Actively combating oil vapours

Press release on the occasion of Maintenance Dortmund

When air can flow through a tank filler breather of a hydraulic reservoir, it can be the source of moisture penetrating into the system. Temperature fluctuations cause the water in the air to condense, which negatively impacts the aging process of the hydraulic fluid, eventually leads to serious damage of system components and can be the reason for expensive machine downtimes.

With Stauff desiccant breathers of the SDB series, the air flowing in first passes through a drying agent made of non-toxic gel and subsequently through a replaceable air filter element with a micron rating of 3 µm.

The colour of the drying agent gradually changes from red to orange with increasing moisture absorption. This allows the condition of the desiccant breather to be determined easily and quickly. Like the air filter element, which can be monitored with an optional visual clogging indicator, the drying agent can also be replaced as required, without any great installation expense.

Any hazardous oil vapours that can be released in the air coming from the hydraulic reservoir are bound by the additional use of activated carbon material in the desiccant breather. To do so, one third of the regular gel beads are removed and replaced by a layer of activated carbon. Due to the highly absorbent inner surfaces and extremely hydrophobic characteristics, activated carbon is optimal for removing oil vapours and odours from exhaust.

SDB desiccant breathers are attached to the container with a threaded connector or an adapter plate. They are suitable for maximum air flow rates up to 1.50 m³/min.
