M-Series breathers are designed from heavy duty materials capable of handling the requirements of the most severe environments. They replace the standard breather cap or vent tube on tanks and reservoirs. Pipe threads on the bottom standpipe make the units easy to install.

All M-Series designs have 2 micron pleated filters and silica gel bags that are easily replaced. The M-Series design features our proprietary Splash Sentry®. This device is included in all M-Series models and prevents foaming or splashing fluids from entering the breather during normal operating conditions.

R-Series breathers are suitable for high vibration applications including off-road vehicles, construction vehicles, haul trucks, and farm vehicles typically equipped with hydraulic fluid reservoirs.

R-Series breathers are easily mounted in place of standard breather caps via rugged steel pipe threads, included with all models except the R-111. The R-Series rebuildable design allows for economical replacement of the desiccant cartridge.

Filter Technologies is an authorized distributor for Air Sentry® Dessicant Breathers. Dessicant breathers are used for contamination control in major industrial, mining, military, power generation, and fluid storage applications.

Air Sentry® Breathers remove water, solid particles, and other contaminants from air being breathed into reservoirs, transformers, storage tanks, and gearboxes. The service life of equipment and fluids is greatly extended when protected by an Air Sentry® Breather.

Air Sentry® Breathers should be an integral part of any proactive maintenance and reliability program. Designed to replace the breather cap or air filter on gear boxes, hydraulic fluid reservoirs, bulk storage tanks, oil drums, oil-filled transformers, and other fluid reservoirs, Air Sentry® breathers adsorb water from the air before it enters your fluid system and remove particulate contaminants as small as 2 microns.

You will know when the dessicant needs replacement, the silica gel changes color when it is fully depleted, turning from a gold color to dark green. This makes it simple to identify the condition of a breather and quickly replace the breather, maintaining the cleanliness of the fluid reservoir.

Air Sentry® Z-Series breathers are designed for applications where space is limited or air flow requirements are below 10 cubic feet per minute (cfm).

The Z-Series breather is typically used on gearbox applications and has been proven to work well on low fluid volume applications where mounting space is limited or where a larger breather won’t fit without remote mounting.

XR-Series breathers are designed for extreme environment applications where protection from dust, moisture and vibration are critical. 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 implements two check valves to prevent outside moisture and solid contaminants from entering the breather until there is a need for airflow. The XR-Series design allows for economical replacement of the desiccant cartridge.

X-Series breathers are the perfect solution for high humidity and high dust environments. To extend the desiccant’s life in these environments, the X-Series incorporates two check valves.

The intake check valve allows airflow into the breather only when differential pressure between the atmosphere and reservoir exceeds a 0.3 psi threshold, while the exhaust check valve permits air to exit the reservoir when the differential pressure between the reservoir and atmosphere exceeds a 2.1 psi threshold, providing a closed system until air flow is required. The check valves extend the life of the desiccant by allowing the air to flow through the breather only when needed to protect the integrity of the tank.. The X-Series rebuildable design allow for economical replacement of the desiccant cartridge.

L-Series 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 enters the filter/dryer in one end and is cleaned and dried before leaving the other end. Solid particles are removed down to 2 microns. Activated carbon versions are ideal for removing undesirable fumes and odors from air or other gases being vented to the atmosphere.

Application Brief:

Filter Technologies provided a dessicant breather to a beverage plant maintenance dept. The maintenance crew was changing the lube oil on 20 hp pump every few weeks. After a few days in service the oil would become visibly contaminated with water. Humidity and washdowns were making its way into the reservoir. After an Air Sentry X-Series Breather was installed, the oil still remained like new after 8-weeks in service. The color went from Gold to Green over this span, enabling longer service life for the lube and machinery. Downtime is avoided, which if a production line goes down, means significant amounts of lost revenue for the company. Four more breathers were purchased to protect the company's production processes.

What does unnecessary downtime cost your company? Are your lube reservoirs protected?
