The Power Stream Aerator Head adds oxygen to the incoming water by the use of an inbuilt venturi. This mixes air into the water as it travels along the inlet tube (wand).
The wand comes in two lengths. The short wand reaches down 233mm (9 1/2") and the long wand reached down 380 mm (15") and can easily be removed for cleaning.
The aerator head gets attached to a 19mm (3/4") thru-tank fitting (purchased separately) with a simple hand-tightened nut.
The aerator head can be rotated 360 degrees on the thru-tank fitting, to suit your desired placement. The flow-director right on the end can also be rotated 360 degrees around the wand, to direct water at any angle you want.
