Overview
SMC ANA1-02 is a high noise reduction pneumatic silencer engineered for industrial compressed air systems. The ANA1 silencer keeps the noise level inside a plant below 85dB(A) with a noise reduction effect of 40dB(A). With a 1/4 BSPT port size and overall length of 64 mm, this compact muffler provides effective exhaust silencing in space-constrained installations. The screw-in design enables quick, tool-free replacement on existing pneumatic circuits.
Key Features
- High Noise Reduction: Provides significant noise reduction of up to 40 dB(A), bringing plant noise to industrial-acceptable levels
