Do I have to use original manufacturer's filters and lubricant?

Most all manufacturers require you to use their filter and lubricant during warranty periods; this ensures that they are protected with products they designed with the specifications they feel are necessary to properly maintain their equipment.


How long will my oil last?

This varies depending on the type of oil. If you are using petroleum oil in a rotary screw compressor, you will need to change the lubricant every 500 to 1000 hours. If you are using a synthetic or partial synthetic, you will have a range between 4,000 hours all the way up to 12,000 hours. Make sure you know what oil you are using, as many lubricants are not compatible with each other.

Reliable Troubleshooting

Which is best for me, a rotary screw or a reciprocating compressor?


A rotary screw compressor is designed to best operate at 100 % load, 100% of the time. For example, if you are a small mechanic shop with 4 technicians, there will not be a constant air demand and a rotary screw compressor will be loading and unloading frequently, causing increased oil carryover and premature maintenance and repair needs. If you have a continuous air usage a rotary screw compressor would be well suited when sized properly.

FAQs about compressors

What makes a cycling dryer better than a non-cycling dryer?


A cycling dryer works similarly to a refrigerator. It cools a thermal mass down to a set temperature and then the compressor shuts off until the thermal mass temperature comes up enough to turn the compressor back on.


A non-cycling dryer compressor runs all of the time and there is a hot-gas by-pass valve that may need to be adjusted as ambient conditions change to maintain a specific dew point range. This makes the cycling dryer more energy efficient and less likely to freeze-up.
