Product Description:
The ELGi Two Stage Oil Free Piston Compressors are Elgi's solutions to the increasing need of industries and research institution for higher purity in compressed air applications.
"No oil in the compressor is equal to no oil in output air from the compressor" Elgi oil-free compressors are engineered on this principle. Elgi has adapted a dry crankcase that is totally devoid of oil. The internal moving and friction parts of the compressor have been designed suitably to overcome the absence of lubricating oil. Sealed bearings have been used for the crankshaft and connecting rods. Poly Tetra Fluoro Ethylene (PTFE) coated piston and PTFE rings have been used to provide wear resistance.
Designed for the industrial duty, the compressor is a perfect solution for applications where oil carried in the air can affect the end product or downstream components through which air flows after the compressor. To the customer, this means less expenditure on maintenance-elimination of expensive oil removal filters, frequent stoppages for oil top and oil fills in the crankcase.
Applications:
Oxygen/Nitrogen generation plants
Laboratories
Research facilities
Pharmaceutical industry
Food processing and packaging
Electronics production
Ozone generation
Printing equipment
Fermenters
Applications that are zero tolerant to oil in compressed air
The technology edge design:
Cylinder and cylinder head: Deep finned cylinders for efficient heat dissipation. Cylinder walls are specially coated for wear and corrosion resistance. Polished bore and smooth finish of the cylinders provide longer wear life of the piston rings
PTFE coated pistons and PTFE rings: Ensure longer wear life and gas-tight sealing
Stainless steel reed valves: For corrosion resistance
Single piece crankshaft: Robust and easy to assemble
Flanged aluminum aftercooler: From high-pressure cylinder for efficient cooling
Delivery unloader: For automatic unloading of the compressed air in the delivery pipelines
Twin sided belt guard: Meeting OSHA standards
Rustproof internal coating: For air receiver
Features:
Oil less compressor with a unique suction through crankcase design
Designed for industrial duty cycles
Slow running speed for lesser wear and tear
Air receiver coated internally for corrosion resistance
Base mounted and receiver mounted variants available
PTFE coated pistons, rings and sealed bearings for the lubrication of friction parts
