Factory recommended RPM is 1800 5/8' keyway shaft. The T80 compressors are recommended for shallow diving conditions including dredging. It connects easily to dredge motor to supply hookah breathing system.

In a good creek power jet, In puddle jumping use the suction nozzle. The T-80 is a medium-duty oilless diaphragm compressor with pressure relief valve. The idea is that if you are using a jet flare and should you pop the hose out of the water and lose prime the pressure jet may blast material out of the box, find the angle in which the jet blows over the sluice should somthing bad like that happen. This may be different than yours, I'm not sure if you have a crashbox or a jet flare. The jet inlet position doesn't matter too much on my dredge as I still use the old crashbox style header. The jet log will get better gas mileage than a suction nozzle and provide better suction should you keep it floating on the pontoons.

Figure out what rocks to throw away and not hog the nozzle and you will do well. The nozzle restriction will rob your production, fill with small rocks and reduce the flow over the box, the gravels compact, clear the nozzle, and your boxes scour.

Don't put any kind of restriction on the nozzle! It's all bad! Get a snorkel and mask and look what is going up the nozzle.
