Efficlean is a filter that separates solid from liquid at micron levels, even to the extent of 0.25 microns. Works on the principle of centrifugal action, where oil will be circulated for a predefined number of passes as recommended, and cleaned oil sent back to the tank. This is a bypass filter, with a separate pump for inlet pressure requirements of 2.5 to 7.0 bar depending on medium to be filtered. This pressure energy is converted to rotational energy in Efficlean, which causes particles to accumulate layer by layer in the rotor walls. Cleaned oil from Efficlean is routed back to the tank by gravitational forces.
