Abstract
Lubricant in exhaust fluid from a pneumatic motor is extracted by a separator. The separator comprises a housing in which a cyclonic flow of the exhaust is created to expel the lubricant in the exhaust. The exhaust is directed through a turbine within the housing wherein lubricant is deposited on blades of the turbine and then expelled against a housing wall by rotation of the turbine. After passing through the turbine blades, the exhaust flow is forced to reverse direction thereby extracting additional lubricant due to centrifugal force. After the lubricant has been extracted, the exhaust flows through a filter to remove other particles before exiting the separator.
