Collection: Oil Free Scroll Compressors

How Does an Oil-Free Scroll Compressor Work?

An oil-free scroll compressor uses two interleaved spiral-shaped scroll elements to compress air. One scroll moves in an orbiting motion while the other remains stationary, reducing the volume of trapped air and increasing its pressure.

Unlike oil-injected compressors, oil-free scroll technology does not introduce lubricating oil into the compression chamber.

Industrial Applications of Oil-Free Scroll Compressors

Oil-free compressed-air technology may be considered for applications including:

●        Food and beverage processing

●        Pharmaceutical manufacturing

●        Medical and dental facilities

●        Laboratories

●        Electronics production

●        Packaging operations

●        Paint and coating processes

Each application has different compressed-air quality requirements. Confirm that the selected compressor and air-treatment configuration meet the intended process requirements.

Explore Oil-Free Scroll Compressor Options

MasterAire offers oil-free scroll air compressors across multiple horsepower configurations, including 5 HP, 10 HP, 15 HP, 20 HP, 30 HP, 40 HP, 50 HP, and 75 HP options.

Available configurations range from 5 HP to 75 HP, allowing facilities to compare delivered airflow and electrical requirements across different capacity levels.

A higher horsepower rating does not automatically indicate a better choice. Required airflow, operating pressure, and duty cycle should guide compressor selection.

Choosing the Right Industrial Oil-Free Air Compressor

Before selecting an industrial oil-free scroll compressor, evaluate:

●        Required airflow in CFM

●        Operating pressure in PSI

●        Compressor horsepower

●        Duty cycle and operating schedule

●        Voltage and phase requirements

●        Compressed-air quality requirements

●        Available installation space

●        Operating environment

●        Maintenance requirements

●        Downstream air treatment

●        Future compressed-air demand

Horsepower alone should not determine compressor selection. Compare published compressor specifications with actual equipment requirements.

Oil-Free Scroll vs. Oil-Injected Compressors

The primary difference is the compression process. Oil-free scroll compressors do not inject oil into the compression chamber, while oil-injected compressors use oil for lubrication, sealing, and cooling.

Both technologies require appropriate system design and maintenance.

Frequently Asked Questions About Oil-Free Scroll Compressors

What is an oil-free scroll air compressor?

An oil-free scroll air compressor uses interleaved spiral-shaped scroll elements to compress air without injecting oil into the compression chamber. It is commonly considered for applications where controlling oil contamination is important.

How does an oil-free scroll compressor work?

An oil-free scroll compressor uses an orbiting scroll and a stationary scroll to trap and compress air. As the air moves through progressively smaller chambers, its pressure increases.

Where are oil-free scroll compressors used?

Oil-free scroll compressors may be considered for food processing, pharmaceutical manufacturing, medical and dental facilities, laboratories, electronics, packaging, and other applications with specific compressed-air quality requirements.

How do I choose the right oil-free scroll compressor?

Determine the required airflow in CFM and operating pressure in PSI. Then evaluate horsepower, duty cycle, electrical supply, installation conditions, air-quality requirements, maintenance, and future demand.

Do oil-free scroll compressors require air dryers?

Air dryers may still be necessary because oil-free compression does not eliminate moisture from compressed air. The appropriate drying and filtration equipment depends on the required pressure dew point and application.
