Factors to consider when selecting a rotary screw compressor

Rotary screw air compressors are popular for operations in many industries. They can provide massive airflow while running quietly and being energy-efficient. Compressors are built to last and are easy to maintain. Rotary compressors are ideal for industries that require a high and continuous airflow. Manufacturing, food processing, pharmaceuticals, paint lines, packaging. The list of the use cases is endless. But before selecting a rotary screw air compressor for your business, it is important to consider some important factors that will impact your operation, your basic need, your cost, and your overall business. Let us review some of the major factors that one should consider before selecting a rotary air compressor.

Energy Efficiency and Cost Considerations

Energy efficiency and cost considerations are crucial for businesses that rely on rotary screw air compressors. The rotary screw-type air compressors that are more efficient and cost-effective can lead to significant savings on utility bills. The total cost of ownership includes not only the purchase price but also installation, maintenance, and energy costs. Choosing an energy-efficient compressor can help reduce these costs.

Selecting a compressor that is the right size for your needs is another way of saving money. Variable frequency drives (VFDs) can help match the airflow to your specific demands, reducing energy wastage and improving efficiency.

Small businesses like automotive repair shops, painting, and woodworking shops, but also large manufacturing plants rely heavily on compressed air. By considering energy efficiency and cost factors, these businesses can make informed decisions about which rotary screw air compressor is best suited to their needs, ultimately saving money and improving productivity.

Noise Level and Environmental Impact

There are use cases where noise level and environmental impact specifically matter. Food and Beverage manufacturing and pharmaceutical manufacturing especially have a very low tolerance for noise levels. By prioritising features such as low noise levels, anti-vibration technology, and silent power technology, ELGi can offer a quieter and more environmentally friendly compressed air system to its customers.

ELGi's EN Series screw air compressors are known for their low noise levels, offering one of the lowest sound levels in the industry at as low as 61 dBA.

Maintenance and Serviceability

Maintenance and service requirements for rotary screw air compressors are essential for ensuring good performance and longevity. Choosing a high-maintenance compressor can impact your business negatively. Frequent shutdowns can increase downtime and higher operating costs. Rotary screw air compressors, while relatively simple in design, require periodic maintenance to ensure continued performance.

In addition to increased cost, an inferior compressor may have a greater environmental impact due to increased energy consumption and the potential for more frequent replacement of components which generates more industrial waste.

Compressed Air Quality and Industry Standards

Compressed air quality can be a crucial factor to consider when selecting a rotary screw air compressor. Particularly for businesses that require high-quality compressed air for their equipment and processes.

Contaminations in compressed air can cause defects and lead to impurities in the end product.

The ELGi electric air compressors are known for their best compressed air quality. ELGi's oil-free rotary screw air compressors, such as the AB and OF Series, are designed to produce compressed air that is free from oil contamination, which is necessary for industries like pharmaceuticals, food processing, and electronics manufacturing.

Conclusion

Selecting the right rotary screw compressor can be a daunting task, considering the number of options available in the market. However, by keeping factors, like compressor capacity, energy efficiency, noise level, maintenance need, and build quality, you can choose a rotary screw compressor that will complement your operations and will be a trusted partner for a long time.
