The Ross 5500A7013 Pneumatic Silencer Muffler is a compact exhaust silencer designed for attachment to 1-1/4 in NPT male ports, used to quiet the exhaust from valves, cylinders, and pneumatic actuators. Model 5500A7013 (D5500A7013) measures about 5.5 in long (140 mm) and weighs roughly 0.6 lb (0.3 kg), making it suitable for space‑constrained installations. Rated for service up to 150 psi (10.3 bar), this silencer is part of Ross Controls’ 5500A‑series exhaust silencers and is ideal for reducing noise in automated systems and industrial pneumatic equipment where venting occurs.
