Industrial Air Compressor Buying Guide

Industrial air compressor systems range from small, portable units to large-scale industrial machines capable of driving entire manufacturing facilities. Making a smart purchasing decision requires educating yourself about the basics of how a compressor works, what models are available, and to which application they are best-suited.

There are two main types of air compressor systems:

  • Rotary screw: Rotary screw machines are a type of positive displacement compressor that features a pair of matched helical screws. These screws drive air into a special chamber while at the same time shrinking the size of that chamber, forcing the air to compress.
  • Reciprocating/piston: Reciprocating compressors are another type of positive displacement machine. Unlike rotary screw compressors, they compress air by using a series of one-way valves to introduce it into a chamber, where the constant motion of a series of pistons compresses it.

After you’ve determined which type of compressor is best for your application, you’ll need to decide which model is best. Comparing various models and manufacturers requires knowing what to look for. Here are some key factors to consider when making a decision:

  • Power: Delivering enough compressed air to drive your tools, machines, and processes is the key goal of any industrial compressor. Make sure you choose a machine that has the power necessary to get the job done.
  • Efficiency: More power requires more fuel, and fuel is an ongoing operating expense for any business. Keep costs — and your carbon footprint — low by choosing an energy-efficient machine.
  • Maintenance requirements: Any time a compressor is down for service is a time your team can’t maintain optimal productivity. A good air compressor system will require as little maintenance as possible, so you can keep your crew working and production lines running.
  • Warranty: Any good air compressor manufacturer will stand behind their products. ELGi compressors feature one of the best warranties in the business, with extended coverage available in select models for up to 10 years, covering the heart of the unit, the air end.
