A frequent question (and rightfully so) for compressed air products is “How much compressed air does it use?” Fortunately for EXAIR, we can provide these values with confidence, knowing the research and development, testing, and quality control that goes into the products we make.
For many applications, this question is cut and dry. For others, particularly those that do not currently have compressed air on site, the question leads to further conversation. One of the questions that is often asked, is “What type of compressor should we use with these products?”
While the end-use products (EXAIR products) will operate regardless of the compressor type, there are benefits and advantages to various compressor types in different applications.
For short-term or intermittent use, a reciprocating compressor can be an excellent choice. The size and weight, maintenance requirement (relatively low), and ease of procurement make them very suitable for small demand applications. They are also suitable for high pressures. Keep in mind that reciprocating compressors typically have higher noise levels and higher cost of compression when compared to screw compressors.
When the compressed air need is high volume, and the demand requires a continuous supply of compressed air, a rotary screw compressor can be a better choice. Rotary screw compressors are designed for more regular use in industrial applications, are (generally) more maintenance intensive, feature partial load capability allowing to align supply and demand, and can be found in a variety of sizes. You can expect to pay more for these models than the reciprocating compressors.
From an engineering standpoint, reciprocating compressors are dynamic devices, and screw compressors are positive displacement devices. Click here for a more in depth look at screw compressor operation.
EXAIR manufactures many, many compressed air driven devices with a concentration on solving problems, conserving compressed air and making it safe by meeting OSHA standards. And, although we do not supply or support any specific compressor manufacturer, our Application Engineers are well versed in compressed air generation and suited to discuss those needs with our customers.
