Festo U-3/8 Pneumatic Silencer G3/8 5900L/min 10bar 82dB(A) 2309

Overview
The Festo U-3/8 (part number 2309) is a compact, high‑performance pneumatic silencer from the U series, designed for effective noise reduction at the exhaust ports of pneumatic components. This threaded silencer screws directly onto G3/8 ports, providing a simple yet efficient solution for reducing sound levels in industrial environments. It is an essential accessory for solenoid valves, cylinders, air motors, and other pneumatic equipment, helping to improve workplace conditions and protect sensitive components from debris.

Engineered for universal application, the U-3/8 silencer features a durable PE (polyethylene) silencing insert and a robust polymer housing, offering excellent corrosion resistance (CRC 1) and long‑term reliability. It operates reliably over a wide temperature range of -10 °C to +70 °C and a pressure range of 0 to 10 bar, making it suitable for a wide variety of industrial conditions.

With a high flow rate of 5900 l/min to atmosphere, this muffler minimizes back pressure while reducing noise levels to just 82 dB(A), effectively balancing performance and workplace comfort. Weighing only 30 g, it is one of the lightest and most compact solutions in its class, allowing for easy installation in tight spaces. The product is RoHS compliant and suitable for both lubricated and non‑lubricated compressed air systems.
