WHAT IS AFM® ng?
Result of 35 years of Research and Development, AFM® ng (Activated Filter Media) is the sand substitute, which can be installed in any type of sand filter without any modifications.
Made of green and brown glass, AFM® ng has undergone a unique activation process that makes it self-sterilizing and provides it with greater mechanical and electrostatic filtration performance.
SELF-STERILIZING SURFACE: Resistant to bacterial growth.
ENLARGED CONTACT SURFACE: Mesoporous structure, for superior filtration performance.
CHARGED SURFACE: For the adsorption of the finest particles and organic matter.
- Healthier water: Prevents the transmission of pathogens (e.g. Cryptosporidium)
- The clearest water: Offers a stable filtration ratio of 1 micron.
- Healthier air: Prevents the formation of toxic byproducts and chlorine odor.
- Lowest operating costs: Savings on wash water and chemicals.
- The most sustainable filtration: More durable than all other filter media
AFM® ng, THE HIGHEST PERFORMANCE FILTER MEDIA
Thanks to its large hydrophobic area and mesoporous structure, AFM® ng can filter much finer particles (1 micron) and 50% more organic substances than sand.
Why is activation so important? Because it significantly reduces chlorine consumption and guarantees crystal-clear water and the best air quality.
AFM® ng offers the finest filtration. Filters with AFM® filters much more than quartz or glass sand.
The renowned European independent filtration laboratory IFTS (Institut de Filtration et des Techniques Separatives) has tested AFM® ng in October 2019 together with other silica sand and glass media. The tests have been carried out with the new filter media and without any biofilm, at a filtration speed of 20m/h without the addition of any type of flocculant and the results have been that AFM® ng is the only one capable of filtering 95% of particles larger than 1 micron.
How should AFM be used?® ng?
• The AFM loading in a filter is 15% less than what would be required for silica sand. This must be taken into account when calculating the AFM loading.
1 21kg AFM bag = 1 25kg sand bag (the volume is the same).
• There are three degrees:
The AFM® ng is the only medium that complies with ISO 9001-2008, Regulation 31 UK, UNE EN12902 and EN12904 regulations, TÜV Certification in Germany. In addition, it has received numerous awards such as the Barcelona Swimming Pool Show 2009, Smagua 2010, Golden Wave International 2011...
