Breathe Easy

D-Series Breathers are designed to satisfy the requirements of most stationary applications involving hydraulic reservoirs, lubricant and fuel storage tanks, transformers, pumps and gearboxes. D-Series models provide application flexibility by using 100% silica gel for moisture adsorption or 100% activated carbon for fume or odor control, or a mixture of both when necessary. All D-Series models feature 2-micron solid particle filtration and are available with airflow ratings of 35 cfm to 250 cfm. The D-Series is constructed of industrial grade raw materials and feature high impact resistant AB top and bottom caps. The clear acrylic window makes it easy to inspect the condition of the color changing silica gel from a distance. The silica gel turns color from gold to green to visually indicate the adsorption of moisture and confirm the breather is doing its job!

Most mobile equipment, including maintenance of way equipment, farm implements, and off-road vehicles, are equipped with hydraulic fluid tanks or reservoirs which breathe outside air. 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 UC-R111. The metal reinforced base is reusable. When the silica gel cartridge turns color from gold to dark green, simply install a new replacement cartridge to the reusable metal base!

Our Z-Series Contamination Control 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 use 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.

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 breather 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 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. In addition to having a rugged design, X-Series breathers include a top cap that can be reused when the desiccant is spent. When the color of the silica gel has turned dark green, remove the reusable top cap from the bottom desioccant cartridge, dispose of the spent dark green desiccant cartridge, then use the same top cap with a replacement cartridge. The X-Series rebuildable design allow for economical replacement of the desiccant cartridge.

The M-Series breathers are designed from rugged, heavy duty materials that are capable of handling the requirements of the most severe environments. Pipe threads on the bottom standpipe make the units easy to install. The design also includes a proprietary splash guard that is included on all models and prevents foaming or splashing fluids from entering the breather during normal operating conditions. All M-Series breathers have a 2 micron pleated filter and silica gel bags that are economical and easy to replace.
