J Ll Leach is supporting the aviation sector and wider aerospace industry with reliable Atlas Copco air compressors, supplied and installed from our Stoke, Birmingham and Shrewsbury branches.
Without reliable compressed air, production shuts down, quality plummets, and audits fail. Air compressors play a pivotal role in ensuring safe operation and optimal performance across the supply chain, from Tier 1 manufacturers to defence contractors.
Every critical process has an air purity requirement that must be met by an appropriately certified level of air cleanliness. Failure to provide the correct quality of air at each process step will result in component failures, expensive rework, and non-conformance during audits.
For example, sensitive electronics in avionics can be damaged by even trace amounts of oil vapor. The international standard used to certify the purity of air is ISO 8573-1:2010, which categorises air by its concentration of particles, water, and oil.
| Application | Recommended ISO 8573-1:2010 Class |
|---|---|
| Paint & Coating | [1:2:1] |
| Composites / Autoclave | [1:2:1] or [1:1:1] |
| General Pneumatic Tools | [2:4:2] / [3:4:3] |
| Avionics Cooling & Testing | [1:2:1] |
| Additive Manufacturing | [1:1:1] or Class 0 |
| Breathing Air | Must meet BS EN 12021 |
Our range of air compressors offer the maximum reliability required for the aviation industry.

Key benefits of our Atlas Copco solutions include:
The primary risk in aerospace applications is oil contamination. The solution is to remove oil from the equation entirely. Our range of oil vs. oil-free air compressors explains the technology in detail. Atlas Copco’s Z-Series compressors are certified ISO 8573-1 Class 0, guaranteeing zero risk of oil entering your processes.
With Variable Speed Drive (VSD⁺) technology, air compressors for aerospace can reduce energy consumption by up to 35%. Furthermore, up to 94% of the electrical energy can be recovered as usable heat.
Achieving specific purity classes requires advanced air treatment. We supply integrated refrigerant and desiccant dryers capable of achieving pressure dew points as low as -40°C. This is combined with multi-stage filtration to remove all forms of contamination. Understanding the Importance of compressed air quality and filters is the first step toward achieving guaranteed purity.
Eliminate the logistics and safety hazards of high-pressure cylinders. We install on-site nitrogen generators using PSA or membrane technology, providing a continuous, on-demand supply of gas for safety-critical applications, such as fuel tank inerting, aircraft tire inflation, charging oleo-struts, and inflating escape slides.
In the aerospace sector, compliance is not optional. Air compressors are used within strict regulatory frameworks. A compressed air system is an auditable input for quality standards, such as AS9100, and for noteworthy process accreditations from NADCAP. Our compliance services ensure you:
These measures don’t just protect quality, they reduce Scope 1 & 2 emissions and support SBTi-aligned Net Zero pathways for UK aircraft manufacturing.
Auditors require objective, traceable evidence that your air supply consistently meets the required specification. Atlas Copco’s SMARTLINK system provides real-time data logs, while our certified testing provides the documented evidence you need.
For any system with a pressure vessel larger than 250 bar-litres, we act as the Competent Person to create and manage your Written Scheme of Examination as required by PSSR 2000. For a comprehensive overview of regulations, refer to our UK Compressed Air Compliance Guide.
A robust compressed air system anticipates and mitigates potential failures. Our system design process addresses common risks head-on.
Selecting the appropriate equipment is only half the battle. J Ll Leach has the complete expertise necessary to ensure performance and compliance for the UK’s aerospace elite.
