Abstract: A multi-component feed system to feed two fluid materials from a feed tank to a spraygun is described. The combined pressure feed tank comprises a pressure feed tank with a lid. Inside the tank is a removable support structure having a cone-shaped member with a central chamber supporting a second container closed by a lid. A splash-proof membrane extends between the inner wall of container and the outer wall of container to protect a second fluid component, e.g. a catalyst from entering the lower chamber of tank. Air is fed to containers and via a regulator, a regulator pipe and through an aperture in the lid. Pressure air feeds the fluid components via tubes to a spray gun, where the components combine to be sprayed.
