FREQUENTLY ASKED QUESTIONS

What is the difference between an oil-injected and oil-free compressor?

Oil-lubricated compressors use oil for lubrication, cooling, and sealing, while oil-free compressors use special materials or technologies (like a special coating or water injection) instead of oil to prevent contamination.

Can oil-lubricated compressors be used in food processing industries?

Yes, but with appropriate filtration systems to ensure compliance with industry standards for compressed air purity.

ELGi recommends using an oil-free air compressor for maximum compliance with regulations. However, an appropriate filtration system, paired with food-grade oil can be sufficient for certain food processing applications.

What are the advantages of using an oil-lubricated compressor over other types?

Oil-lubricated compressors offer higher power output for heavy-duty tasks, Lower initial cost, Versatility for various industrial applications, smoother and quieter operation.

Is the EN Series Oil Lubricated Compressor suitable for environmentally conscious businesses?

Yes, the EN Series Oil Lubricated compressor is designed to meet environmental standards and emissions regulations, making it suitable for businesses focused on reducing their environmental footprint and promoting sustainability.

How frequently should I replace the oil in my oil-lubricated compressor?

It is recommended to perform an oil change for oil-lubricated compressors like the EG Series approximately every 2000 to 8000 operating hours. Regular changing of the oil ensures optimal performance, extends the compressor’s lifespan, and helps maintain efficiency in your operations. It is essential to follow the manufacturer’s guidelines and conducting routine maintenance will ensure your compressor operates smoothly and reliably.

How do I maintain my oil-lubricated compressor to ensure optimal performance and longevity?

Regular oil top up or oil change with clean oil ensures proper lubrication and efficient operation.
