Air Dredge Vacuum - Hurricane Flood Debris Clean Up - Venturi Ejector Pump

Description

Air Dredge vacuum cleaner runs on compressed air. Sucks up debris, water, mud, muck into one end, and blows it forcefully out the other end. Can be used with or without a deliver pipe on the outlet end. Buy 3" hose and 3" pipe locally, as needed.
It works like a very powerful Shop-Vac, but without any need for a tank or canister.
Stainless steel nozzle and main body tube. Comes with Chicago-type twist-lock air hose fitting. No moving parts Requires a large air compressor to power it. 3" OD main body tube fits into 3" ID hose or pipe.
Rapidly clean homes and offices with hose and plastic pipe you obtain locally. Suck up flood debris and blow it into the yard or street to get it out of the building.
This is a high-efficiency ejector/eductor jet pump that uses an engineered air nozzle to create a supersonic jet within the main pipe, which pushes the air along to create suction, vacuum, flow and modest delivery pressure. It works like a Keene gold dredge venturi, except that it is powered by compressed air instead of water. It functions like a medium-pressure blower, but without an impeller or fan.
This is a high volume, medium pressure air mover that can carry water and debris along with the air, without having it pass through a fan or blower. Maximum particle size is 2" diameter. It can basically do the same job as a Shop-Vac, but much, much faster. And, there is no tank. Just blow the debris out of the building into the yard or dumpster..
Consumes 150 CFM at 100 psi, or 225 CFM at 150 psi (maximum allowed pressure)e.
Requires a large compressor, such as a Sullair, Ingersoll-Rand or other brand of diesel-powered screw compressor on a trailer. You can often find these at tool rental yards.
WHERE IT COMES FROM
The Air Dredge is made in USA, in my small machine shop in California. There is no commercial source for the Air Dredge ejector pump. Similar devices are commercially available, and are very expensive, costing several hundred to a thousand of dollars more (try Googling "pneumatic dry material conveyer").
I designed the Air Dredge about 20 years ago, and sold many of them at that time. The key element is the air nozzle, which is not just a stub of pipe. It is a very simple design, but has been engineered to mimic a convergent-divergent rocket engine to provide the highest jet speed at the rated input air volume and pressure. At 150 psi, the air jet is moving at about Mach 2, twice the speed of sound.
