Oil Free Compressor

Elgi introduces its unique range of oil free air-cooled compressors for industries that demand oil-free air at their application point. The non-lubricated and two-stage air-cooled compressors benefit customers by ensuring low running costs and low energy consumption. The air-cooled design provides additional value to customers by eliminating the need for exhaustive water cooling systems, thereby saving industrial water costs.

A typical Elgi package consists of motor, compressor, air-cooled cooler, a SOUL air receiver with associated piping, and control panel. Elgi also offers a complete range of downstream accessories such as refrigerant/ desiccant dryer, vertical air receiver, oil moisture separator, filters etc. according to the air quality demand.

The Design Advantage:

Reduced transmission losses
Direct drive

• Unlike belt drive, the direct drive through a coupling increases the efficiency of the compressor by reducing transmission losses . This mechanism is inherently maintenance-free when compared to traditional belt drive designs.

Effective heat transfer
Piston and piston rings

• Pistons are made of cast iron (LP) and aluminium (HP) for effective heat transfer from compression chambers.

Reduced wear
Robust single piece crankshaft

• Extremely robust single piece crankshaft helps to minimize free inertia forces and moments, leading to reduced wear & tear and increased durability. Dynamically balanced crankshaft increases the endurance limit for long runs.

Longer working life
Split type connecting rods

• The split type connecting rods are made of while metal sleeves In this type of design the sleeves are only required lobe replaced atspecified intervals.
