Festo's silencers, models AMTE, U, and UC, are designed to optimize pneumatic systems by reducing noise and preventing contamination. The metal AMTE is available in long or short constructions, specifically for compressed air. The smaller U model is offered in plastic or die-cast metal, with quick-connect barb or threaded fittings. The UC, exclusively in plastic, is ideal for reducing noise and preventing contamination in exhaust connections, also operating with compressed air.
