With thousands of installations worldwide, our Defender RMF filters have earned the reputation of the “gold standard” for recreational water and life support system filtration applications. Compared to other technologies, Defender regenerative media filters maximize performance, efficiency and user friendliness while helping reduce environmental footprint – an outcome good for the planet. The ability to remove particles as small as one micron provides the clearest, cleanest and safest aquatics environment possible. And if that’s not enough, facility operators can achieve significant savings up to the following in several key areas: Water 90%, Space 75%, Energy 50%, and Chemicals 30%.
Save up to 90% in water savings
Save up to 75% in space savings
Save up to 50% in energy savings
Award winning Defender® regenerative media filtration (RMF) systems are capable of filtering particulate down to 1 micron and require no backwash.
Introducing the newest Defender® regenerative media filter, the FP-Series, designed to deliver maximum performance for swim schools, health clubs and other small to medium size commercial aquatics venues committed to providing their guests with exceptional water quality and the lowest operational costs.

Cleaning agent approved for use on Sand and Defender® filters
For a Defender® RMF filter, the filter media is what captures all the dirt and debris. Using the recommended grade of perlite will ensure optimal performance for even the most demanding applications!

The initial capital cost of a Defender media filter is more than a sand system but is quickly offset in operational costs savings – often in less than a year. The smaller Defender system saves on construction costs, water and waste costs, energy and chemical costs as well as power costs.
No, there is no pool size limit. Defender filters may be installed on 70 – 2500 GPM (single filter) pools and spas. Multi tanks can be installed in tandem to accommodate higher flow rates.
Defender filters are programmed to complete the automated regeneration cycle daily and it will take no longer than 10 minutes. This includes the “bumping” step and agitating the media. (See also “Bumping”)
“Bumping” is the mechanical movement of the tube sheet which forces water into the tubes, evacuating the media from the surface of the tubes, sending it into suspension. It is accomplished by mechanical movement of the septum up and down within the water in the filter housing. This motion expels the media and dirt particles from the septum and into suspension. This allows the filter elements to receive a fresh coating of perlite once it re-attaches itself to the tube elements. Defender filters are programmed to bump daily and will take no longer than 10 minutes to complete.
Every Defender system is designed to be fully automatic but is operable in semi-automatic mode which requires the push of a button to initiate the automatic filtration and bump cycle.
The Defender system's programmer includes auxiliary contacts to control all peripheral devices.
The complete filter cycle using the same charge of perlite usually averages 4 weeks depending on bather load. Some pools may go months in the off-season.
Eliminating used media and recharging with new media in a single Defender system takes 15 – 25 minutes.
