The LubroStar®-System consists of a robust special steel pressure tank, an infinitely adjustable dosage device, and the LubroStar®-Synthetic Activator (LSSA). This synthetic lubricant and de-icing agent, which is added to the compressed air, has been developed to meet the exact requirements of compressed-air-operated tools and machines. Choking of the system is prevented by a suitably disposed pipe system and large cross-sections, and simultaneously even the smallest quantities of LSSA can be supplied in the compressed air. Extremely small quantities can be dosed and suitably atomized by appropriate adjustment of the dosage device. It is also possible to alter the dosage during operation. The LSSA supply can be reduced or increased without interrupting the operation. Incidentally, any synthetic lubricant and de-icing agent can be dosed with the LubroStar® maintenance system. However, numerous tests and practical application have shown that the best results are achieved with LubroStar®-Synthetic Activator.
