3.2. Air Supply
■Use clean air
(1) Using compressed air which contains chemicals, synthetic oils containing organic solvents, salts or
corrosive gases, etc. can cause damage or malfunction. Do not use compressed air containing toxic
impurities.
(2) If the compressed air contains excessive drainage or carbon powder, it can stick to the vacuum generating
part (the nozzle diffuser) or inside of the solenoid valve or the pressure switch for vacuum and cause
deterioration of the performance or operation failure.
(3) Quality of supply air
It is recommended to use compressed air which purity class is 2:6:3 of ISO8573-1:2010.
Supply air containing foreign matter, water, oil or condensate, etc. can cause malfunction of supply and
release valve.
It is recommended that an air filter and a mist separator are connected to the upstream side of the ejector
and the pump system to prevent foreign matter (drainage) from entering into the product, and perform
periodic maintenance of the mist separator to keep supply air quality.
