N Specific Product Precautions Be sure to read before handling. Refer to back cover for Safety Instructions. Warning esign. The silencer clogging may result in a blocked exhaust port. Provide a safety design so as not to cause the whole system to malfunction.. 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. o not use the product as a filter regardless of negative and positive pressures.. 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. Selection. 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 3 /(s bar)] = Effective area [mm ]. Use within the range of specifications. Operating Environment Warning. o 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.. void exposure to direct sunlight. 3. o not operate in locations where vibration or impact occurs. 4. o not use the product in locations where it is near heat sources and exposed to radiation heat.. o 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. o 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. Silencer Tightening Torque (Metal type) Connection thread R 3/4 R R /4 R / R Mounting. If the silencer body is made of resin and is tightened too much, the silencer may be damaged.. 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. t the point where the thread begins to feel tight, use a wrench on the hexagonal flats to tighten an additional /4 turn. Tighten the N0-M 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. N m or less.) Silencer 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. pplicable tightening torque N m 8 to 30 36 to 38 40 to 4 48 to 0 48 to 0 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. Maintenance. The sound absorbing material is not replaceable. Since the sound absorbing material is not replaceable, never disassemble the product.. 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.
