Desiccant Air Breathers
SDB/SVDB Series

Stauff_Filter_Desiccant_SDB_SVDB

Specifications

  • Combination air breather and water removal filter to handle flows up to 1500 l/min (395 US GPM)

Available in two types

  • SDB Series has a 3 micron absolute air filter. When saturated either the air filter or desiccant gel can be replaced as needed.
  • SVDB Series has a 10 micron nominal filter. When saturated, the entire unit is replaced.
  • Adaptor plates and fittings available for easy installation
  • Z-R Desiccant gel is non toxic according to EC Council directive 88/379/EEC
  • Available with active carbon for vapor filtration

When a reservoir or gearbox breathes, air containing water vapor is ingested into the system. Temperature fluctuations will cause this water vapor to condense. This condensed water will speed up the oxidation of the fluid and lead to damage in the system. The Stauff desiccant Air Breather first dries the air as it passed through the Z-R gel and then the dry air passes through a 3 micron synthetic media element (SDB Series) to remove any solid contamination particles. As moisture is absorbed the gel will gradually change from red to orange. When the gel is orange, either replace the gel (SDB Series), or replace the entire unit (SVDB Series). An optional "filter minder" gives an indication of the status of the air breather.
