Frequently Asked Questions
What is an oil less air compressor?
An oil less air compressor uses permanently lubricated bearings and piston rings instead of oil for lubrication. This eliminates the need for oil changes and reduces maintenance. It also produces cleaner air with less oil carryover, making it suitable for painting and other applications where oil contamination is a concern.
Are oil less air compressors less durable than oil-lubricated ones?
Historically, oil less compressors were considered less durable, but modern designs have improved significantly. Many oil less models now have comparable lifespans to oil-lubricated units for home and light professional use. However, for heavy continuous duty, oil-lubricated compressors may still last longer. Always check the duty cycle and warranty.
Can I use an oil less air compressor for painting?
Yes, oil less compressors are often preferred for painting because they produce cleaner air with less risk of oil contamination. However, you should still use a water separator and filter to remove moisture and particulates for best results.
How loud are oil less air compressors?
Noise levels vary widely. Some models like the California Air Tools 10020C operate at 70 dB, while others like the PORTER-CABLE C2002 can reach 82 dB. Generally, oil less compressors tend to be quieter than traditional oil-lubricated ones, but not always. Check the decibel rating before purchase.
What size oil less air compressor do I need for engine oil tasks?
For topping off engine oil or powering a small impact wrench, a 4-6 gallon tank with 1-2 HP is usually sufficient. For continuous use like sandblasting, you may need an 8+ gallon tank. Consider the CFM requirements of your tools and match the compressor’s output accordingly.
