Benefits of the “Always Better” AB Series
The ELGi AB Series oil-free air compressor is designed to European industrial standards and is among the best compressors at balancing energy efficiency and low cost of ownership in Europe.
Class 0 certification to ISO8573-1:2010
ELGi AB Series oil-free air compressors consistently deliver oil-free compressed air that meets ISO8573-1 Class 0 standards. The AB Series has a food-grade aluminium housing that prevents microbiological contamination. The pipes have a special e-coating that guarantees consistently clean, oil-free compressed air, while optimised rotor clearances ensure a steady delivery of compressed air.
Microbiological content to ISO8573-7:2003
These compressors discharge air that is free of microbiological contamination and meets ISO 8573-7 standards.
Pure water quality
To ensure water quality, the ELGi AB Series has a closed water circuit that eliminates the need for a reverse osmosis (RO) system. This reduces energy and maintenance costs for our customers and ensures pure water quality.
Corrosion-resistant stainless steel rotors
ELGi machines use FDA-approved stainless steel with a special coating that rules out any risk of corrosion.
Compact air-cooled package
The AB Series includes an integrated fan motor assembly with considerably reduced energy consumption that maintains a low temperature, extends motor life and offers an intelligent cooling system design for easy maintenance and ventilation.
Lower maintenance costs
The efficient, best-in-class rotors, single-stage operation, low operating speed and application-focused design of the oil-free screw air compressors lower overall maintenance costs. ELGi’s AB Series of oil-free air compressors features advanced technologies that increase efficiency and extend equipment life, reducing maintenance and downtime.
Advanced moisture separation technology for optimum compressed air quality
The ELGi AB Series offers a centrifugally formed moisture separator with automatic drain that delivers 99% moisture-free air, ensuring optimum compressed air quality. ELGi AB Series oil-free compressors maintain low airend discharge temperatures and improve moisture separation. This results in better dew point management.
Condensate water recycling in the AB Series
ELGi AB Series compressors recycle the condensate water, keeping the water circuit fresh and clean. The integrated level switch drains excess water, eliminating the need for open systems or water filtration at the compressor inlet.
Advanced controls and filtration in the AB Series
The advanced Neuron IV controller enables remote management of compressor operation and is ready for integration into SCADA/DCS systems. In addition, the AB Series has a two-stage air filter system that extends the life of consumables.

Frequently asked questions
What applications is the ELGi AB Series suitable for?
For sensitive applications in which no oil residue whatsoever is tolerated and clean, oil-free compressed air is needed.
What air quality does the AB Series deliver?
Oil-free compressed air to ISO 8573-1 Class 0. The air is also free of microbiological contamination in accordance with ISO 8573-7.
What outputs does the AB Series cover?
Motor power from 11 to 110 kW, pressures from 7 to 12 bar and flow rates from 0.85 to 15.9 m³/min.
How is the water circuit designed?
It is closed. This means no reverse osmosis system is needed, and the condensate water is recycled. A level switch drains excess water.
What are the rotors made of?
FDA-approved stainless steel with a special coating that prevents corrosion.
How does the AB Series keep maintenance costs low?
Through efficient rotors, single-stage operation, low speed and a two-stage air filter system that extends the life of consumables.
How is moisture removed from the compressed air?
A centrifugal moisture separator with automatic drain delivers 99% moisture-free air.
Can I integrate the AB Series into my control system?
Yes. The Neuron IV controller allows remote management and is ready for integration into SCADA/DCS systems. With ELGi Air~Alert you can also monitor the compressors remotely around the clock.
