Industrial Air Compressor Installation and Servicing Across Scotland
Compressed air is widely regarded as the fourth utility in industrial environments. When industrial air compressor systems are unstable or inefficient, productivity and operating costs are directly affected.
Selecting the correct air compressor system is critical, not only for reliability, but for energy efficiency, compliance and long-term cost control.
Our specialist Compressed Air division provides industrial air compressor installation, servicing and maintenance across Scotland. We support manufacturing and process facilities with engineered systems designed around demand profile, operating pressures and future growth plans to ensure stable, efficient and compliant operation.
High Pressure Compressors
High-Pressure Air Compressor Systems for Demanding Industrial Applications
High-pressure air compressors deliver compressed air at pressures significantly above standard industrial air compressor systems, typically from 10 bar up to 400 bar, depending on application requirements.
These systems are specified where precise pressure control, process stability and safe operation are critical, including manufacturing, testing, specialist processing and energy applications.
Our specialist Compressed Air division provides high-pressure air compressor installation and servicing across Scotland, supporting facilities with system specification, safe integration and ongoing maintenance to ensure long-term reliability and regulatory compliance.
Oil Free Compressors
ISO-Compliant Oil-Free Air Compressor Systems
Oil-free air compressors are specified in industrial applications where compressed air purity is critical and even minimal oil carryover is unacceptable. These systems are designed to meet ISO 8573-1:2010 air purity standards and are commonly used in food manufacturing, beverage production, pharmaceutical, electronics and other regulated environments where product integrity and process reliability are essential.
Our specialist Compressed Air division provides oil-free air compressor installation and servicing across Scotland, supporting facilities with correct system specification, certified air quality validation and ongoing maintenance to ensure stable, compliant and reliable operation.
Oil Injected Compressors
Oil-Injected Air Compressor Systems Optimised for Industrial Performance
Oil-injected air compressors are widely used in industrial environments where a reliable, continuous compressed air supply is essential. These systems use oil within the compression process for lubrication, sealing and cooling, delivering stable performance across a broad range of manufacturing and engineering applications.
Our Compressed Air division provides oil-injected air compressor installation and servicing across Scotland, supporting manufacturing facilities with engineered systems designed for durability, efficiency and long-term reliability.
We work with carefully selected manufacturers whose equipment is proven for industrial performance and whole-life cost control. Each system is specified around your site’s operating profile, with energy performance, maintenance planning and return on investment assessed at design stage to ensure measurable long-term value.

Frequently Asked Questions
Here you’ll find answers to common questions about industrial air compressors — including system types such as oil-injected, oil-free and high-pressure options, as well as installation, servicing and support.
A high-pressure air compressor typically operates at pressures above standard industrial levels (usually above 10 bar). Many high-pressure systems operate between 30 and 400 bar, depending on the application, such as PET bottle blowing, testing, or specialist industrial processes.
High-pressure compressors are used where applications demand elevated air pressure for process performance or safety reasons. Common examples include:
- PET bottle production
- Pressure testing
- Gas boosting
- Specialist manufacturing applications
Correct specification is essential to ensure both safety and energy efficiency.
High-pressure systems consume more energy than standard compressors due to increased compression stages and cooling requirements. However, correct sizing, control strategy and system integration can significantly influence operating cost.
Energy efficiency should be assessed at the design stage to avoid unnecessary lifecycle expense.
Oil-injected compressors use oil within the compression chamber for lubrication and cooling, with downstream filtration removing residual oil. Oil-free compressors operate without oil in the compression process, eliminating the risk of oil contamination at source and supporting certified air purity requirements.
Oil-free compressors often involve higher capital investment. However, where air purity is critical, they can reduce risk, minimise downstream filtration requirements and protect product integrity, factors that must be considered alongside operating cost.
ISO 8573-1:2010 defines compressed air purity classes for oil, water and particulates. Class 0 represents the strictest oil contamination limits. Selecting the correct ISO class ensures compliance with process and regulatory requirements.
Modern oil-injected rotary screw compressors are designed for efficient continuous operation. Correct sizing and ongoing maintenance play a significant role in overall energy performance and lifetime operating cost.
Oil separation systems within the compressor remove most of the oil during compression.
Industrial air compressors require routine servicing to maintain performance, reliability and energy efficiency. Maintenance typically includes filter changes, oil checks (where applicable), condensate management, leak detection and system performance monitoring.
Service intervals depend on usage, operating hours and environment, which is why planned maintenance agreements are often recommended.
Yes. CPA Engineered Solutions provides industrial air compressor installation, servicing and ongoing support across Scotland.
Our engineers are trained to support complete compressed air systems, ensuring correct installation, regulatory compliance and long-term reliability.
Oil-injected air compressors use oil within the compression process for lubrication, sealing and cooling, making them suitable for many general industrial applications.
Oil-free air compressors are designed to deliver compressed air without oil contamination and are typically specified where air purity is critical, such as food production, pharmaceutical or electronics environments.
Selection depends on required air quality standards and application risk.

Compressed air is one of the most energy-intensive utilities in industrial environments. Several practical measures can significantly reduce operating costs:
- Reduce system pressure where possible – Lowering system pressure can reduce energy consumption by approximately 3% for every 0.5bar
- Conduct an air leak survey – Many industrial sites lose a significant proportion of compressed air through leaks. In some cases, leak rectification can reduce energy consumption by 15% or more, depending on system condition.
- Optimise compressor control systems
Modern control systems can manage multiple compressors efficiently, reducing unloaded running and improving overall energy performance.
