Metal Silencers

The API Metal Silencers are noise reducers for compressed air systems, manufactured from aluminium, galvanized steel, and stainless steel. This series offers a wide range of models for various applications, including single and multi-chamber designs, equipped with noise-absorbing cartridges and safety valves for pressure regulation. The silencers are available in sizes from 1/8″ to 6″ and support BSP taper threads. They are suitable for pressures up to 12 bar (standard) or 40 bar (with /40 option) and a temperature range of -25°C to +120°C. Ideal for large installations, air dryers, and systems sensitive to pressure pulsations.

Advantages

  • Durable materials such as aluminium, galvanized steel, and stainless steel.
  • Balance valve in MR and MD for automatic pressure regulation and damage protection.
  • Dust-resistant cartridges (MD) for air dryer applications.
  • High-pressure option (/40) up to 40 bar for demanding environments.
  • Easy installation and maintenance with replaceable cartridges.
  • Wide range of sizes from 1/8″ to 6″ for flexible installation.
  • Complies with industrial standards for safety and performance.
  • Suitable for diverse applications, from small systems to large industrial installations.
