Standard mufflers
Festo's pneumatic muffler range is designed to cater to various operational needs, ensuring users can find the right solution for their specific applications. Table 1 provides valuable insights into four different series of Festo pneumatic mufflers: the U series, UC series, AMTE series, and UOS-1 series.
- Noise reduction: The noise reduction levels, measured in decibels (dB(A)), indicate how effectively each muffler can lower the sound produced by the exhaust air, with lower values representing better noise attenuation.
- Flow rate: Flow rate, measured in liters per minute (l/min), shows the volume of air that can pass through the muffler, which is crucial for maintaining system efficiency and performance.
- Material composition: Material composition details the construction materials used in each series, such as sintered metal, polymers, brass, and bronze, which affect durability, resistance to environmental conditions, and compatibility with other system components.

High-performance mufflers
Festo's high-performance pneumatic mufflers work particularly with VN-T2 and VN-T3 vacuum generators. Table 2 outlines three specific types: the UO series pneumatic mufflers, the UOM series pneumatic mufflers, and the UOMS series pneumatic silencer extensions. Each type is crafted from high-quality materials, such as polyethylene, polyacetal, wrought aluminum alloy, and polyurethane foam, contributing to their durability and effective noise attenuation. The UO and UOM series are designed to be easily screwed into place, while the UOMS series offers engaging mounting for added convenience. By integrating these high-performance mufflers with VN-T2 and VN-T3 vacuum generators, users can achieve optimal noise reduction and maintain the efficiency of their pneumatic systems.

Pneumatic filter mufflers
A pneumatic filter muffler, such as Festo's LFU series, serves a dual purpose in pneumatic systems: it reduces the noise generated by exhaust air and filters out contaminants to protect the system's components. Table 3 highlights several key features of the LFU pneumatic filter muffler. With a filtration efficiency exceeding 99.99%, it effectively removes oil and other contaminants from the exhaust air, ensuring cleaner operation and prolonging the system's lifespan. Festo also offers the LFPU filter cartridge as an essential replacement part for the pneumatic filter muffler.
Table 3: Festo's LFU pneumatic filter muffler
| Feature | Description |
| High filtration efficiency | >99.99% removal of oil and contaminants |
| Noise reduction | Reduces exhaust noise by 40 dB(A) |
| Condensate collection | Collected in the lower plastic bowl, manually drained |
| Material composition | Polypropylene (PP) housing |
| Operating conditions | Suitable for 0 to 16 bar pressure, -10°C to +60°C temperature |
| Mounting | Designed for vertical mounting with a tolerance of ±5° |

Pneumatic muffler throttle valves
A pneumatic muffler throttle valve both reduces exhaust noise and regulates airflow, thereby enhancing system efficiency and performance. Table 4 overviews three series of Festo's pneumatic muffler throttle valves: the GRU, GRE, and VFFK series. Each series features different adjustable components, such as slotted head screws or knurled screws, which allow for precise control over airflow. The material composition varies across the series, indicating the durability and suitability for different applications. The screw-in mounting method facilitates easy installation, while the standard nominal flow rate, ranging from 80 to 8,000 liters per minute, provides insight into the capacity and suitability of each valve for different flow requirements.
