Oil Analysis is an extremely important part of taking care of your air compressor. It is a preventive maintenance procedure that helps identify future problems before they arise. It’s kind of like a blood test for your air compressor. It helps you find current issues that can become costly problems in the future. Oil analysis varies between different compressors but let’s talk about the major industrial compressors; rotary screw air compressor and reciprocating or piston compressors. It is recommended to sample the oil around 180 days for reciprocating air compressors and at the 1000 hour mark for rotary screw compressors. So what exactly are you looking for during these oil analyses? We’ve got one word for you, ‘Contaminants’. Every single contaminant is an indicator of different problem areas. Whether it’s water or different metals, it’ll be a step in the right direction to find the actual source of the problem. Some of the common things to look for are Water, Iron, Chromium, Nickel, Aluminum, Lead, Copper, Tin, Silver, Titanium, Vanadium, Silicon, Sodium, Potassium, Boron, Molybdenum, Phosphorus, Zinc, Calcium, Barium, Magnesium, and Antimony. The quantity of these is measured against the average and then one is able to make a judgement whether something is excessive in quantity. The excessive amount of any of these contaminants is a great first step to identify any problem areas within your air compressor. Sometimes the problem isn’t within the air compressor but rather the surrounding air. The compressor needs to be stored according to it’s recommended temperature of storage and it needs to have clean air to pull in. There’s only so much your air compressor’s filters can catch, everything else will continue to cause harm to your machine. The benefits of a regular oil analysis are endless.
