DELPARK
FILTER-MATIC

Automatic self-cleaning vacuum filter

The Delpark Filter-Matic is a self-cleaning vacuum filter used for industrial coolants.  It provides continuous, uniform coolant filtration.  The Filter-Matic is a low cost, minimum maintenance system with automatic sludge removal.  It also provides for high flow rates, with or without precoat and no down-time.

Automatic Filtration

The Filter-Matic consists of a two compartment reservoir - a filter tank and a clean oil tank.  unfiltered liquid from the filter tank is drawn by vacuum through either leaf or tube filter elements.  Solids are deposited on the surface of the elements, and clean coolant is pumped through a four-way valve to the clean storage tank.   As contamination deposits form a cake on the filter elements, flow is restricted causing the liquid level in the filter tank to rise.  At a predetermined level, a timer control or float actuates a solenoid air valve which turns the four-way valve to reverse liquid flow through the filter.  Clean coolant backwashes deposits off the elements, and chain driven flights remove the residue to a tote box as it settles to the bottom of the filter tank.  Positive backwashing does not interrupt continuous flow from the clean tank to the machine tool.  At the completion of the backwash cycle, filtration is automatically resumed.

Flexibility

Delpark Filter-Matics are designed for existing space requirements and in a wide range of flow rates for individual machines or central systems.  They are adaptable to various industrial coolants such as synthetics, soluble oil, mineral oil and other petroleum products where clean coolant or oil is a must to maintain required finishes and tolerances.
