10 Series N Specific Product Precautions (Silencers) Be sure to read before handling. Design Warning 1. The exhaust port could become blocked by the clogging of the exhaust cleaner. Therefore, make sure to provide a safe design so as not to cause the whole system to malfunction. 1. The silencer is intended to reduce the noise of exhaust air of the compressed air emitted from pneumatic equipment. Noises other than exhaust air (noise generated inside piping, noise generated by vibration of equipment, noise of switching valves, etc.) cannot be reduced. Take appropriate measures to find the cause of noises other than those generated by exhaust air. 2. The inlet pressure obtained in the flow characteristic graph of silencer indicates the pressure (P1) prior to silencer. (Refer to the diagram below.) Solenoid valve Inlet pressure for silencer 3. 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. 4. The silencing effect could vary depending on the pneumatic circuit or the pressure that is used. Selection 1. Select a model which has a bigger effective area than that of the solenoid valve (including compound effective area). 2. Be certain to use at or below the level of recommended flow. P1 Silencer Mounting 1. If the silencer body (case) is made of plastic and is tightened too much, the silencer may be damaged. Please follow the procedures below for mounting. When the body (case) is made of resin Hold the tip of the main 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 1/4 turn. Tighten securely by hand for N For BC elements Hold the tip of the main body (the side without thread) with your fingers and screw it in tightly. Do not hold the sintered metal part with a wrench, etc. to tighten. When the main body is made of metal (Except BC elements) [Series 25] Within the recommended tightening torque shown in the chart below, use a wrench on the hexagonal flats and tighten. Tightening by using a pipe wrench or pliers may cause damage to the silencer. This method is not recommended. Tightening Torques for Silencers Connection thread R 1 4 pplicable tightening torque (N. m) 12 to 14 R to 24 R to 30 R to 30 R 1 R to to 42 R to 50 R 2 48 to Make sure not to apply a lateral load to the body during or after the installation. 3. When the main body of the silencer is loosened by vibration, etc. of equipment on which a silencer is assembled, apply glue to threads to prevent loosening and reattach. 4. Mounting metal rod accessories fter mounting the products with metal rods to the one-touch fitting, please do not replace the tube, resin plug, reducer, etc. It may cause loosening or detachment. pplicable products: N103-KM6, N103-X233, N103-X235, N203-KM8, N200-K8, N200-KM10, N300-KM10, N300-KM12 MC Maintenance MV 1. Never disassemble the silencer. MP The silencing material is not replaceable. 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. 607 N VCHN

14 Series VCHN Specific Product Precautions Be sure to read before handling. Warning Design 1. The exhaust port can clog due to a clogged or frozen silencer. Consider design safety to avoid malfunctions of the entire system. lso, under conditions conducive to freezing, use a freezereduction model. (VCHNF series) 1. silencer reduces compressed air exhaust noise from the pneumatic equipment. Noise other than that generated by the exhaust assembly (noise generated inside piping, due to equipment vibration, solenoid valve switching, etc.) cannot be reduced. s for noise generated by sources other than the exhaust, locate the cause and take measures. 2. Silencer inlet side pressure shows the solenoid valve supply pressure (P1). (See below.) 3. Noise reduction may vary, depending on the pneumatic circuit or pressure, etc. exhausted from solenoid valves. Selection 1. Select a silencer with a larger effective area (including the synthetic effective area) than the solenoid valve. P1 Valve Mounting 1. Tighten the silencer, using an appropriate wrench on the width across flats, within the range of the recommended tightening torque as shown below. Do not use a pipe wrench. Otherwise, the silencer will be damaged. Recommended Tightening Torque Connecting thread Torque 3/4 28 to to 38 Silencer 1 1/4 40 to 42 (Unit: N m) 1 1/2 48 to 50 Maintenance 1. When exhaust speed begins to slow from clogging and system functionality begins to degrade, replace with a new silencer or sound-absorbant material. lso, be sure to confirm the actuator's operation status once per day. How to Replace the Sound bsorbing Material 1. When replacing the sound absorbing material, please follow the instructions below. Hexagon bolt Tighten the screw with a torque of 20 to 25 N m after applying an anti-loosening agent. lso, the antiloosening agent is recycleable.
