The ATSD(X) range comprises of Tungsten Carbide lined long venturi nozzles with Aluminum Jackets. Tungsten  Carbide is the liner aterial of choice for the majority of contractors due to long life and impact resistance -  the Aluminum Jacket adds to the rugged character of the nozzle. Long venturi nozzles are used in standard applications in which the blaster operates at a distance of more than 30 cm (or 12”)
from the surface. The ATSD nozzle has a 25 mm (1”) inlet and the ATJDX has a 32 mm (1¼”) inlet - both are available with a standard large thread (/50) or fine thread. Airblast high velocity long venturi style nozzles have been designed to maximize blast cleaning rates and provide uniform abrasive distribution. The venturi design accelerates the air / abrasive mix as it exits the nozzle providing additional momentum – this can increase productivity and reduce abrasive consumption by up to 40% when compared with straight bore nozzles.
