R-Series - High Vibration

r-series featuresair sentry brochure

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! R-Series breathers are also available with activated carbon or a combination of carbon and silica via special order - please call for more information.
