AirCraft Plastic Breather Silencer 3/4" BSP Male Blue (SG PSU-20)
At a Glance: 3/4" BSP male plastic breather silencer—reduces pneumatic exhaust noise and helps keep venting cleaner.
Big ports move a lot of air—and when that air vents, it can get properly loud. The AirCraft SG PSU-20 Plastic Breather Silencer helps soften pneumatic exhaust noise by diffusing the outgoing air, making high-flow valve and manifold exhaust noticeably quieter and more workshop-friendly. With a 3/4" BSP male thread and a lightweight plastic body, it suits many pneumatic exhaust and vent points on valves, manifolds, regulators and air equipment where a breather/silencer is required. It’s a simple part that does an underrated job: reduce noise, keep venting cleaner, and make the whole system feel more civilised.
Designed to diffuse exhaust air on larger BSP ports, helping reduce harsh vent noise while acting as a breather-style outlet in everyday industrial environments.

Features
- 3/4" BSP male thread Fits compatible pneumatic exhaust/vent ports using BSP fittings.
- Breather silencer design Helps diffuse escaping air to reduce exhaust noise.
- Lightweight plastic body Corrosion-resistant and easy to fit and replace.
- Blue colour Quick visual identification in pneumatic installations.
- Suitable for larger ports Useful on higher-flow exhaust points where noise is more noticeable.
Benefits
- Quieter operation: Reduces exhaust noise from high-flow pneumatic valves and manifolds.
- Cleaner vent points: Helps minimise dust and debris ingress at exhaust/vent locations.
- Easy maintenance: Quick to install and replace as part of routine pneumatic servicing.
Extra Information
- Commonly fitted to pneumatic manifold/valve exhaust ports, regulator vents and industrial air circuits.
- Confirm your port is 3/4" BSP female before installation.
- In dusty environments, breathers can clog over time—inspect periodically and clean/replace as needed.
- Admin info (not for specs table): Confirm product weight and dimensions from your database / packaging.
Pro Tip
- If your exhaust is still loud, consider adding silencers to all exhaust ports and ensure there’s no restriction upstream forcing the system to vent aggressively.
Safety
- Always depressurise the air system before installing or removing pneumatic fittings.
- Confirm correct thread type (BSP) and avoid cross-threading during installation.
- Do not use a blocked or damaged silencer—restricted exhaust can affect system performance.
- Wear eye protection when working with compressed air lines and venting components.
