1\For the air filters, filter regulators and lubricators which water bowls, oil bowls and oil windows are made of polycarbonate:

1) They can not be used in the medium or circumstance below:

Acid (hydrochloric acid, vitriol, phosphate, chromate), Alkali (Sodium hydroxide, Potassium hydroxide, autunite hydroxide, ammonia, sodium carbonate), Inorganic salt ( sulfureted sodium, Niter, Glauber's salt).Chlorin impregnant (tetrachloride, chloroform, chloridize ethane, chloridize methylene),Aromaticity(Benzene,cycloparaffin,enol).Ketone(Acetone, butyltone).Alcohol(alcohol, carbinol),oil(gas, coal oil, alkalescence water-solubility cutting liquid),Ester,Aether,Amine,Screw encapsulant,seawater.

2\In order to avoid too much pressure fall, the outlet pressure should be controlled lower than 85% of inlet.

3\If the air flow is not enough, the lubricator will not drop the oil. So the air flow of the lubricator must be satisfied for the oil drop requirement.

4\The oil of the lubricator must be Turbine No.1 Oil ISOVG32.The components will be destroyed if you use another kind of oil.
