Common Air Compressor Problems

Air compressors are useful in a number of different industries. Construction crews use air compressors to power their nail guns, while painters use them in powered spray paint guns. They’re also useful in cleaning up sawdust, working on vehicles, and many other situations. Like all equipment, your air compressor will eventually need maintenance or repairs. Even the highest quality equipment doesn’t last forever. Here are some of the common problems you may experience with your air compressor and key symptoms that will help you identify what’s wrong.

The Compressor Doesn’t Come on or Work

When you can’t even get your compressor to activate, you may have a serious issue, although sometimes it’s actually very simple. The power may be off for some reason, or you may need to hit the reset button. The problem could also be low oil. Other times, though, it can be a little harder to diagnose. For example, the pressure switch may not be making full contact, or the tank may have low pressure. In some cases, you may need to replace the entire pressure switch.

The Compressor Makes Loud Noises

If you’re using your compressor and it starts to make loud noises, you may have something loose. It could be a belt, the pulley, the flywheel, a clamp, a belt guard, or one of a number of other things. You could also need to add oil because there may not be enough lubricating the bearings. It’s also possible that a piston is hitting the compressor’s valve plate, that the crankcase is defective, or that the floor mounting has come loose.

If you find that the crankcase needs replaced or that your compressor needs a new gasket, you may want to call an air compressor service. These experts can come to your manufacturing plant, job site, or other location and repair your compressor. They can work on any make or model of air compressor and have years of experience in the industry.

The Oil in the Oil Reservoir Appears Milky in Colour

If the oil in the compressor’s oil reservoir has taken on a milky appearance, it means that water has somehow gotten into the oil reservoir. This often happens if you’re using your air compressor in an area with high humidity. Dealing with this issue may be irritating since moisture will continue to invade the oil reservoir as long as you work in the high humidity. You can drain the oil tank regularly, clean it, and replace the air cleaner component, or change the oil more often to help keep the oil reservoir moisture-free.

The Compressor Is Vibrating Excessively

This is another problem that may or may not have a simple answer. It could be that the mounting bolts simply need to be tightened or that your air compressor hasn’t been properly mounted. However, it could be something more difficult to diagnose and fix. The crankshaft may be bent, for example, or you may have a belt loose somewhere.
