Pressure Free Systems
The TF units are designed for hydraulic and lubricating oils. It is NOT intended for pressurised systems or where the cleaning unit is placed lower than the system it shall clean. The TF units have the ability to ‘lift/suck’ oil into the filter, but must have ‘free fall’ (fall back by gravity) back to the tank/oil reservoir. The TF unit can also be installed on top of an external oil tank for 'off system cleaining' of the oil.
