An air compressor is used to compress and pressurize the air. These devices have a wide range of application including pharmaceuticals, food processing industries, transporting liquid chemicals among others. Many users of air compressors forget that an ounce of prevention is worth a pound of cure. Carrying out maintenance on the air compressor can save money and time down the road. Here are some checks that you should consider performing every time you operate your unit to ensure its efficiency and longevity.

Checking the compressor unit pump oil level

Some compressors use oil to operate while others don't. If your equipment uses oil, it is not advisable to operate it without lubricant. Note that the manufacturer or the company from whom you bought the device cannot be responsible for failure due to inadequate lubrication. Here is how to check the pump oil level:

  • Turn off the unit and disconnect it from the power source
  • Make sure that the equipment is on a flat and level surface
  • Remove the plug or fill cap
  • Check the oil in the crankcase and also inspect for dirt or debris
  • Check through the sight glass and if need be, add the oil to the halfway point.

How to change compressor pump oil

When changing the pump oil, you should take safety precautions as the compressor pump head as well as the surrounding parts could probably be hot. Here is the procedure to follow:

  • Turn off the unit and ensure that it is disconnected from the power source
  • Remove the fill cap or plug
  • Place the collection container under the oil drain cap
  • Then, remove the drain cap, and allow the oil to drain out
  • Replace the oil cap and make sure that you have tightened the nut securely. Use white plumbers tape to create a tighter seal. Then, fill the crankcase with appropriate oil up to the half way point.

Checking and replacing the air filter element

Air entering the unit for compression must first be filtered or purified. Filtering the air helps to prevent air contaminants that can not only shorten the life of your equipment, but can also spoil the product or the process from entering the air compressor.  Dirty or malfunctioning air filter elements can allow debris or other contaminants pass through to the delicate pars of your equipment. Regular inspection and changing filter elements when necessary is quite important.

  • To check and replace the air filter element, follow this procedure:
  • Turn off the unit and disconnect it from the power source and allow the pump to cool off
  • Unscrew the filter top from the base by turning counterclockwise
  • Remove the element from the filter base
  • Clean the filter element by blowing it using compressed air
  • If the element is damaged, replace it
  • Screw the filter top to the base and secure the filter

Performing the above preventive maintenance will keep your equipment running smoothly. (For questions regarding air filters, contact a company such as Air Chief Inc)
