What is a Compressor?

A compressor is a device that increases the pressure of a gas (like air) by reducing the volume. Often, compressors are run by electric motors. The motor is controlled by a compressor drive.

There are many kinds of compressor:

  • Positive displacement compressor

  • Reciprocating compressor

  • Iconic liquid piston compressor

  • Rotary screw compressor

  • Rotary vane compressor

  • Rolling piston

  • Scroll compressor

  • Diaphragm compressor

  • Air bubble compressor

  • Centrifugal compressor

  • Diagonal compressor

  • Axial compressor


Gas compressors are used in a wider range of industrial and commercial settings:

  • Pipelines

  • Petroleum refineries

  • Gas processing plants

  • Chemical plants

  • Refrigeration systems

  • Welding

  • Pneumatic tools

  • Plastic manufacture

  • Internal combustion engines

  • Aircraft

  • Jet engines

  • Diving equipment

  • Submarines

  • Air turbines
  • Rail vehicles

  • Tires

  • Fire pistons

Variable Frequency Drives

The drive supplying the motor is often a variable frequency drive or VFD. Drives are becoming increasingly advanced.

As drives become more complex, manufacturers are simplifying how they install them and how clients can use them easily. This makes VFDs more accessible in a wider range of industrial settings.

There is now no need for complicated settings and adjustments, and commissioning can be performed by a mechanic who has no specialist electrical knowledge. It is simple to set up the application that controls the VFD with user-friendly software tools and databases that contain information already loaded on a variety of motors, compressors, and other components.

VFDs can save a company money, so the drive will pay for itself after eight months. This saving is due to the energy-conserving features of the drive. Therefore, there is no financial risk in installing one of these drives.

VFDs are much improved and have many benefits when they are used to power compressors. Add to that the money-saving aspects and you can see that VFDs are a welcome addition to a compressor application.

Variable Speed Drives

A variable-speed drive or VSD air compressor is an air compressor that uses variable-speed drive technology. This kind of compressor uses a unique drive to control the speed (RPM) of the machine, which saves energy when compared to a fixed speed version. This variable speed drive improves the efficiency of the compressor.

The most common kind of VSD technology in the air compressor world is a variable-frequency drive, which changes the incoming AC power to DC and then back to AC power using an inverter switching circuit.

The benefits of variable speed drives include reducing power expense, lessening power surges (from starting AC motors), and giving a more constant pressure.

Typically 20% of any factory’s electricity bill is caused by the production of compressed air. Most modern factories are trying to cut costs, and energy awareness is an important area of concern. Much energy used to produce power is wasted.

Enormous savings can be gained by installing a variable speed drive compressor instead of an existing rotary screw or piston machine. As a result of these savings, many governments across the world are encouraging manufacturers to change to VSD technology to reduce wasted energy. Governments may offer many incentives to the industry like tax rebates or interest free-loans, to cover the cost of installation.

In addition to energy-saving costs, a variable speed drive will save on repair and maintenance bills. It will also prove cheaper to operate on a daily basis. The drive ensures maximum energy efficiency throughout the whole system. Precise control reduces wear on the compressor. Therefore, the lifecycle of the components is prolonged and there can be a greater interval between servicing events.
