NORTHLAND GARDENS ON-LINE
VENTURI ASSEMBLY (small)
For use with pump model 9.5 thru 18
Used in conjunction with an air fractionating impeller to provide air intake and expulsion at the output of your pump in the form of tiny bubbles. Air is pulled into the venturi through attached intake tubing which is secured outside of the water. The movement of the water pulls the air into the impeller housing and 'chops' it up using the specially designed air fractionating impeller.
