Precautions for Design
Warning
(1) Consult SMC if no leakage is allowed due to the environment, or if the operating fluid is not air.
(2) Polycarbonate resin is used for the external parts including the bowl. Organic solvents including
thinner, acetone, alcohol and ethylene chloride; chemicals including sulphuric acid, nitric acid and
hydrochloric acid; cutting oil, synthetic oils, ester-based compressor oil, alkali, kerosene, gasoline,
lock material of screw are harmful. Do not use the product where these are present.
Chemical resistance of polycarbonate and nylon bowl
When the above factors are present or there is some doubt, use a metal bowl for safety.
(3) Shield from ultra violet light and radiation with protective cover.
