There are a variety of different configurations of rotary air compressor and there are various reasons for choosing the one for your compressed air application:

• Base Mounted Rotary Screw Compressors
• Tank Mounted Rotary Screw Compressors
• Total Air Systems

When replacing a new compressor you want to consider your current air flow or CFM, system pressure or PSI, voltage and space or location of the equipment.

Efficiency of Screw Compressor - These screw air compressors are very efficient when sized properly. Talk to one of our compressed air experts about how to size a rotary screw air compressor for your system and which control system would be best for your compressed air application:

• Load/No Load Controls are typically standard on all types of rotary screw air compressors. We generally recommend 4 gallons of storage per every 1 cfm and at a minimum 2 gallons of storage per every 1 cfm of output.
• Modulation Controls are typically installed on compressors where a continuous flow of air is required. Modulation can be very inefficient when applied to applications where the air demand is variable. For example, the BHP would be 89% when using modulation controls on a rotary screw air compressor where the air demand is 50%.
• Variable Speed Drive Controls, VFD type controls are very efficient when sized correctly and very inefficient when misapplied. Contact one of our sales staff to explore this option.

Don't Forget These Important Pieces of Your Air System

Air Dryers help reduce or eliminate any moisture from entering your process.

Air Tanks are one of the most important pieces of compressed air systems; they help reduce energy and maintenance costs.

Air Filters, help reduce the amount of particulate and oil from entering your process.
