This spray gun system made of high-quality stainless steel makes it possible to take the water or compressed air gun apart and thus prepare it properly for further use. All parts of the spray gun can be easily disassembled without any tools, are suitable for cleaning machines and can be sterilised. Because they are made of stainless steel, the guns can also be used with demineralised water. This makes them suitable for use in various contexts, such as the sterilisation centre or endoscopy department.
