Silencer Silencer
Design Mounting
Warning Caution
1. The silencer clogging may result in a blocked exhaust
port.
Provide a safety design so as not to cause the whole system to
malfunction.
Selection
Caution
1. When selecting the silencer, the sonic conductance∗
(including combined sonic conductance) of the silencer
should be larger than that of the solenoid valve.
∗Sonic conductance C [dm

/(s·bar)] = Effective area [mm
2
] ÷ 5
2. Use within the range of specifications.
Operating Environment
Warning
1. Do not use in an atmosphere having corrosive gases,
chemicals, sea water, water, water steam, or where
there is direct contact with any of these.
Refer to the construction drawings for silencer materials.
2. Avoid exposure to direct sunlight.
3. Do not operate in locations where vibration or impact
occurs.
4. Do not use the product in locations where it is near heat
sources and exposed to radiation heat.
5. Do not use in an environment where the product is
exposed to cutting oil, lubricating oil, or coolant, etc.
If it is used in an environment where there is possible contact with
cutting oil, lubricating oil, or coolant, exercise preventive measures.
6. Do not use in an environment where foreign matter may
stick to the product or get mixed in the product’s interior.
It may result in clogging at an early stage, coming off or causing
damage.
Caution
1. The silencer is intended to reduce the noise of
compressed air that is exhausted from the pneumatic
equipment.
Since noises generated by sources other than the exhaust, such
as noise generated inside piping, equipment vibration and
solenoid valve switching, cannot be reduced, locate the cause of
these noises and take countermeasures.
The product does not function as a filter. Do not use the product
as a filter regardless of negative and positive pressures.
2. If the compressed air supply is contaminated with fluids
such as oil and oil mist, such fluids will be dispersed to
the environment.
In such a case, an exhaust cleaner is recommended to recover
fluids and reduce noise.
3. The value of the noise reduction may vary, depending
on the pneumatic circuit or pressure that is exhausted
from the solenoid valve.
1. If the silencer body is made of resin and is tightened
too much, the silencer may be damaged.
2. Tightening by using a pipe wrench or pliers may cause
damage to the silencer. This method is not
recommended.
Please follow the procedures below for mounting.
 When the body is made of resin
Hold the tip of the body (the side without thread) and screw it in.
At the point where the thread begins to feel tight, use a wrench
on the hexagonal flats to tighten an additional 1/4 turn.
Tighten the AN05-M5 by hand completely until the ends of the
fitting come into contact with the mounting surface. Then apply
additional tightening. Note that the additional tightening should
be 30° or less. (Tighten it with 0.1 N·m or less.)
 When the body is made of metal
Within the recommended tightening torque shown in the table
below, use a wrench on the hexagonal flats and tighten.
Maintenance
Caution
1. The sound absorbing material is not replaceable.
Since the sound absorbing material is not replaceable, never
disassemble the product.
2. If the exhaust speed drops and the system performance
decreases due to clogging, replace with a new silencer.
Make sure to verify the operating conditions of the actuator at
least once a day.
3. If operation continues when it is clogged, breakage
can result.
3. Make sure not to apply a lateral load to the body
during or after the installation.
4. When the silencer body is loosened by vibration, etc.
of equipment on which a silencer is assembled, apply
glue to threads to prevent loosening and reattach.
