The Prab candle filter is specifically engineered to meet the challenges of removing fine particulate from spent oil in honing and EDM machining applications and Tungsten carbide tool and steel ball grinding applications. This filter uses a permanent media in a long cylinder that houses more than 10,000 thin membrane wafers. These membranes are designed effectively and consistently capture grinding swarf at 1 micron. These filters operate with virtually no downtime for maintenance. The self-cleaning, air driven backwash system automatically clears the filter of dirt and debris allowing the candle filter to perform reliably under long production runs.

The filter is engineered for oil filtration in EDM, tungsten carbide tool grinding, electrical discharge machine, honing machine, and bearing grinder applications. Permanent membrane wafers trap grinding swarf at 1-3 microns. Automatic air pressure back flush cycle is designed to reduce labor costs and increase process efficiency. Swarf and oil is purged into an external receptacle for easy collection and recycle, according to Prab. The optional chiller ensures constant fluid temperature, varying only 1-3 oF, to maximize tool life and part quality.
