Customer information regarding material resistance in compressed air preparation Polycarbonate reservoirs for filter regulators, filters, and lubricators Everywhere the presence of these media cannot be avoided, such as in paint booths, gluing machines, Polycarbonate is the longest known and most vulcanization plants, etc., the use of metal reservoirs processed material in the world for reservoirs of is required. compressed air maintenance units. The high Problematic is the use of solvents not only in pressure and temperature resistances, as well as immediate contact with the reservoir, but also in its good compatibility with the normally used media immediate vicinity. For example, trichlorethylene such as water, oils and greases are some of its vapors from the compressor’s intake air can cause advantages. crack formation in the polycarbonate reservoir. Only The only “weakness” of this plastic is its clean the reservoirs using a slightly damp cloth. Only susceptibility to media that can be referred to use water to do this and, if necessary, a mild collectively using the term “solvents”. From this detergent without chemical additives. range, the materials relevant to the use of If a lubricator is used, please only use suitable compressed air preparation units are summarized pneumatic oils, e.g. AVENTICS pneumatic oil, order here: no. 8982000010 – 1L. Detergents : Trichloroethylene, (usually from outside) perchloroethylene, In most cases, the use of (pneumatic) oils with benzene, additives, for example antifreeze, results in damage super/regular gasoline to or destruction of the reservoirs and must thus be avoided. Alternatively, we recommend the use of Solvents : Acetone, metal reservoirs. (from outside/inside) paint thinners, alcohols, esters Polycarbonate can react to permanent UV-light irradiation and weathering. The degree of sensitivity Other media : Synthetic oils, drilling depends to a large extent on the intensity and oil, high-alloyed oils duration of irradiation and the weathering (car engines), certain conditions. compressor oils, anti- freeze, brake fluid, ammonia, different bonding and sealing agents, plasticizers, coolants, lubricants R412025273-DBL-002-AB/2016-07, Subject to modifications. © All rights reserved by AVENTICS GmbH, even and especially in cases of proprietary rights applications.
