7 JULY 2021 WorldWide Drilling Resource ® Choosing the Right Air Compressor Adapted from Information by Chuck Hamilton Director of Marketing, BOSS Industries Many times, choosing the right method of air compression is just as important as choosing the correct capacity and pressures (PSI). Think about it like this - do you need continuous air, for jack hammers, piercing tools, or running air tools for longer than 20 minutes at a time? Or, do you need intermittent air for impact wrenches, drills, or any air tool used for a short duration of time? For those in need of continuous air, the best choice would be a rotary screw-type compressor, while those needing inter- mittent air would be better off using a piston-type compressor. What's the difference? A rotary screw compressor is air-on-demand, meaning you have immedi- ate, continuous air capable of running for hours or even days. The bonus is there is no air reservoir (tank) needed. This design utilizes two rotating lobes (screws) in an oil flooded system. The oil serves three primary functions - one, it seals the tolerances between the lobes to create compression; two, it helps lubricate the bearings on the rotors; and three, it transfers heat from compres- sion to the cooler. A piston-type compressor (reciprocating compressor) uses the piston and rings to build pressure and fills an air reservoir (tank). This requires a short pressure build time to fill the appropriate size air reservoir and is ideal for on/off, short air usage applications. What's next? You need to define what CFM (cubic feet per minute) is needed by exam- ining the tools that will be used on the job. We recommend sizing your com- pressor to the rated specifications for the tools being used to ensure the life span and investment in your air tools. Choosing the right size and type of air compressor is just as important as choosing the right tool for the job. The BOSS ® Bullet D rotary screw air compressor offers a remote start/stop feature. C&G
