In addition, the exhaust port should not be blocked or pressurized.
If the sound absorbing material is clogged, it will cause a reduction in the ejector performance.
Sometimes, if the operating environment contains a lot of particles or mist, the replacement of the filter
element only is not enough to recover vacuum performance
– as the sound absorbing material may be
clogged. Replace the sound absorbing material. (Regular replacement of the filter element and sound
absorbing material is recommended.)
■
Exhaust Noise
When vacuum ejector generates vacuum, noise can be heard from the exhaust port when the standard
supply pressure is close to the pressure that generates peak vacuum pressure making vacuum pressure
unstable. If the vacuum pressure range is adequate for adsorption, there should not be a problem. If the noise
causes a problem or affects the setting of the pressure switch, change the supply pressure slightly to avoid
the pressure range of the noise.

Maximum Number of Manifold Stations that Can Operate Simultaneously
Note)
Note) As long as the number of stations operated simultaneously is the value on the table or less, then the manifold is
available up to 10 stations.
