After a long winter, we could all use some sunshine and longer days. With spring, there’s pollen and warmer temperatures. Both of which air compressors are not too fond of. Here are a few things to check to keep your rotor screw air compressors running smoothly and avoid costly downtime:
- Check your air entry points. You don’t want them to clog. Clogging will affect compressed air output and prevent air from properly flowing through and keeping your compressor cool. Properly maintained air filters can keep your production running efficiently. Clogged filters make the compressor utilize more energy. As energy increases, it increases your cost of production.
- Check any plastic tubing that may have cracked during freezing temperatures.
- Check your engine and compressor oil. We recommend that you take an oil sample from your compressor every quarter to check for the equipment’s health. Drawing an oil sample helps determine if the oil needs to be replaced. Further, the presence of impurities like excessive sludge, grime, or metal flakes can also be an important warning sign. If the oil gets low, it can cause the air compressor’s temperature to rise and cause your air compressor to overheat and shut down.
- Check your cooler for pollen, dust, insects, and debris.
- Check your compressors’ intake filter. It’s common to find dirt or pollen collected in your intake filter. A clogged intake vent can cause issues to your compressor, so be sure to check this regularly throughout the spring season.
- Make sure your compressor is well-ventilated! You also want to make sure your fans and louvers are all functional to keep your compressor cool during the warm weather. A well-ventilated compressor works more efficiently and keeps the operating temperature down.
- Perform any due preventative maintenance.
- Keeping your air compressor on a regular service schedule is key to performing optimally and fulling its lifespan.
The checklist below is general maintenance interval guidelines. We recommend following the list below to ensure smooth operations all year long.
