Air Compressors: Different Types And What They Are Used For

Air compressors are commonly used in industries such as manufacturing, construction, agriculture etc. Air compressors come in many different variations and each type has a different purpose. It is vital that in environments where compressors are operated, health and safety regulations must be followed, and equipment must be always working to the best of its ability with no faults. It is important to book a compressor service to ensure the equipment is showing no signs of malfunctions or failures.

Oil-Injected Compressors

Oil-injected screw compressors use oil to increase the pressure and volume of air. These types of compressors are used in gas turbines to generate compressed air. They have a high compensation ratio and can handle gas pressure fluctuations from pipelines.

Rotary-Lobe Compressors

Rotor-lobe compressors use a reciprocating motion to move gas from one section of the rotor to the next. As the pressure increases in the discharge chamber, the discharge gas is removed physically from the suction chamber. The space between the inlet and discharge plenums and the compression chambers is characterised by a mechanical barrier which is provided by spring-loaded check valves.

Oil-Free Compressors

Oil-free compressors are an excellent choice if you need an air compressor that will provide a high volume of air without using oil. These types of compressors have dual pumps and can achieve the desired CFM/PSI at half the RPM of their oiled counterparts. They also feature heat-dissipating aluminium cylinders. Oil-free compressors can be advantageous for many applications, especially in cold climates, because they do not need oil to operate.

Digital Compressors

Compression is the process of lowering the sound level to achieve a specific sound level. Digital compressors utilise a variety of mechanisms to achieve this goal. Some of these mechanisms include VCA (voltage-controlled amplifier) and LP (passive loop) circuits. The VCA compressor is the most common type of compressor, and it is found in most musical applications. The VCA mechanism gets its name from the fact that it employs a control signal to regulate the level of the input signal.

Variable Speed Drive Compressors

Variable speed drive compressors are a great option for industrial applications. They are energy efficient and can save businesses significant amounts of money. Depending on the system and demands, a VSD can save 30 percent to 50 percent on energy.

Piston Compressors

Piston compressors are designed to provide high air pressure. They are available in different designs, from stationary units to mobile units. A mobile piston compressor is more versatile and can be used in different situations.

Final Words

Air compressors are versatile pieces of equipment that can be used in many industries. Before you rent or buy your air compressor be sure to have carried out research on which type you are going to require to ensure it can fulfil the service. Be sure to carry out compressor services regularly to avoid malfunctions.
