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.

Standout feature: High-flow vent silencing with a 3/4" BSP male connection

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.

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.

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.

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.
