<p>Pressurised fluid driven cleaning equipment in the form of a paint application spray gun cleaner (10) comprises a cleaning hopper (12) enclosing a cleaning chamber (14), a heavy duty injection flushing nozzle (16) onto which a spray gun (18) is mountable for interior flushing, an interior and exterior spray gun cleaning liquid washing layout (22) for spray gun secondary cleaning and washing, a pneumatically driven pump (28), an agent vessel (30) and a spent agent collection hopper (38). The hoppers (12, 38) are clo sable against escape of agent fumes during use by way of lids (36, 46) reopenably closing off boxes (34, 44). The equipment is fit ted with fluid flow selction valves (48, 80 and 86). The valve 80 is used for changing the pump (28) from suction to agent ejection, the valve 48 for switching the cleaning process between the nozzle (16) and the layout (22) and the valve (86) for selecting either agent or pressurised air during the cleaning process.</p> |
