Understanding Coalescing Technology in Modern Air Oil Separator Filters Coalescing is all about combining small particles into larger ones, making them easier to capture. Inside an air oil separator filter, a special media traps fine oil droplets suspended in compressed air. As the droplets pass through the filter, they collide and merge, forming bigger drops. Gravity then pulls these larger drops down into a collection area, where the oil can be drained or returned to the system.
