SMC NAN300-N03 Muffler

SMC NAN300-N03 muffler is a compact silencer in the NAN SILENCER family for 3/8" NPT exhaust ports, engineered to quiet pneumatic exhaust while preserving flow. It supports up to 1 MPa (145 psi) and operates in ambient temperatures of 5–60°C (40–140°F). With an effective orifice of 60 mm² (Cv ≈ 3.3), it delivers 30 dB or more of noise reduction and is designed to maintain low back pressure in the exhaust line. Dimensions are 84 mm long (A), 25 mm wide (B), and 22 mm deep (D), making it a space-saving option for compact installations. This model is NAN300-N03 for standard 3/8" NPT ports and belongs to SMC's NAN silencer series, which emphasizes easy mounting and reliable performance in typical factory automation environments. Its quieting capability suits exhausts from pneumatic actuators, cylinders, and control valves in automation equipment and robotics where noise reduction is a priority, and is suitable for space-constrained installations in tight enclosures.
