Unique Features

Designed with performance in mind.

Tank Construction

All vessels are conservatively engineered and manufactured with Flexsol 3000™ interior lining and include a 10 year fully rated warranty. The lining protects all wetted surfaces against corrosion to maximize the life expectancy of the vessel.

Automation

The Model RMF programmer manages automation for all filter cycles including regeneration (bump), maintenance mode, and media transfer. Easily interfaces with chemical controllers, heaters, and variable frequency drives. Saves labor and maximizes operational security.

Vacuum Transfer

At the push of a button, a selfcontained, integrated pump quickly introduces dry media into the Defender® filter. This feature eliminates the mess and additional equipment required by wet, slurry designs.

Internal Hydraulics

Our underdrain manifold is engineered to achieve ideal distribution of influent flow. The generous open area serves to minimize turbulence and ensure superior “Flex Tube” coverage.

Lifting Davit

At some point it may be necessary to access the interior of the vessel. Our unique tankmounted davit permits easy access without remote lifting devices. The davit reduces the overall height requirement and saves valuable floor space.

It’s all about the “Bump!”

The Defender® filter is programmed to automatically “bump” on a daily basis to regenerate the media coating of the “Flex Tubes.” This incredible benefit maximizes system performance while enhancing sustainability and conservation.

 

As the bump tire deflates (A), the tube sheet lowers to loosen the media and trapped debris. The re-inflation of the bump tire (B) raises the tube sheet and forces water into the “Flex Tubes”, gently expanding them to fully release all material. This bump cycle pulses ten times to ensure the entire cleansing process.

At the completion of the bump cycle, the Defender® will automatically pre-coat the “Flex Tubes” and re-commence the filter cycle. The “Bump” is a vital function in order to achieve superior filtration and to make the most out of every filter cycle.

“Neptune-Benson was part of our design/build team when Splish Splash Waterpark was built in 1991. Through 6 expansions and work at several additional parks around the US, Neptune-Benson has provided quality products and fantastic support to keep us coming back whenever we need filtration systems or friendly advice.”

Filter Elements

Our “Flex Tubes” are constructed of T304L stainless steel frames (optional T316L) with permanent polyester woven coverings. Not one has ever had to be replaced as a result of wear. Other systems designed with rigid plastic frames, o-rings and socks require costly replacement and frequent maintenance.
