Breather
Air Sentry® Contamination Control Breathers replace existing breather caps or air vents on fluid holding tanks, reservoirs and gearboxes. Most older style air venting methods provide minimal if any contamination control. Air Sentry® breathers provide the first line of defense in contamination control methodology utilizing patented designs and featuring color indicating silica gel and self cleaning 2-micron filtration.
Air Sentry desiccant breather are ideal in many industries including industrial, production, power generation, and many others because of their flexibility for use on tanks, reservoirs, transformers, pumps, and motors. Replace current breather caps to provide clean, contamination free air into your system.

D-Series-Disposable and Stationary
Air Sentry D-Series breathers feature numerous models in a variety of sizes, designed to satisfy the requirements of most stationary fluid management applications.
- Storage Tanks
- Fluid Reservoirs
- Transformers
- Pumps
- Gearboxes
The Air Sentry D-Series breathers feature numerous models in a variety of sizes, designed to satisfy the requirements of most stationary fluid management applications. The breathers provide application flexibility by using 100% silica gel for moisture adsorption or 100% activated carbon for fume and odor control, or both when necessary. (Carbon filters are special order – please call for more information) All D-Series models feature 2-micron solid particle filtration and are available with airflow ratings of 20 cfm.
The D-Series is constructed of industrial grade raw materials, tested to ensure a wide range of chemical compatibilities, and features high impact resistant ABS top and bottom caps. The clear acrylic tube makes it easy to inspect the condition of the color-changing silica gel from a distance. The silica gel turns from gold to dark green to visually indicate the adsorption of moisture and confirm the breather is getting the job done!
L-Series-In-line Low Airflow
In-Line Low Airflow Applications.
Air Sentry® In-Line Filter / Dryers remove water vapor and solid contaminants from air exhaust lines, low pressure compressed air lines, vacuum lines, and other in-line airflow applications where clean, dry air is required.
- Air Exhaust Lines
- Vacuum Lines
- Low Pressure Compressed Air Lines
- Marine Vehicles
Air Sentry® In-Line Filter / Dryers remove water vapor and solid contaminants from air exhaust lines, low pressure compressed air lines, vacuum lines, and other in-line airflow applications where clean, dry air is required.
The L-Series breathers are available with 100% silica gel or activated carbon, or a combination of both, as necessary. (Carbon filters are special order – please call for more information)
Air enters the filter / dryer in one end and is clean and dry when leaving the other end. Water vapor and solid particles down to 2 micron are removed. The L-Series is rated up to 60 psi and mounted on the regulated side of the air line. This series offers these benefits:
-Minimize rust and corrosion
-Reduce component wear
-Reduce maintenance costs
-Prolong fluid life
-Reduce oil oxidation
-Eliminate fumes and odors
M-Series-Heavy Duty
Air Sentry M-Series breathers are designed from heavy-duty materials capable of handling the requirements of the most severe environments.
- Heavy Duty Off-Road Equipment
- Mobile Heavy Equipment
- High Temperatures
- Corrosive Chemicals
All M-Series designs have 2 micron pleated filters and silica gel bags that are easily replaced. They also feature the proprietary Splash Sentry™, which prevents foaming or splashing fluids from entering the breather during normal operating conditions. M-Series breathers are also available with activated carbon or a combination of carbon and silica via special order – please call for more information.
R-Series-High Vibration
Air Sentry R-Series breathers are ideal for these high vibration, mobile applications, including off-road, construction and farm vehicles.
- Cranes
- Railroad Maintenance of Way Equipment
- Farm Implements
- Construction Vehicles
- Off-Road Trucks
Most heavy equipment – productive and on the move – is outfitted with hydraulic fluid tanks or reservoirs which breathe in the dirty outside air.
Air Sentry R-Series breathers are ideal for these high vibration, mobile applications, including off-road, construction and farm vehicles. R-Series desiccant breathers are easily mounted in place of standard breather caps via rugged steel pipe threads and a reusable metal base.
When the gold silica gel cartridge turns dark green, simply install a new replacement cartridge to keep things moving!
X-Series-High Humidity/Dust
Air Sentry X-Series Breathers are the perfect solution for high humidity and high dust environments.
- Paper Mills
- Wash-Down Areas
- Steam Cleaning Rooms
- Mine Quarries
To extend the desiccant’s life, the X-Series incorporates 2 check valves and a reusable top cap. The check valves provide a closed system until airflow is required, extending the service life of the desiccant. Specifically, the intake check valve allows airflow into the breather only when differential pressure between the atmosphere and fluid reservoir exceeds a 0.1 psi threshold, while the exhaust check valve permits air to exit the reservoir when the differential pressure exceeds a 2.0 psi threshold. A 0.1 psi check valve is also available for exhaust.
When the gold silica gel has turned dark green, remove the reusable top cap from the bottom desiccant cartridge, dispose of the spent dark green desiccant cartridge, then use the same top cap with a replacement cartridge.
XR-Series-Extreme Environment
Air Sentry XR-Series breathers, originally conceived for the wind power industry, are designed to perform in any extreme environment where protection from dust, moisture and vibration are critical.
- Windmills and Wind Power Generation
- Mining Equipment
- Mobile Equipment
XR-Series breathers include a metal reinforced base available with male NPT threads to adapt to your equipment. The base is designed to handle the rigors of high vibration applications. The top cap uses two check valves to prevent outside moisture and solid contaminants from entering the breather until there is a need for airflow. The rebuildable design allows for economical replacement of the desiccant cartridge.
Z-Series-Limited Space
Air Sentry Z-Series is designed for applications where space is limited or air flow requirements are below 5 cfm.
- Gearboxes
- Drums
- Totes
- Small Oil Containers
- Oil Safe brand Oil Storage Systems
The Z-Series is typically used on gearboxes and low fluid volume applications where mounting space is limited or where a larger breather won’t fit without remote mounting.
