RCI FP4000 Fuel Purifier for Bulk Diesel Filtration Units

The RCI Technologies purifier is a simple one step unit that removes 99% of water and 95% to 98% of heavy particulates, down to approximately 10 microns. Even today’s “clean” diesel fuel will easily become contaminated during transportation and storage.

Unlike all other products on the market, the RCI Technologies purifier performs this function without the use of a replaceable, changeable, or cleanable filter element, cartridge or bowl.

By removing contamination immediately before the fuel enters the engine’s filter system, the purifier delivers cleaner fuel, (virtually eliminating filter clogging) and therefore greatly extending maintenance intervals.
