Oil-free piston compressors draw atmospheric air within a cylinder where it is compressed due to the actuating motion of the piston inside the cylinders. They are less expensive, lighter in weight and produce as much airflow (CFM) & pressure (psi) as many oil-lubricated models.
ELGiโs range of oil free reciprocating air compressors offers 100 percent oil-free compressed air solutions which are designed to provide zero risk of contamination with improved energy efficiency and long-term reliability to meet the precise needs of a diverse range of industries such as pharmaceuticals, food & beverage, electronics and textiles that cannot tolerate any chance of oil contamination in their processes.
ELGi oil-free air compressors are a versatile solution for various industries that require clean, contaminant free air. In the food and beverage sector, they ensure safe product handling for packaging and processing. Similarly, the electronics and pharmaceutical industries can rely on ELGiโs oil-free technology to prevent contamination in sensitive manufacturing and packing environments.
0 oil standards. Food-grade coating is applied where air contacts the metal surface inside the compressor ensuring consistent oil-free air without metal debris. Pipes have special e-coating that ensures consistently clean and oil-free air and optimised rotor clearances ensure consistent air delivery.
ELGi’s oil free air compressor technology optimises ย your operation’s productivity by eliminating energy waste in pressure drops. The two-stage oil free compressors are designed to make maintenance easy over reduced operating costs by providing clear access to air components.
ELGi is among the very few air compressor companies to 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 unique eta-V rotor design reduces pressure losses and increases stage efficiencies, leading to an optimised compressed air system.
Our airend rotors and housing are coated with PTFE-based food-grade PP coating to resist corrosion and endure high temperatures up to 250 degrees C. This results in optimum long-term performance with no loss in efficiency.
