this case, oil mist will be generated. Replace the element.
!
NOTE
Replace the element if it is clogged with dust or the like. Otherwise, oil mist may be
discharged.

Do not plug the exhaust port nor operate the unit with a device that interferes with the
passage of a gas connected to the exhaust port. The internal pressure of the oil mist trap
will rise and the unit may be damaged or fail.
