AN40-N04 Applications

The AN40-N04 is a larger compact resin exhaust silencer with a 1/2 NPT male thread and higher flow capacity (effective area 90 mm2). It reduces pneumatic exhaust noise by 30 dB(A) while keeping back pressure low, suiting larger valves, cylinders, and manifolds in NPT-piped factory automation. The UL94-V0 flame-resistant case supports quieter, cleaner compressed-air discharge in industrial installations.
