Q:

What is air compressor oil?

A:

Air compressor oil is a specific type of lubricant that serves various purposes in an air compressor. Depending on the type of compressor, it may act solely to lubricate the various bearings and other moving parts, or it may also play a role in cooling the compressor down and helping to create a seal between its various parts.

Not all piston driven air compressors require oil, but in those that do, the oil works to keep the piston pins, cylinder bearings, main bearings and the inside of the compressor cylinder lubricated. In this type of compressor, the oil also plays an important role in preventing rust, as water often condenses inside the compressor as it cools down.

The other major type of air compressor is a screw-type, and all of these compressors require oil. In these compressors, the oil also is necessary to help cool the screw mechanism down, otherwise the screw would likely be destroyed by the excessive heat.

In the past, most air compressor oils were made from petroleum, although as of 2014, nearly all oils are synthetic. Synthetic oils are used because they are able to last much longer, often providing as much as 8,000 hours of running time, compared to only about 1,000 hours with petroleum based oil.

  • Q:

    How do you calculate the CFM of an air compressor?

    A:

    To calculate the CFM (Cubic Feet per Meter) of an air compressor is the same as calculating the output of the compressor. Calculating CFM begins with looking at the specifications of the compressor to find the volume of the tank. The next step is checking technical specifications of the sheet to find out the pounds per square inch (PSI). Calculating the PSI is followed by getting the compressor’s CFM.

  • Q:

    What type of oil does an air compressor use?

    A:

    Air compressors that are portable frequently use 20 or 30 weight non-detergent motor oils. The 20 or 30 weight non-detergent motor oil can be found at most regular auto stores. It is not necessary to purchase oil labeled as compressor oil, and some manufacturers of air compressors even approve the use of 10W-30 synthetic oil in their machines.

  • Q:

    How do air compressors function?

    A:

    For an air compressor to function, a solitary motor on the compressor converts electrical energy into kinetic energy, according to Popular Mechanics. Compressors increase air pressure by concurrently diminishing the size of the space holding the air, and this is done with two reciprocating pistons. As pistons move down, a vacuum is created above them.

  • Q:

    How do you fix an air compressor hose?

    A:

    Fixing an air compressor hose begins with determining the extent of the damage. Cut the damaged part with an appropriate cutting tool such as an X-Acto knife, throw it away and then check the ends of the hose you have cut to ensure they have clean square cuts. Hold the two sections of the hose using a hose clamp, and insert the hose ends over the brass coupling.
