The hobby series consists of oilless air compressors designed for D.I.Y. enthusiasts. Compressors without air collection tanks and also compressors with tanks from 6 - 25 and 50 liters for a more intensive use, but all without maintenance requirements. Thanks to the compact and safe constructional design and to the reduced weight, these compressors may be easily used and transported anywhere by anybody. They are complete with a pressure reducer and electrical lead with plug ready for immediate use. The housing in shock proof material safeguards the user from exposure to the internal rotating components and hot surfaces.
