AquaDriver manufactures cutting edge self cleaning heads for protein skimmers. Manufactured in Germany with quality second to none, the AquaDriver self cleaning heads feature innovations not found in any other self cleaning heads. All AquaDriver self cleaning heads include a dual wiper system that cleans both the neck and lid. Our revolutionary wet wiper system insures efficient cleaning of the neck and lid by drawing water up from inside the skimmer body and spraying it onto the neck and lid. An optional washdown system allows users to flush the inside of the collection cup for easy cleaning without ever having to remove the cup.
