Overview

The BKP Portable is a 304L stainless cartridge filter housing on a wheeled cart that pairs with a pump of your choice to vacuum and polish a pool without sending water to waste. Reusable cartridges handle up to 155 GPM per housing, so it clears cloudy or green water quickly without backwash. It suits service crews and facilities that need filtration where the plumbing is not, and for troubleshooting clarity problems.
