WHY A BREATHER IS IMPORTANT

Whitmore manufactures Air Sentry desiccant breathers from materials defined as solid waste by most state and federal environmental regulations.

Once in service a breather can adsorb lubricants or fluids (splashing, vapors or mist) from the reservoir it protects. If this occurs, the breather should be disposed of according to local environmental laws regarding the lubricant or fluid.

ALWAYS CHECK LOCAL REGULATIONS REGARDING WASTE DISPOSAL.

APPLICATIONS

Air Sentry Breathers should be an integral part of any proactive maintenance and reliability program.

Applications fall into 3 primary categories:

  • Gearboxes
  • Hydraulic Reservoirs
  • Storage Tanks (drums and totes)
applications

BENEFITS

The lifespan of equipment corresponds directly to the cleanliness level and “dryness” of the lubricating oil.

Desiccant breather cost-saving benefits:

  • Extends the service life of lubricants and oil filters
  • Eliminates condensation / rust formation
  • Improve equipment and plant efficiency
  • Desiccant breathers are simplest and most cost-effective contamination control protection available.
  • Silica gel desiccant removes up to 95% of moisture from incoming air
benefits

AIR SENTRY VS. COMPETITION

  • Air Sentry breathers have more silica gel. There is no center stand pipe to waste valuable desiccant space.
  • Air Sentry has a larger particle filter. Air vents around the top cap allows more surface area to trap particles.
  • Air Sentry color change is easy to monitor. The clear tube is visible from 360°.
  • Air Sentry offers the longest lasting desiccant breather in the market, Guardian.
  • Air Sentry is the BEST value. Best value as in terms of product and equipment life, performance and maintenance costs.

HOW AIR SENTRYBREATHERS WORK

  • A reservoir vent allows air pressure within a reservoir to equalize with the ambient environment.
  • Variations in air pressure created by thermal expansion and contraction, fluid level changes created by pumps, motors or the filling and emptying process drives the airflow.
  • This ebb and flow of air pressure exposes lubricants to the two most damaging contaminants – water and dust particles.
  • Lubricants are naturally hydroscopic drawing moisture from humid air.
  • Condensation forms on the inside surfaces as equipment cools.
  • Desiccant breathers ensure CLEAN, DRY AIR!
  • A desiccant breather (cartridge) should be replaced when the silica gel is totally green. Doing so allows the user to get full value from the breather.

When silica gel turns green, air can still flow thought the breather, the particle filter traps dust; the process of blocking airborne moisture comes to an end.

BREATHER SOLUTIONS

Air Sentry offers eight different series with multiple models.

For most applications, there are three possible solutions:

  • GOOD: Completely disposable, providing the lowest initial cost of installation.
  • BETTER: Check valve design provides a longer service life than deposable models.
  • BEST: The best value, lowest total cost of operation, extended service life.
