-dust environments and oil-misting applications. As wet, contaminated air is drawn through the unit, the hydrophobic media repels water while the pleated particulate filter provides a large surface area and protects against particulate contamination. The unit also blocks free water from the reservoir.
