1. System configuration
• The IN port of the booster regulator has metallic mesh to prevent
dust from entering the booster regulator. However, it cannot
remove dust continuously or separate drainage. Make sure to
install a mist separator (AM series) on the inlet side of the
booster regulator.
• The booster regulator has a sliding part inside, and it generates
dust. Also, install an air purification device such as an air filter or
a mist separator on the outlet side as necessary.
• Connect a lubricator to the outlet side, because the accumulated
oil in the booster regulator may result in a malfunction.
2. Exhaust air measures
• Provide a dedicated pipe to release the exhaust air from each
booster regulator. If exhaust air is converged into a pipe, the
back pressure that is created could cause improper operation.
• Depending on the necessity, install a silencer or an exhaust
cleaner on the exhaust port of the booster regulator to reduce
the exhaust noise.
3. Maintenance space
• Allow the sufficient space for maintenance and inspection.

Note 1) If the OUT pressure is higher than the set pressure by the handle, excess pressure is exhausted from the back of the handle.
Note 2) Flow rate at IN= OUT= 0.5 MPa. The pressure varies depending on the operating conditions. Refer to “Flow-rate Characteristics” on pages 926 and 927.
