ABSTRACT:
An inline oiler cartridge assembly for a pneumatically powered instrument includes a housing, a first conduit and a second conduit. The housing includes a lower portion removably attached to an upper portion. The lower portion defines an inner cavity and an outer cavity. A source of oil is disposed in the inner cavity. A dry fiber cellulose material is disposed in the outer cavity. The first conduit has a first end for attachment to a source of pressurized air and a second end for attachment to a pneumatically powered instrument. The first conduit passes through a portion of the upper portion of the housing and defines a channel for transmission of the source of pressurized air. The channel is in fluid communication with the inner cavity such that the source of pressurized air draws oil into an air stream for delivery to the pneumatically powered instrument.
