Can cylinders and valves from Festo also be operated with unlubricated compressed air?
In terms of their materials and processing, most Festo pneumatic components are designed for operation with filtered, lubricated compressed air or filtered, unlubricated compressed air. These components are subject to basic lubrication during assembly and can therefore be used without a lubricator In all cases, a filter unit is required that removes contaminants of 40 microns. Where “filtered, unlubricated compressed air” is indicated as the medium for components, Festo subjects them to a random tests using filtered, unlubricated compressed air under test conditions. Filters with a degree of filtration of 5 or 10 microns should be used when required by the technical specifications. In the case of highly contaminated air we recommend pre-filtering the air using a 40 micron filter. We recommend operation with filtered, lubricated compressed air in places subject to extreme environmental and operating conditions, such as where extremely fast cylinder movements are performed (over 2 m/s).
