Assessing And Troubleshooting Compressor Unit Failure

There are times where you can't keep an air compressor in perfect condition. Whether you're pumping up tires for a construction zone rush or trying to power pneumatic tools to stay productive, you may have to deal with rain, dusty winds or any combination of foul weather. A few inspection and troubleshooting techniques can help you figure out the problem and repair your air compressor, or at least know what to expect for repairs and replacements.

Filter Debris Drying Can Wreck A System

Air compressors rely on a fairly strict mesh design for filtering debris from the air. Small dust particles can damage the storage tank and other parts of the compressor and may absorb moisture, which can weaken the air quality.

If you're using an air compressor during rainy conditions, the debris can stick to the filter. For most basic filters, the wet mixture of rainwater and debris can be wiped off or brushed off easily. You may even be able to use basic devices with a bit of strained effect.

Air compressors work much faster and can fail critically. When high power air is pulled against a clogged air compressor, the motor can overheat and burn out. This is usually the case for most travel-use air compressors, but can happen to rotary screw air compressors used in construction sites when working in inclement weather.

You'll need to replace the motor in the event of a burnout. Take note of your air compressor's model number and contact the manufacturer for a replacement part number. You can get the part from air compressor dealers such as Kruge-Air Inc if you don't want to wait on the shipping from the manufacturer.

Make sure to replace the filter before using a repair air compressor, and consider a weekly maintenance plan along with a bad weather cleaning plan for the future.

Inspect Hose And Fittings For Cracks

If the air pressure is low when filling inflatables or powering pneumatic devices, the hose or hose fittings may be damaged. Unfortunately, it's far too easy to damage stock hoses.

When hoses are bent and stored improperly for too long, they may begin to crack. Drastic, sharp angles can weaken the inner lining, and changes in temperatures may speed the cracking process.

To find the specific cracks, run your fingers along the hose while the air compressor is on. If you're unable to feel any air leaking, place the hose in a tub of water and search for bubbles. A stream of bubbles should rise from areas where air can escape. It's best to replace these hoses, as temporary patches and tape can weaken and burst after time.

Contact an air compressor technician to find out what you need for a specific model repair.
