More Air. Same Relentless Reliability. Built for Real Production.
When your operation starts demanding more air, the last thing you want is a compressor that struggles to keep up.
The ELGi EG 15 20 HP Rotary Screw Air Compressor is built to handle higher air demand, longer run times, and tougher environments—without sacrificing efficiency or reliability. This is a true industrial workhorse, engineered to run day after day in conditions that would wear down lesser machines.
With configurable pressure options from 100 to 175 PSI, the EG 15 adapts to your system while delivering the consistent performance your operation depends on.
⚙️ Performance by Pressure (Built Around Your Demand)
- 100 PSI → 94 CFM
