Multi-function air treatment unit

Abstract

This invention relates to a unitized air line filter and lubricator that includes provision for a pressure regulator therebetween that can either be by-passed or rendered operative by simply opening certain preformed passages in the manifold that connect same in series with the previously-mentioned components. The manifold houses nearly all of the working parts of both the filter and lubricator and their arrangement is such that the manifold can be reversed end-for-end to accommodate opposite directions of air flow. The subassembly that includes the bowls for the filter and lubricator along with the regulator spring therebetween in the three-component version will accommodate the manifold in either of its two positions and is, therefore, reversible relative thereto. Special sets of mounting brackets permit use of a single combination unit with air line piping of various sizes. These brackets also include a quick-disconnect feature wherein the entire combination unit can be detached therefrom and either serviced or replaced with another like unit in a very short time using only an allen wrench. The subassembly that carries the bowls includes a pair of quick-disconnect latches that are manually operated without any tools being required and which provide instant access to the bowls which are also removable.
