Compressed air engineering services
Measure the system.
Make the next decision clear.
Fisher Installations turns flow, power, pressure, air quality, and field observations into practical actions for maintenance, production, and engineering teams.
What we investigate
A measured view of how your compressed air system is really performing.
Individual tests answer focused questions. Combined measurements reveal how generation, treatment, distribution, and demand interact across the plant.
Fisher CASO | Compressed Air System Optimisation
Find the losses that compressor controls cannot explain.
Leaks consume generation capacity around the clock, reduce pressure at the point of use, and make additional compressor capacity appear necessary before it truly is. As an official distributor of Synergys Technologies, Fisher uses LeakShooter visual ultrasonic equipment to locate, document and prioritise these losses.
Request a leak surveyHow we do it: the Fisher CASO Framework
The Fisher Compressed Air System Optimisation (CASO) Framework connects safe field inspection, system measurement, analysis, prioritised action and verification. For leak surveys, it follows Fisher's approved leak-detection method statement and risk controls. Before scanning, we confirm induction, access, permits where required, emergency arrangements, photography rules and the daily safe task instruction. We inspect the LeakShooter, headphones, tags and supporting equipment, then move systematically through approved areas while remaining outside guarding and clear of traffic and operating plant.
- Site induction, task risk briefing, DSTI and area inspection before work starts
- Pre-use inspection of the visual ultrasonic camera, headphones, tags and accessories
- Systematic scanning of approved routes, with work stopped if conditions differ from the assessment
- Safe tagging and authorised photography only; no reaching through guarding or interference with live equipment
- Leak location, tag number, dB reading, image reference and field observations captured for reporting
- Close-out, housekeeping, access limitations and unsafe conditions handed back to the client
A prioritised leak register with photographic evidence, location and tag references, readings, repair guidance, stated estimating assumptions and potential financial impact.
Flow demand analysis
See when, where, and how much air the plant actually uses.
Nameplate capacity does not describe a changing production load. A measured demand profile helps distinguish genuine process demand from waste, peaks, and artificial demand.
Discuss flow loggingHow we do it
Flow instruments are selected and installed at suitable measurement points, then logged across representative shifts or production cycles. We align the resulting profile with operating events so the numbers describe what was happening in the plant.
- Baseline, average, peak, and off-production demand
- Production-cycle and shift comparisons
- Capacity, storage, and compressor-control insight
- Evidence for isolation, optimisation, or future expansion
A time-based demand profile with peak events, base load, utilisation patterns, and engineering observations.
Compressor efficiency testing
Compare the air delivered with the power consumed.
A compressor may run reliably while delivering less air per kilowatt than its design condition. Measuring flow, power, and pressure together reveals the real efficiency gap.
Scope an efficiency testHow we do it
We measure delivered flow, electrical input power, and operating pressure under representative conditions. Specific power is calculated and, where design data is available, compared with the compressor's specification sheet to quantify the performance difference.
- Simultaneous flow, power, and pressure measurement
- Specific power calculation in kW per delivered flow
- Comparison with available original design data
- Performance gap and operating-condition commentary
An efficiency test record showing measured conditions, calculated specific power, and design comparison.
Pressure profiling
Trace pressure problems through time and across the network.
Raising discharge pressure can hide a distribution problem while increasing energy use. Pressure profiles show where instability begins and whether it follows demand, controls, or restriction.
Investigate a pressure issueHow we do it
Pressure is logged at selected compressor-room and point-of-use positions over a representative operating window. Multiple traces can be correlated with flow and production activity to identify pressure drop, control-band behaviour, and short-duration events.
- Compressor room and critical point-of-use logging
- Pressure drop and instability identification
- Demand-event and control-response correlation
- Evidence for distribution or storage improvements
Pressure trend charts with event analysis, network observations, and prioritised next checks.
Compressed air quality testing
Verify the air conditions reaching critical processes.
Moisture, particles, and oil-related contamination can affect product quality, equipment life, and process compliance. Assumptions at the compressor room do not prove conditions at the point of use.
Plan an air quality testHow we do it
We agree critical sampling points and test parameters against the site's process requirements. Testing can include pressure dew point, particle, and oil-related assessment in an ISO 8573-focused context, with conditions and limitations recorded alongside the results.
- Critical point and risk-based sampling plan
- Pressure dew point and applicable contaminant testing
- Results interpreted against the agreed requirement
- Traceable records of location and operating condition
A test report with measurement points, methods, results, and requirement-based interpretation.
Independent desiccant sample testing
Test the media before committing to an expensive replacement.
Desiccant condition cannot be judged reliably by service age alone. Independent sample testing adds evidence to a high-cost replace-or-retain decision and is rarely available locally.
Arrange a sample testHow we do it
Representative media samples are collected or received with the dryer and operating context. The sample is assessed for condition and relevant contamination indicators, then interpreted to support a reasoned recommendation rather than an automatic replacement interval.
- Representative sampling guidance and sample traceability
- Independent condition and contamination evidence
- Operating context considered with test findings
- Replace, retain, or investigate-further recommendation
A concise independent condition report to support the next dryer maintenance decision.
Industrial instrumentation
Create a measurement foundation the plant can trust.
Reliable decisions need suitable instruments, correct placement, and data at the right interval. We support temporary investigations and longer-term monitoring requirements.
Discuss instrumentationHow we do it
We help define the measurement objective, select appropriate flow, pressure, temperature, power, dew point, or related instrumentation, and support installation, logging, and interpretation. Equipment hire and technical supply can be included where suitable.
- Measurement strategy and instrument selection
- Temporary logging or permanent monitoring support
- Installation-point and data-quality guidance
- Instrument hire, technical supply, and commissioning support
A fit-for-purpose measurement plan, equipment recommendation, and usable logged data.
Ancillary equipment support
Match treatment and drainage equipment to the real duty.
Filters, condensate drains, and dryers affect pressure, air quality, reliability, and lifecycle cost. Selection should follow the application and measured operating requirement.

Questions before site work
Frequently asked questions.
Can several services be combined in one assessment?
Yes. Leak detection, flow, power, pressure, and air quality measurements can be combined when a plant needs a system-level view. The scope is built around the questions that must be answered.
Will the assessment interrupt production?
Most measurements are planned around normal operating conditions. Any isolation, installation, or access requirement is agreed with the site before work begins.
How long should measurements run?
It depends on the operating cycle. A stable point test may be short, while demand or pressure profiling should cover representative shifts, production states, and shutdown periods.
Can Fisher verify repairs or improvements?
Verification can be included in the agreed scope. It confirms completed actions and helps distinguish an estimated opportunity from a realised result.
