BILLY MATE The Alpha - 40cm
This Billy Mate Alpha Water Pipe features an inline perc chamber, as well as a 6-arm tree percolator.
Together the two create perfectly cooled and diffused smoke, while the built-in splashguard ensures that you never get water in your mouth.
If you are unfamiliar with either of these percolators (either the tree perc or inline perc), you will be happy to know that they are amazing.
The first perc that the smoke passes through is the inline perc. An inline perc is always shaped like a long glass tube. Along the underside of the perc, there are several diffusion slits. Each slit is responsible for generating filtration bubbles, which is why the more slits the merrier.
