A purification unit is described, which is suitable for the purification of a compressed fluid containing a contaminant, comprising a purification vessel (12) having an inlet (22) and an outlet (24) and a particulate purification material (26) capable of undergoing a colour change in reaction with said contaminant, disposed within said vessel such that a fluid entering the vessel through said inlet may pass through said particulate purification material and exit the vessel through said outlet, wherein the vessel has one or more window portions (20) aligned in the direction of fluid flow through the vessel enabling a user to observe a colour change in the particulate. purification material, wherein the vessel is fabricated from a fibre-reinforced polymer composite having one or more transparent window portions. |
