Where to Add Oil to an Air Compressor?

It is located on the oil and gas tank, with the drain at the bottom and the fill in the middle. Here are some related introductions about air compressors: 1. The use of air compressor oil: Air compressor oil can reduce friction on various types of machinery, protecting mechanical parts and workpieces as a liquid lubricant, primarily serving functions such as lubrication, cooling, rust prevention, cleaning, sealing, and buffering. 2. Common types of air compressors: Common air compressors include piston air compressors, screw air compressors (which are further divided into twin-screw and single-screw air compressors), centrifugal compressors, as well as sliding vane air compressors and scroll air compressors.
My old piston air compressor has the oil filler port on the side with a graduated round sight glass. Look for the plastic screw cap marked 'OIL' below the side panel, unscrew it counterclockwise to refill. Remember to use dedicated compressor oil - regular engine oil will coke at high temperatures. I usually fill to just above the midpoint of the sight glass, then tighten the cap. Checking oil level before each startup is crucial - this maintenance round revealed coupling wear caused by last oil shortage. After refilling, wipe off any oil spills to prevent dust buildup clogging the intake valve.
