Air Preparation Units, commonly known as F.R.L. units (Filter, Regulator, Lubricator), are essential devices used to condition compressed air before it enters pneumatic tools, cylinders, valves, and other automation equipment. Raw compressed air from a compressor contains moisture, dust, oil, and other contaminants that can damage equipment, reduce efficiency, and shorten service life. Air preparation units clean, control, and lubricate the air to ensure optimal performance and reliability of your entire pneumatic system. They act as the "lungs" of the machine – filtering impurities, regulating pressure, and providing lubrication.
