The OU series of Festo type Air treatment units usually consist of OFR(Filter and Pressure Regulator),OL(lubrication), each of them can be used and purchased separately. Regarding the OFR,the Filter is used for filtering the dirt and some particles,then after the filtration,the air will be clean and dry. And there are usually different levels of filtration,such as the precision can be 40 micron,5 micron and so on. Meanwhile,the regulator is used for regulating the pressure of air source. As for OL(lubrication),it plays an important role in promoting the equipment works more smoothly and stably.
