WARNING
!
Use clean dry air
Do not use compressed air which contains chemicals, synthe c oils containing organic solvents, salts or corrosive gases, etc., as
this can cause damage or malfunc on.
CAUTION
!
Install air filter
Install air filters close to valves at their upstream side. A filtra on degree of 5 μm or less should be selected.
Install an air dryer, a er cooler or Drain Catch (water separator) etc.
Air that includes excessive moisture may cause malfunc on of valves and other pneuma c equipment. To prevent this, install
an air dryer, a er‐cooler, or water separator, etc.
If excessive carbon dust is generated
Eliminate it by installing mist separators at the upstream side of valves. If excessive carbon dust is generated by the
compressor, it may adhere to the inside of valves and cause malfunc on.
