Fisher CASO | Compressed Air System Optimisation
Ultrasonic Compressed Air
Leak Detection Services
Find the hidden losses that compressor controls cannot explain. As an official distributor of Synergys Technologies, Fisher uses LeakShooter visual ultrasonic equipment to locate, document, and prioritise air leaks across your plant.
Loss control
Expose hidden air leaks before they become permanent operating costs.
Leaks consume generation capacity 24/7, drop system pressure at point-of-use equipment, and make expensive additional compressor capacity appear necessary before it truly is.
Assessment Methodology & Site Protocol
Our survey follows Fisher's strict leak detection methodology to ensure complete accuracy without interrupting production.
- Confirm induction, permit and area access with site management
- Complete task risk briefing and review plant movement and photography rules
- Pre-use inspection of visual ultrasonic camera, headphones, tags, and accessories
- Systematic scanning along approved production routes
- Safe tagging and authorised photography only; no reaching through guarding or interference with live equipment
- Record leak data (location, tag number, dB reading, photograph reference, component type)
- Site close-out, housekeeping, access limitations, and handback to client site management
Typical Leak Survey Findings & Classifications
| Component Category | Common Location | Typical dB Reading | Corrective Action |
|---|---|---|---|
| Pneumatic Push-in Connectors | Machine drop-offs, valve manifolds | 15 – 35 dB | Re-seat tubing or replace connector fitting |
| Filter Regulator Lubricators (FRLs) | Machine air preparation units | 30 – 55 dB | Replace housing seals or auto-drain assembly |
| Isolation & Ball Valves | Distribution pipework drop legs | 20 – 45 dB | Re-seal threads with PTFE tape or replace valve |
| Solenoids & Actuators | Automation cells, pneumatic transport | 25 – 60 dB | Service internal seals or replace actuator unit |

Frequently asked questions
Compressed air leak detection FAQs
How much energy does a typical compressed air leak waste?
A single 3 mm leak operating at 7 bar can waste significant electrical power continuously. In an unmonitored plant, minor leaks often add up to over 20% to 30% of total generation capacity.
Can an ultrasonic leak survey be conducted during normal factory operation?
Yes. High-frequency ultrasonic detectors isolate the acoustic signature of escaping compressed air from ambient machinery noise, allowing full surveys while production continues uninterrupted.
What safety and risk controls are followed during the survey?
Fisher follows an approved Method Statement and Safety Plan. Before work starts, technicians complete site induction, task risk briefings, and Daily Safe Task Instructions (DSTI). Technicians remain outside machinery guarding and clear of operating plant.
