The central filtration system pictured was provided to Ford Motor Company for the Duretec 35 engine program. The application is aluminum head machining, utilizing fifty-six Huller CNC machines. The central filtration system was designed to filter 7600 gpm of water-based coolant and recycle 600 lbs./hr. of aluminum chips.

The filter system included two model HV-9D Hydro-Vac vacuum filters, each with 100 micron permanent media, a center mounted strainer conveyor with 750 micron permanent media, clean tank, heat exchanger, system supply pumps, and control panel. The dirty coolant first enters Filtra-Systems patented belted strainer conveyor, where 80% of the chip load is removed.

The strained coolant is then directed to two Hydro-Vac vacuum filters where the remaining chips are removed and the coolant is filtered to less than ten part per million greater than ten microns. The clean coolant is then pump through heat exchangers, to maintain a constant temperature of 72 F, and back to the machine tools at 75 psig.

The Hydro-Vac filters have patented pneumatic side seals, which significantly improve coolant clarity, and the ability to operate with permanent media, disposable media or both, simultaneously.

For the Duretec 35 engine headline, Filtra-Systems supplied simultaneous engineering, design, manufacturing, integration and delivery of the complete Hydro-Vac vacuum filter system shown.

"This system was chosen for its innovative design, simple operation and low life cycle cost"

The complete system was designed for installation on the plant floor, as shown, and the entire system was fully assembled, wired and functionally tested, on Filtra-System's manufacturing floor, before shipment to Ford Motor Company.

This application is a good example of how Filtra-Systems designs and builds complete filtration & separation systems including; not only the filters, but also the fluid transfer technologies; Hydrolifts, pumpstations, machine-base trench, and pipe return systems, which support the filters.

The headline is made up of fifty-six individual CNC machines. The coolant and aluminum chips are flushed from each machine into a floor mounted pumpstations located at each machine. The pumpstation includes a Chopper Pump which chops the chips and pumps the coolant into an overhead-piping header where the chips and coolant flow by gravity back to the filter system.

Filtra-systems designs and manufactures all the fluid transfer technologies necessary for a plant floor installation of your central coolant filtration system. Filtra-Systems is the technology leader in the machine tool coolant filtration industry and continues its lead through innovation. Exemplifying this, the four filtration and separation systems supplied to Ford for the Duretec 35 program are each covered by five U.S. patents.
