Optimal Capacity Control

• Varion intake valve installed at the compressor inlet
• Optimally controls capacity during start up, operation and shutdown

OSBID

• Enables efficient separation of air and oil with minimal pressure drop

100% Step-less type capacity control system

• Compressor regulates the output based on actual plant requirement
• Reduction in air demand and power consumption

Virtually oil-free compressed air separation system

• 3-stage centrifugal gravity separation system
• Baffles at bottom reduce impact ensuring longer life of the separator element
• Main and bearing oil filters
• Longer life and reliability of the compressor unit

Dual Oil Filters

• High filtration level at all flow levels and temperatures
• Increased life of bearings

Suction Filter - Total dust protection

• Heavy duty cyclopac two stage air filtration system
• 10 microns filtration level
• Increased life of airend

ELGI reciprocating air compressors are designed for optimum efficiency and minimum maintenance.
