Ostoform FLOWASSIST Drainable Pouch.This item forms one half of a 2-piece pouching system. The FLOWASSIST Drainable Pouch is made from Polyethylene Fleece, a fast-drying material that prevents electrostatic build-up. It includes an activated carbon filter and Moisture Protect Composition (MPC) filter technology, an additional protective layer that protects the activated carbon filter against liquid absorption. Additionally, it features a set-in window, hook-and-loop fastener for securing the drainable outlet, and an integrated coupling system for attachment to the baseplate by pressing the two plastic click rings around the floating flange.
