What are the types of oil free air compressors

Oil free air compressors are becoming increasingly popular in many industries because they offer many advantages over traditional oil-lubricated air compressors. Oil free air compressors are more environmentally friendly, more efficient, and less maintenance, making them ideal for many applications. There are several types of oil free air compressors on the market, each with their own unique advantages and disadvantages. In this article, we will explore the most common types of oil free air compressors.

Scroll Air Compressor

A scroll compressor is a type of oil free air compressor that uses a rotating spiral vortex to compress air. One vortex is stationary and the other moves in a circular motion, compressing the air as it moves towards the center. Scroll air compressors are ideal for applications that require low noise levels and are commonly used in medical and dental environments, laboratories, and other industries that require clean air.

One of the main advantages of scroll air compressors is that they require very little maintenance compared to other types of air compressors. They can also operate at lower temperatures, making them more energy efficient than other oil free air compressors.

Diaphragm Air Compressors

Diaphragm air compressors use a flexible diaphragm to compress air. The diaphragm moves up and down, creating a vacuum on one side and compressing air on the other. These compressors are typically used in applications that require high purity air, such as food processing, pharmaceuticals, and electronics manufacturing.

A major advantage of diaphragm air compressors is that they produce oil free, contaminant-free air that is ideal for sensitive applications. They are also relatively quiet and require minimal maintenance.

Rotary Screw Air Compressors

Rotary screw air compressors use two interlocking helical screws to compress air. The screws rotate in opposite directions to compress the air between them. These air compressors are typically used in large industrial applications such as manufacturing, construction, and mining.

One of the main advantages of rotary screw air compressors is their efficiency. They can deliver large volumes of compressed air at a relatively low cost. They are also durable and require very little maintenance.

Centrifugal Air Compressors

Centrifugal air compressors use a high-speed impeller to compress air. The impeller rotates at high speeds, creating centrifugal force in the compressed air. These air compressors are typically used in large industrial applications such as power generation, chemical processing, and oil and gas production.

One of the main advantages of centrifugal air compressors is their ability to deliver large volumes of compressed air at high pressures. They are also energy efficient, with some models having efficiencies of up to 90%.

Reciprocating Air Compressors

Reciprocating air compressors use a piston and cylinder to compress air. The piston moves back and forth to compress the air in the cylinder. These air compressors are typically used in applications that require high pressure air, such as automotive repair and maintenance, painting and sandblasting.

One of the main advantages of reciprocating air compressors is their ability to deliver high pressure air. They are also relatively compact and portable, making them ideal for mobile applications. However, they are typically noisier and require more maintenance than other types of oil free air compressors.

There are several types of oil free air compressors available, each with their own unique pros and cons. When choosing an oil free air compressor, it is important to consider the specific requirements of the application, such as air purity, volume, pressure, and noise level, to ensure that you choose the right air compressor for your needs.
