Overview
The Festo 552252 UOS-1 silencer is a compact pneumatic muffler engineered to reduce exhaust noise in compressed air systems. Built with durability and efficient noise control in mind, this open-design silencer handles operating pressures from 0 to 10 bar and is compatible with Festo soft-start valve series (MS-SV). The unit features a G1 male threaded connection for straightforward integration into existing pneumatic networks.
