Walker Filtration has developed a range of 5 Odasorb vacuum pump exhaust filters with flow rates from 50 to 250 Nm³/h (30 to 150 scfm). For rotary vane type vacuum pumps with internal oil separation, oil odours are often a problem especially in confined areas. The Odasorb is designed to effectively remove oil mist and unpleasant odours.

Odasorb filters are self-contained units with no requirement for external housing, making them completely disposable and easy to replace.

This filter element with internal threaded connection and high-performance activated carbon filter media can be fitted directly to the pump outlet to provide a safe working environment. Odasorb can also be connected to a Walker Filtration vacuum exhaust filter to provide additional odour removal. The filter also assists in exhaust noise reduction.
