Long Pneumatic Silencer | Aignep

The AIGNEP 7000 Series Long Pneumatic Silencer — Ref. 0703000004, 3/8" BSPT Thread is made of sintered bronze with a high-resistance metal body, designed to efficiently reduce noise generated by compressed air discharge in industrial valves, cylinders, and pneumatic systems. Its long design offers a larger filtration surface and better acoustic reduction compared to short models, with minimal pressure drop. In addition to noise reduction, it retains particles and contaminants in the exhaust, protecting the environment and system components. Direct installation into 3/8" BSPT threaded exhaust ports. Manufactured in Italy by AIGNEP.

Long vs. Short — When to use the long silencer?

• Long silencer (this model): Larger sintered bronze surface — better acoustic reduction. Ideal for higher flow valves or environments with more stringent noise requirements.
• Short silencer: Smaller size for confined spaces. Standard acoustic reduction for lower flow applications.

Applications

• Exhaust ports in solenoid valves and directional valves (01V, 08VS Series, etc.)
• Single and double-acting pneumatic cylinders
• Pneumatic machinery and industrial process equipment
• Production lines and automation where acoustic pollution reduction is required
• Any pneumatic system with a 3/8" BSPT threaded exhaust port
