When to Use a Reciprocating Air Compressor
Reciprocating air compressors are best for applications that require intermittent air such as machine shops, construction sites, and small-scale manufacturing.
Another consideration is the future growth of a business. It may be advantageous to purchase a larger compressor ( up to 50% larger) that can scale with the business. Another advantage of a larger compressor is proper cycling which reduces heat and wear and tear on the motor.
When to Use a Rotary Air Compressor
Rotary air compressors are best for applications that require consistent air such as large-scale manufacturing and conveyor systems. They are designed to operate nonstop and produce a strong and consistent flow of air. Because the air produced by rotary air compressors is much cleaner than air produced by reciprocating compressors, they are the best choice for paint lines, food processing and packaging, and other applications where clean, dry air is essential.
Fixed speed rotary screw compressors are not designed for intermittent use and may experience performance issues if they are not used close to their full capacity. If your compressed air demand varies, but you want the advantages of a rotary screw machine, you may want to consider a variable speed drive (VSD) compressor. While a fixed-speed compressor is always operating at the same RPM, a VSD motor can ramp up or down depending on demand.
