Browse Scroll Compressors
Our scroll compressors deliver smooth, pulsation-free compressed air for demanding environments where quiet operation, energy efficiency, and consistent performance matter.
Designed to be compact, robust, and easy to maintain, they’re widely used across manufacturing, healthcare, food and beverage, and other industries that require continuous operation within sensitive applications.
At Diamond Compressors, we stock a wide range of scroll compressors to suit different airflow needs, pressures, duty cycles, and air-quality requirements. We also offer oil-free models for applications where contaminant-free compressed air is a necessity.

About Scroll Compressors
A scroll air compressor uses two interlocking spiral elements to compress air smoothly and continuously. One scroll stays fixed, while the other orbits in a controlled motion. As it moves towards the centre, it reduces the volume of trapped air and increases its pressure.
Because scroll compressors don’t use pistons or oil-lubricated chambers, they can deliver oil-free compressed air. With fewer moving parts and less friction, they typically run more efficiently and offer strong long-term reliability.
This makes them well suited to clean-air applications and settings where low noise matters. They’re also commonly used in refrigeration, air conditioning, and heat pumps, where they compress refrigerant rather than air.
The right scroll compressor depends on the airflow and pressure you need, the duty cycle, required air quality, your electrical supply, and the space available for installation. If you’re replacing an existing unit, check the make, model, and reference number to ensure a like-for-like match.

Scroll Compressor FAQs
A scroll compressor is a positive-displacement compressor that uses two interlocking spiral parts to compress air. One spiral stays still while the other orbits around it, steadily reducing the air space and raising pressure. This smooth, continuous action delivers consistent compressed air with very low vibration.
A scroll compressor is also commonly referred to as a spiral compressor. This name refers to the spiral-shaped scrolls that are used to compress air.
Léon Creux invented the scroll compressor and secured the first patents in 1905 in both France and the United States.
Air enters through the outside of the scrolls and becomes trapped in the compressor chambers. As the orbiting scroll moves, the chambers become progressively smaller, compressing the air and directing it towards the centre of the scrolls, and exits through a discharge outlet. This design allows continuous compression with fewer moving parts compared to piston-based systems.
Scroll compressors deliver clean compressed air for a wide range of commercial and industrial uses, including:
- Healthcare
- Dental clinics
- Laboratories
- Pharmaceutical manufacturing
- Food and beverage production
- Electronics manufacturing
- Cleanrooms
- Precision engineering
Depending on the model and application, scroll compressors can offer:
- Quiet operation with low vibration
- Fewer moving parts
- Reliable, continuous air supply
- High energy efficiency
- Compact design
- Oil-free air for clean applications
- Lower maintenance needs than many other compressor types
A multi-scroll compressor houses two or more scroll elements in one unit. This increases air output and adds built-in resilience. If one module needs maintenance, the others can continue running.
Scroll compressors compress air using two interlocking spiral scrolls. Reciprocating compressors use pistons moving within cylinders.
Scroll compressors typically have fewer moving parts and produce less noise and vibration.
Reciprocating compressors can be a better fit where different pressures, capacities, or duty cycles are required. The right choice depends on your application and performance needs.
Neither is “better” in every situation. Rotary and scroll compressors use different compression methods, which affect load, noise, and vibration.
Scroll compressors typically run with a lower mechanical load than rotary compressors, which can reduce noise and vibration.
Lower vibration can also make scroll units a good choice where a smoother-running compressor is important.
The best option depends on the airflow, pressure, duty cycle, and air quality your application requires.
