AQUA-JET VENTURI 40MM KIT

The AQUA - JET Venturi are simple to connect on the inside of the koi pond inlet on the return to the pond, so as the water is pumped back to the koi pond it passes through the Venturi which also draws in air at the same time from the atmosphere as it passes through. These Venturi's have two funnels supplied with the kit a small one and a large one. Depending on the output of the pump one of these is just pushed into the rear of the main body of the venturi. A simple but very effective way of increasing the oxygen levels in your koi pond or pumped filter system. Can be fitted in to a 1½ waste socket Can be fitted in any pumped line. It will not work in a gravity fed line.
