The fitting is provided at nozzle surfaces of the nozzle made of plastic, where the nozzle surfaces are turned towards a surface to be sucked or are brought in contact with the surface to be sucked during suction. The fitting comprises a material, which has biocide effect. The fitting comprises a surface coating, where the coating or a material component of the nozzle is based on a hybrid complex material e.g. silver, silver compounds, copper or copper compounds. |
