MAAS MIDWEST is now offering its SANDBLOCKER Well Screen in a new 6-inch pipe size. The patented design has stainless steel fiber wool encased between out and inner stainless steel perforated tubes. The stainless steel fiber wool retains fine sands from entering the well with the equivalent performance of a three slot, yet it allows up to 25 gpm of water flow per foot of screen. Slot sizing of sand is not necessary since SANDBLOCKER covers all ranges of slot sizes from three or larger.
