  • Page 20: Handling Precautions

    Doc. no. DOC1058584 11.Handling Precautions 11.1. Exhaust from the Ejector The exhaust resistance should be as small as possible to obtain the full performance of the vacuum ejector. There should be no shield around the exhaust port for the silencer exhaust specification. Sound absorbing material is gradually clogged in the following cases: - Suction of dust in the environment at the time of adsorption, or - When the air is not clean enough.

  • Page 22 Doc. no. DOC1058584 ■Countermeasures Countermeasure Oil mist in the supply air or particles in the piping cause clogging if they enter into the ejector. This may cause operation failure. Blow the air piping with air to eliminate particles. As a further supply air cleaning measure, install a mist separator and an air filter.
  • Page 23 Doc. no. DOC1058584 Countermeasure When the product suctions a workpiece by generating a vacuum, high speed air coming out of the nozzle collides into the diffuser’s inner diameter 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 suctioned when the ejector is used in this condition.
