Oil mist contaminated atmosphere is an environmental and health issue that can also increase maintenance costs to air intakes and other equipment. AUSFIL oil mist separator cartridges utilize specially formulated micro glass which absorbs and retains oil carried over with the air and an inner layer of non-woven material which tracks the oil down to the oil sump for scavenging back to the main supply. All metal surfaces are protected with top and bottom cap sealed to the main body using heavy-duty polymer cement and gasket, if required. These cartridges are strictly non cleanable.
