Contamination Exclusion Starts with Desiccant Breathers

Contamination Exclusion Starts with Desiccant Breathers

Desiccant breathers keep contaminants out of oil

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. LE has partnered with Des-Case Corporation, one of the best breather manufacturers in the industry. With this partnership, LE can offer the entire Des-Case® product line as well as provide onsite installation and support. We are one of the largest Des-Case authorized distributors in the U.S.



Desiccant breathers are vital component of lubricant reliability program

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 greater than three microns, and a silica-gel desiccant to remove moisture from the air entering the oil. Des-Case 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.

 

LE offers full line of desiccant breathers and accessories for contamination exclusion in industrial applications



Extended Series Breathers

High-airflow, long-lasting desiccant breathers with check-valve technology ideal for storage tanks, large gearboxes, wind turbines and remote applications

How It Works
Extended Series BreatherAs wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulates, and the color-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.

The desiccant 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. Six high-quality umbrella check-valves are located underneath the unit to isolate equipment from ambient conditions, prolonging breather life and protecting system integrity.

Extended Series Breather Features

  • Six check-valves
  • Integrated nylon standpipe
  • Honeycomb technology oil mist reducer
  • Resilient polycarbonate body
  • Filter element
  • Foam pad
  • Water vapor adsorbent
  • Secondary filter element
  • Threading mount


Standard Disposable Breathers

Standard Disposable Breather

Standard disposable breathers work in a variety of industries and applications. Ideal for intermittent operation in transformers, storage tanks and totes. The breather has an integrated nylon standpipe that can handle high vibration and volatile environments. Each breather is outfitted with a clear polycarbonate casing that allows easy view of color-indicating desiccant in order to monitor when the breather should be replaced. Convenient, simple to install, and can move any lubrication reliability program forward. The filter element captures particles at 3-micron absolute (¦3¡Ý200).

Desiccant Breathers:

  • Eliminate rust-forming condensation
  • Prevent sludge deposits
  • Keep the water out of the oil, providing longer life


Hybrid Breathers

Hybrid Breathers

Ventguard™ Hybrid desiccant breathers are also ideal for low-flow gearboxes and high-humidity applications and outfitted with check valves to ensure no excess pressure or vacuum builds. The internal check valve system creates a nearly sealed system.

Hydroguard™ Hybrid desiccant breathers are ideal for low-flow gearboxes and high-humidity applications. Hydroguard Hybrid 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. The filter element captures particles at 3-micron absolute (¦3¡Ý200). Best suited for continuous operation.

Hydroguard™ and Ventguard™ hybrid desiccant breathers:

  • Eliminate rust-forming condensation
  • Prevent sludge deposits and water-contaminated oil
  • Extend oil and filter life by keeping water and contaminants out
  • Reduce wear and tear on equipment


Extreme Duty Breathers

Hybrid Breathers

Extreme Duty desiccant breathers are designed to take the abuse of vibration, temperature, and challenging environments, making it are ideal solution for mobile equipment, hydraulics, nautical applications, and more. They are outfitted with a rugged housing and an integrated standpipe, allowing for decreased oil misting. The visual indicator windows show the desiccant as it changes color, indicating that the breather should be replaced. These breathers provide three layers of protection to 0.3-micron absolute.

Extreme Duty Breathers:

  • Eliminate rust-forming condensation
  • Prevent sludge deposits and water-contaminated oil
  • Extend oil and filter life by keeping water and contaminants out
  • Reduce wear and tear on equipment


Rebuildable Steel Breathers

Rebuildable Steel Breathers

Rebuildable Steel Desiccant Breathers for high-flow applications feature a rugged carbon or stainless steel 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. Easy-to-replace desiccant bags remove moisture from incoming air, helping extend fluid and equipment life. Replaceable microglass filters prevent particles to 1-micron absolute (¦1¡Ý1000) from entering the system.

Rebuildable Steel Breathers:

  • Eliminate rust-forming condensation
  • Prevent sludge deposits and water-contaminated oil
  • Extend oil and filter life by keeping water and contaminants out
  • Reduce wear and tear on equipment

Rebuildable Steel Breathers can be ordered in a variety of the 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 (microglass / plastisol filter) are available for a customized breather application. Give LE a call if you need something specific regarding an application.
