The original Dayliff high-rate GRP filter was introduced nearly 35 years ago, initially designated GP but for some time now DX and CX and in this time the familiar yellow tank has become the standard filter fitted to most swimming pools as well as water treatment plants in the region.

Filter production recently achieved a major milestone when number 20,000 was made, the first 10,000 taking over 25 years to be produced, the second only 7years! Available in five diameters and various configurations, the filters are manufactured in the company's Dundori Road facility. They remain very popular and number 30,000 is now the next target!
