Collecting and recycling oil vapours

Demister protects humans, machines and the environment

When hydraulic systems are subjected to extreme temperature fluctuations and expansion caused by heat, oil vapours form, which can escape from the tank or gear unit via tank filler breathers and desiccant breathers. It was never easier to collect and recycle these hazardous vapours: With the new oil demisters from the TBA-OD series by Stauff. These are installed between the top side of the tank and the breather and make use of the higher inertia of the oil vapours compared to the escaping air during pressure differences. The fluid particles collide with the aluminium ridge integrated in the housing and form droplets which accumulate and flow back into the hydraulic tank.

Particularly in the case of dynamic operating conditions with extreme fluid level fluctuations, they also create an increase in the distance between the breather and the tank and ensure a long lifespan of the system components. Staff, equipment and the environment are effectively protected against escaping oil.

In contrast to the previous method, in which a specific quantity of active carbon material was added to the drying agent of the desiccant breather, the new oil demisters of Stauff’s TBA-OD series are based solely on a mechanical functioning principle, are completely maintenance-free and don't need to be inspected, cleaned or replaced after a specified number of operating hours. 

They are available in two lengths of 140 mm and 210 mm, suitable for airflows up to 1 m³/min and can be installed on the hydraulic tank by means of two BSP connection threads or a corresponding adaptor plate. Subsequent integration into existing configurations is also easily feasible.

Background Information

Walter Stauffenberg GmbH & Co. KG was founded in the 1950s in Werdohl, in the German province of North Rhine-Westphalia, and was initially a contract turning shop. Today the company operates under the trade name STAUFF, developing, producing and marketing fluid technology components for use in plant construction and mechanical engineering. In the fields of tube, pipe and hose clamps, measuring technology and hydraulic filtration, STAUFF is one of the world’s leading organisations in a growing industrial segment. 

Meanwhile, more than 1100 employees (12/2013) in 18 companies generate an annual turnover of more than EUR 190 million (12/2013) worldwide. Additional distribution subsidiaries have recently been opened in Ireland, Malaysia and Vietnam. Besides the group headquarters in Werdohl Ehrenfeld, the company has production and logistics facilities in the German cities of Plettenberg-Ohle and Neuenrade-Küntrop.
