How Does an Oil Free Air Compressor Work?

What is an oil-free air compressor?

An oil-free air compressor, as the name suggests, operates without the use of oil for lubrication. This type of compressor relies on the materials and technologies that reduce friction and heat to ensure smooth operation. In contrast to traditional oil-lubricated compressors, oil-free air compressors deliver a supply of compressed air that is free from oil and contaminants.

Understanding the Working Principle of an Oil-Free Air Compressor

The operation of an oil-free air compressor can be broken down into the following steps:

1. As the compressor starts, the motor begins to rotate the shaft, which is connected to one or more pistons.
2. The downward movement of the piston creates a vacuum in the cylinder, drawing in air through the intake valve.
3. When the piston moves upwards, the air gets compressed and is pushed out through the exhaust valve.
4. The compressed air is then stored in a tank for future use.

Superior Oil-Free Air Compressor Solutions

We offer high-quality, stable, and efficient oil-free air compressor solutions. Our innovative single-screw compression technology ensures stability while maximizing your production efficiency.

Our Professional Certifications

Our air compressors are ISO8573-1 certified, meaning they have an oil content of class 0, particle count of class 0, and moisture content of class 0. We also hold ISO9001 quality management system certification and ISO14001 environmental management system certification.

Advantages of Oil-Free Air Compressors

1. No oil contamination: These are ideal for industries that require high purity compressed air, such as the food, pharmaceutical, and chip manufacturing industries.
2. Avoids oil-gas mixing: This ensures the provision of dry and pure air.
3. Reduces maintenance costs: No need for oil filters, oil-gas separation cores, and compressor replacements, thus reducing maintenance costs.
4. Improves product quality: In industries like painting and pet bottle blowing air compressor, oil contamination can negatively impact the final product quality.
5. No need for post-processing: This reduces maintenance costs for post-processing equipment as no oil filter can completely filter residual oil in the air. Oil-free air compressors avoid this problem.

Our Patented Technology

We utilize patented French technology that incorporates a completely stainless steel two-stage direct drive host. This host has several key features:

1. High efficiency: Thanks to the absence of gas valves and numerous friction parts, energy loss is minimized, thus improving the efficiency of air compression and saving resources.
2. Provides higher pressure: The structural characteristics of the single screw compressor allow it to provide higher pressure compressed air. During the compression process, the engagement of the screws gradually compresses the air, increasing its density. The axial and radial forces on the screws are very small, allowing for higher air outlet pressure.
3. Lower maintenance costs: Compared to other types of compressors, the single screw air compressor has a simple structure, low failure rate, and relatively easy maintenance.

Applications of Oil-Free Air Compressors

Oil-free air compressors have a wide range of applications in various industries including:

1. Food and Beverage Industry: Provides clean compressed air for food processing, packaging, and bottling – ensuring safety and hygiene.
2. Medical and Pharmaceutical Industry: Used for gas transportation, drug manufacturing, laboratory instruments, and surgical equipment.
3. Electronics and Semiconductor Industry: Suitable for chip manufacturing, electronic assembly, and printed circuit boards.
4. Automotive Industry: Provides compressed air for painting, cleaning, grinding, inflating, and operating pneumatic tools.
5. Textile Industry: Compressed air is needed to drive spinning, weaving, and textile machinery.
6. Packaging and Printing Industry: Used for pneumatic transport, coating, coding, and printing equipment.
7. Construction and Building Industry: Such as pneumatic tools, concrete spraying, drilling, and painting on construction sites.
