Haws Axion MSR 10-5/8-inches ABS green plastic drench shower head delivers dispersed flow for uniform drenching. This new hydrodynamic design minimizes the strong physical pressure that drives the water to the outer rim making the distribution equal across the entire footprint of the flow. Better use of the water flowing through the shower makes it more effective while providing a more comfortable environment by breaking the streams of water into smaller individual droplets. Inlet 1-inches IPS. The violent showerhead flows of the past have been replaced by breaking the streams of water into smaller individual droplets to provide a more comfortable shower environment. Specifically, this shower head can be used with almost any Haws shower or combination model, with the use of a 1-inches IPS inlet. Hydrodynamic designed green ABS plastic shower head with 20 gpm flow control.
