Air compressors essentially convert power from motors or engines into energy. Using the basic principles of atmospheric pressure, power is required to compress air and energy is then released as that air expands to return to normal. By pressurising air and storing it, compressors can provide potential power for a number of important uses such as powering construction tools like nail guns, wrenches, drills and saws, turning air turbines, filling tires and running certain heating, ventilation and air conditioning (HVAC) systems. Air compressors are generally considered to have many advantages over electrical and hydraulic power, including simpler design, fewer parts, higher safety characteristics and lower equipment weight.
Compressors are normally based on one of two principles, positive or negative displacement. Positive-displacement refers to forcing air into a space with a decreased volume using either pistons, rotary screws or vanes. Negative-displacement refers to the use of centrifugal compressors for compression and is more common in larger scale industrial uses. Gas and diesel compressors are the most common type of air compressor and are popular in areas with less reliable electricity, while electric powered compressors are used in areas with guaranteed access to power, such as workshops, plants and production lines.
As a critical component of many construction processes, production lines and large scale industrial operations, compressor support is an essential consideration in keeping air compressors running efficiently and consistently. In normal operation, oil levels need to be checked routinely, air filters should be cleaned, power supplies need to be set up properly (if electrically powered), the desired air pressure needs to be set and certain steps need to be taken once finished with individual tasks (such as draining the tank to avoid moisture build-up). Properly maintaining an air compressor can lead to energy reductions over 10% if done correctly by both users and support providers.
The potential for cost savings, safety and efficiency makes obtaining professional support a smart move to keep an air compressor running at optimal performance over time. Most optimisation exercises require specialised expertise and as such, external air compressor support providers are normally recommended. Services offered by various providers can be integrated and comprehensive or more individual and specialised. Service levels can include walk-through evaluations, full system assessments or full system audits. Service providers can also provide emergency services, replace worn-out or missing parts and provide urgent replacement or rental options.
A final consideration for external support is industry standards and guidelines as well as legal requirements. The British Compressed Air Society is a trade association for manufacturers, sellers and users of air compression products and maintains professional standards across the industry. UK and European legislation also exists to regulate in terms of worker health and safety, workplace noise and environmental protection. While performing in-house maintenance is extremely important to continue reliable and efficient operations, obtaining professional compressor support can not only assist a company in optimising operations and overall productivity but also adhering to the numerous laws, regulations and standards that govern the industry.
