Our filtration rigs work on kidney style filtration setup. So no machine downtime is required. No loss of production! To get the best results from external filtration it really is quite simple, “the longer an oil filter rig can be operated for, the cleaner the oil will become”. Rigs will filter down to 3 micron and remove water – all from one filter. No need for two or three cannister style filters. These simple depth filters do the job with one filter.

​Generally external filtration relies on the ‘kidney looping’ or ‘bypass filtration’ process, the recycling of oil within the same tank or container. This allows the machine to operate in production, as you are not diverting any oil away from its primary function.

​For the best results the suction line should be as close to the bottom of the tank as is possible with the return line at the top of the tank under the liquor line. If there is a drain port fitted on the tank then if it is possible connect the suction line to this point and return to the tank top this helps to provide circulation ensuring all the oil gets filtered.

​Please note: If the system is pressurised during the machine operating procedure do not attempt to filter the oil. With these systems the machine must be stopped and the pressure released under the machine/manufacturers guidelines before any connection is made for filtration. With a normal un-pressurised system the machine can be run during filtration.
