40 dB (A) High Noise Reduction Silencer, ANA1 Series (ANA1-20)

SMC

[Features]
· High noise reduction silencer that achieves 85 dB (A) or lower when tested in our factory.
· Fluid: compressed air.
· Maximum operating pressure: 1.0 MPa (*Shows the primary-side pressure of the solenoid valve).
· Noise reduction effect: 40 dB (A) (*May change depending on the air pressure circuit, pressure, etc., from which the exhaust is emitted).
· Ambient temperature and operating fluid temperature: 5 to 60°C.
*Can be used at between -10 to +60°C as long as there is no risk of water drops being generated from the fluid and freezing.
