About Ashtead Technology 10in Air Lift Dredge
This Air Lift Dredge system is designed for effective excavation of seabed sand, gravel, clay and rocks up to 205mm in diameter, in water up to 110 MSW.
The system has no exposed pipe work, delivering the water and air requirements internally which limits any snagging and hose damage. High flow water is supplied to the suction head to lower the density of the material to be dredged. Adjustable jetting nozzles can be moved to deliver horizontal, vertical or 45-degree jetting depending on the project requirements. High volume compressed air is forced in to the 10in pipe work creating a high rate suction force caused by the pressure differential ensuring loosened debris is ejected safely through the exhaust.
The 10in airlift dredge is to be used with a high volume water pump, lift pump, umbilical reel and air compressor only.
