For a considerable time, Allen Filters, Inc. has marketed Allen Oil Conditioner as being the best available and most cost-effective technology.

The Allen Oil Conditioner system consists of a heavy-duty vacuum pump capable of maintaining in excess of 10-3 Torr of vacuum. This is coupled with a Vacuum Distillation column with patented internals that facilitate vaporization of contaminants. An integral part of the system is pre- and post-filtration of 5 micron and 0.5 micron respectively.

The system is compact, designed to operate continuously without operator attendance, and is available in many capacities.
