Doulton Ceramic Filter Elements

Doulton ceramic drinking water filter elements utilize the natural properties of high purity specialized diatomaceous earths to provide a range of strictly controlled pore sizes giving maximum filtration efficiency together with high porosity for maximum flow. Doulton ceramic filter elements can be quickly and easily cleaned many times to prolong their working life.

The filter elements are produced using the latest ceramic techniques to provide a hollow porous ceramic which is fired at a temperature in excess of 1000 C. They are designed to operate with water flow going from the outside to the inside of the ceramic element. A variety of dedicated fillings can be placed inside the bore of the element to combat specific water contamination problems. For more details see Doulton drinking water filtration technology.

All the regular elements are produced in two inch (49 mm) nominal diameter. Standard lengths are five inch (13 cm), seven inch (I 8 cm), and ten inch (25 cm). For mounting purposes all candle elements are traditionally supplied with a food grade plastic mount which terminates in a 1/4inch BSP male thread. There are two standard length mounts; the long (L) mount is 1-5/8 inch (41 mm) long used in gravity filters, the short (S) mount is 3/4inch (19 mm) long used in pressure systems as well on most gravity filters.
