What type of compressor should I use?

When selecting their air compressor style, there are many factors for compressed air systems operators to take into consideration. For those just exploring this process, it’s important to review the marketplace and to determine which products offer the best value for money over the long-term. Within this post, we’ll explore the various compressors on the marketplace and outline the benefits they offer to operators within their applications.

Vast Majority Now Use Large Rotary Air Compressors

Most companies now employ single-stage lubricant injected rotary screw air compressors, built with an electricity-driven motor. One of the leading benefits this type of compressor provides is that it features a low level of vibration to help reduce maintenance requirements over its lifetime. And because single-stage lubricant injected rotary screw air compressors can operate at broad range of pressure and capacity levels, they’re highly flexible and offer compressed air operators scalability within their processes.

Both Single Stage and Two-Stage Compressors Suitable as Trim Compressors

Many companies favour two-stage compressors as the base-load compressor within their system, and some manufacturers claim their two-stage systems offer greater lifetime performance. Because both two-stage and single-stage processors can be designed with variable speed control, they are ideal as trim compressors and provide high-efficiency operation at reduced loads.

Does the Application Require Intermittent Operation or Continuous?

Air requirements are a critical element in making any decision on the type of compressor used. For example, in any system where the air required is 100 cfm and the air must be supplied continuously throughout the application, then the company may find a rotary screw the best option for the process. However, if the 100 cfm of air needs to only be supplied intermittently, they might consider the use of an air-cooled reciprocating compressor to help minimize air costs and improve system efficiency.

Focus on Lifecycle Costs

A mistake companies make in reviewing the available compressors within the marketplace is only taking into consideration the initial purchase cost of the equipment. This is only one variable within the selection process and is often not as important as the full life-time cost of running and maintaining the system.
A comprehensive understanding of all available compressors is required to make an effective purchase decision. To learn more on compressor technology and how to make the right selection for your plant, speak with our team directly.
