Suitable for high purity applications the Aqualyze pure water housing is designed as a simple three part construction with the head and sump secured tightly together using the threaded collar. Accepting 222 style/solid end o-ring filter cartridges, the exceptionally smooth surfaces prevent particulate adhesion making the perfect combination for producing water of high purity. The SFH natural housing comes as standard with a spanner, stainless steel bracket and assembly kit and pre-drilled sump and gauge ports.
