Dryden Aqua AFM (activated filter Material) is an activated filtering medium for pool sand filters, with properties and performance superior to sand or conventional crushed glass, filtering 30% more organic matter.
At a speed of 20 m/h, a nominal filtration of 5 microns is obtained without flocculation
Thanks to its smaller specific weight, it takes 15% less AFM than sand. For example, if the filter contains 150 kg of sand, only 125 kg of AFM will be needed.
Complies with UNE-EN 12904 and ISO 9001:2008 standards.
Filtering medium with better results according to the independent study carried out by IFTS (Institut de la Filtration et des techniques Séparatives). Complete analysis on the Web of the pools.
Presentation in sacks of 21 kg (equivalent and with the same volume as 1 sack of sand of 25 kg).
It is supplied in three different grades to be used according to the proportions indicated in the enclosed table.
