What is the difference between oil-free and oil-injected air compressors?

Oil-free compressors deliver ISO 8573-1 CLASS 0 air, containing no oil, suitable for food, pharma, and electronics. Oil-injected compressors are more economical for general industry but require downstream filters to remove oil carryover.

What is the typical payback period for a VSD compressor?

For a 100 HP compressor running 5000 hours/year with electricity at $0.10/kWh, the payback period is typically 12-24 months. Higher load variation or electricity rates shorten payback. Request our free energy audit for an accurate estimate.

Can Raydafon compressors be used in hazardous areas (ATEX)?

Yes, our special gas compressors can be supplied with ATEX Zone 1/2 certification, explosion-proof motors (Ex d IIB T4), and gas detection systems. We also offer IECEx certified units. Please provide your zone classification and gas group for a custom solution.

How much energy can I save with a VSD compressor?

Variable Speed Drive compressors save 30-40% energy compared to fixed-speed models, especially in fluctuating load applications.

What maintenance does an oil-free screw compressor require?

Oil-free screw compressors need air filter and water separator replacements every 2000-4000 hours, and major overhaul of airends after 50,000-80,000 hours. No oil changes required.

Are Raydafon compressors ATEX certified?

Yes, our special gas compressors can be supplied with ATEX Zone 1/2 certification, explosion-proof motors, and gas detection systems. Please consult our engineers for your specific environment.
