Compressed air preparation

Festo compressed air treatment essentially comprises of air units that can be coupled, such as filter regulators, filters, pressure regulators and oilers, which are combined with switch-on valves/pressure build-up valves and distributors into air units. The most frequently used air unit is a combination of filter regulator and oiler (often also called "FR-L" or 2-piece air unit). Since, in many applications, adding oil is not necessary or even harmful, the oiler is often dispensed with and only a filter regulator is used. At a filter or a filter regulator, the condensate can be drained through automatic drain valves, but must not reach the water drains in that state. We recommend oil-water separators.
