Enviroquip® Folded Plate Filter Underdrain
The Enviroquip® folded plate filter underdrain is synonymous with proven performance in gravity filtration. A low profile and media retaining design allows for deeper media stacks than what is available with other underdrains. Our 0.25mm openings place filter media directly on the underdrains and air laterals. The uniform introduction of air and water through separate conduits provides superior simultaneous air/water cleaning. The system can be installed new or retrofit into existing filters.
