BREATHERS BREATHERS
Rebuildable Steel Breathers
Rebuildable Steel (RS) breathers were designed specifically for applications such as bulk storage tanks
or large circulating lube oil systems with very high temperatures, extremely polluted air, or a corrosive
environment. They are ruggedly designed with housings of powder-coated carbon steel or stainless
steel. Rebuildable steel breathers accommodate large air flow rates with minimal pressure drops.
Rebuild kits including a 1-micron pleated replacement filter element, desiccant bag filter, sight glass
indicator, foam pad, and gasket which are easily replaced without removing the breather from service.
APPLICATIONS: OPERATING ENVIRONMENTS: REBUILDABLE STEEL BREATHER KITS (DC-RS-X-RK):
• Bulk Storage • Harsh Environments Note: Substitute the appropriate RS model number for the “X” in the rebuild kit part number. (Ex. DC-RS-3-RK)
• Diesel Tank Storage • Harsh Chemicals • Rebuild kits are available in a variety of materials to meet chemical compatibility needs.
• High Flow Applications • High Temperature • Desiccant bags above an RS-25 are packaged in 25 lb increments for easy handling.
• Large Hydraulic Reservoirs • Des-Case recommends use of a pressure/relief valve on any tank or storage system.
• Chemical Tanks
