The removal of spent shot-blasting abrasive from the interior of storage tanks, tankers, or box girders prior to painting is catered for by a low-cost grit-recovery system called the Airlift Conveyor, supplied by P. and J. Gehler Ltd, High Wycombe. The unit consists of an air ejector utilising a "parallel" venturi through which compressed air is passed. It is capable of lifting and transportating 2 to 2 1/2 tons of abrasives over 30 m, vertically or horizontally. Compressed-air requirements are only 125 CFM at 80 lb/in2. Total weight of the ejector unit, without the conveyor hose, is less than 14 kilos and prices start at under 300 English Pound. After removal of the bulk of the abrasive, any remaining dust and small particles can be collected by the Alvac Pneumatic Suction Cleaner of which some details are given.
