  • Page 48 Doc. No. ZQ-OM01301-C Countermeasures ■ Countermeasures Oil mist in the supply air or particles in the piping cause clogging if they enter the ejector. This may cause operation failure. Blow the air piping with air to eliminate particles. Installing the mist separator and air filter for cleaner supply air is recommended.
  • Page 49 Doc. No. ZQ-OM01301-C Countermeasures When the ejector adsorbs the workpiece by generating a vacuum, high speed air coming out of the nozzle collides into the diffuser I.D. and bounces back, generating vibration in the exhaust air. Because of this, the vacuum pressure fluctuates slightly and is not stabilized. The workpiece can be adsorbed when the ejector is used in this condition.
