Spin-Spray Technology
Spin-spray technology lets Phiz produce a quality shower that doesn’t sting, yet it’s energetic enough to wash conditioner out of long hair.
What's wrong with existing showerheads?
Typical water-conserving showerheads make a stream that is too weak, too stinging, or too small. Some low-flow shower designs simply restrict the water flow as it enters the showerhead. This effectively lowers the supply pressure and results in a weak shower.
Other designs use extra-small holes to reduce water flow, or even use compressed air to energize the water flow, but these approaches result in a stinging shower. Reducing the total number of holes in a showerhead saves water, but it also makes the overall shower stream too small for a satisfying shower.
Spin-spray technology lets Phiz avoid these drawbacks and generate a water-conserving shower stream that is just right.
How does Phiz work?
By using a narrow, aerated stream of water Phiz produces a comfortable but energetic spray. By spinning the narrow stream Phiz transforms it into a useful shower. As a result the Phiz showerhead works well at supply pressures as low as 20psi. Low supply pressures mean very low flow rates: since the Phiz showerheads are rated at 80psi supply pressure, running them at 20psi results in actual flows much lower than their ratings.
The cut-away views show what’s inside the Phiz showerhead (click to enlarge). A pair of aerator discs sit above a spinner tube which is held in a pair of bearings. The outer body holds all the parts together and protects the spinner tube.
What happens to the water on its way through the Phiz showerhead? First, water enters the showerhead through the shower fitting. Next, a narrow stream of water is formed by the aerator discs. The narrow stream travels into the spinner tube. The spinner tube rotates, redirecting the narrow stream into a continually rotating cone shape: the spin-spray.
