Breathers Air dryers
Breather - dryers are clever tools that absorb moisture and dirt from the air before it enters in the lubricant. They consist of a particle filter ( efficiency 0.5 - 2 µ ) and a special drying chemical with integrated saturation indicator ( desiccating breather, dessicant, drying beads, drying gel, silicagel ) . Lubretec provides two brands : Air Sentry and Lubesec .
The technology is simple : breather air for lubricant tank or hydraulic reservoir is being filtered trough the particle filter and consecutively passed trough the drying gel part ( desiccant ) of the breather. In this way only pure clean and dry air enters the reservoirs or tanks and cannot contaminate the lubricants or other fluids.
Total Protection factor !
When the saturation indicator of the desiccant changes its color ( with Lubesec, Air Sentry en Guardian allaways from dark yellow to green ) it is time to change the breather, cartridge or drying chemical.
