Compressed air for valve outlets
You should operate the valves with filtered (40 m m), dried and oil-free compressed
air of Class 5 4 3 in accordance with ISO 8573-1.
Operation with filtered, dried and oiled compressed air of Class 5 4 5 is similarly
possible. For this purpose, use an oil that is included on FESTO’s list of proposed
oils:
