Rebuildable Steel Breathers

Des-Case Rebuildable Steel (RS) breathers were designed specifically for applications, such as bulk storage tanks or large circulating lube oil systems, where there are very high temperatures, extremely polluted air, or a corrosive environment. They are ruggedly designed, with housings of powder-coated carbon steel or stainless steel. The hygroscopic agent (desiccant) is enclosed in a bag of polypropylene filter material. This desiccant bag filter is easily installed when it is time to replace or recharge the unit. The 1-micron pleated filter has a large surface area, resulting in long service life. Like the bag filter, it is easily replaced without removing the breather from service. Rebuildable Steel breathers accommodate large air flow rates with minimal pressure drops.

Sizing & Applications

Please Note: This is intended as a general guideline for sizing only; other considerations, such as: humidity level, frequency of air flow, ambient temperatures, and chemical compatibility are very important in sizing a breather properly. Larger applications and special circumstances typically require the most thorough analysis. Please contact Ecochem Pumps for assistance in sizing a breather.

– Bulk Storage
– Diesel Tank Storage
– Harsh Environments
– High Flow Applications
– Large Hydraulic Reservoirs

Chemical Compatibility

Please note: Each one is specific to a particular application and customer requests. Please use as a guideline only.

How it works

As air is drawn into equipment through the breather, the pleated filter element removes solid particulate while the desiccant extracts moisture. While in service or during shutdown, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.

The sight glass on the RS unit gives indication to the saturation of the desiccant inside the bags.  When the blue desiccant turns pink, it means it has done its job and is saturated with moisture, keeping it out of your lubricants. It’s time to order the rebuild kits.
