An air cleaner utilizing a series of elongate, inverted U-shaped air foils is disclosed herein. An oil retaining tray is disposed adjacent the air inlet of an enclosure which also has an air outlet. The air foils are disposed in the air inlet above the tray with the legs of the air foils extending downwardly to proximate the top of the tray. A fan is utilized to force air through the air inlet, over the legs of the air foils and then up through the inside of the air foils. Air and particles of dirt entrained in the air are accelerated along the legs of the air foils. The dirt particles attain sufficient inertia to plunge into the oil in the tray where those particles are retained while the clean air passes into the inside of the air foils.
