Pulsation/Pulsation is decreased with a tank.
If the outlet capacity is undersized, pulsation may
occur.
Conditions:
Inlet pressure: 0.5 MPa
Outlet set pressure: 1 MPa
Flow rate: Between 0 and max. flow rate

•
Performance of air tank
• Alleviates the pulsation generated on the
outlet side.
• When air consumption exceeds air supply
during intermittent operation, required air
will be accumulated in the tank for use.
This does not apply for continuous
operation.
