Oil-Free Piston Air Compressors

Why Oil-free Piston compressors from ELGi?

Oil-free reciprocating compressors draw air within a cylinder that is pre-lubricated for permanent lubrication. This helps produce compressed air of a quality identical to the intake air, which helps the air remain oil-free. These types of air compressors are less expensive and lighter in weight and produce as much airflow (CFM) and pressure (psi) as many of the oil-lubricated models.

ELGi’s oil-free piston air compressors provide clean, Class 0 air, eliminating the risk of contamination for sensitive applications. This results in high-quality output in medicines, food and beverage, electronics, and textile applications. The ELGi oil-free technology also boasts great energy efficiency, minimal maintenance downtime, and constant reliability. Experience the ELGi difference: unrivalled purity, maximum efficiency, and long-term dependability. Contact us today to learn how our oil-free reciprocating air compressors may help your operations achieve new levels of performance and peace of mind.

CLASS 0 OIL-FREE AIR SOLUTION

ELGi’s oil-free compressors provide consistent oil-free air that meets the ISO8573-1 class 0 standards. The part where the air comes in direct contact with the metal surface inside the compressor is coated with food-grade material, ensuring consistent oil-free air without metal debris. Our pipes have special e-coating, ensuring consistent clean and oil-free air along with optimised rotor clearances ensuring consistent air delivery.

REDUCED COST OF OWNERSHIP

ELGi’s oil-free air technology helps optimise your operations’ productivity by eliminating the energy wasted during pressure drops. Our compressors are also designed to ease maintenance by providing clear access to air components.

DISTINCTIVE DESIGN AND OWNERSHIP OF TECHNOLOGY

ELGi is among the few air compressor companies that design and manufacture oil-free airends. With our in-house oil-free technology, the compressors are engineered to deliver maximum uptime and reliability. ELGi’s two-stage oil-free piston air compressors have a unique eta-V rotor design that reduces pressure losses and increases stage efficiencies, leading to an optimised compressed air system.

HIGHEST EFFICIENCY AND RELIABILITY

ELGi’s airend rotors and housing are coated with PTFE based food-grade PP coating to resist corrosion and endure high temperatures up to 250°C. This results in optimum long-term performance with no loss in efficiency.

Understanding the Differences Between Rotary Screw and Reciprocating Air Compressors

The two most commonly used types of air compressors are rotary screw compressors and reciprocating compressors.

Understanding servicing & maintenance of air compressors

Air compressors require regular servicing and maintenance, a fact that many overlook.
