Here at Applied, we set the standard in performance and productivity with our unique family of nozzles featuring Tungsten Carbide inserts offering exceptionally good toughness and durability. When choosing a nozzle, first you must take into account that the compressor you have will support the minimum nozzle requirements. The compressor must provide a minimum of 50% more air volume than what anew nozzle would require to develop the correct blasting pressure ensuring persistent good results.
When choosing a nozzle, the nozzle entry throat must be the exact diameter of the blast hose to reduce pressure drop, wear points and excessive internal turbulence. In order to choose a nozzle, the desired blast pattern must be determined first.
A straight bore nozzle will create a tight blast pattern for small jobs such as carving stone, cleaning rails or steps, weld seam cleaning, etc. Venturi bore nozzles create a wide blast pattern and increase abrasive velocity by up to 100%. Double Venturi bore nozzles produce and even larger blasting pattern with minimal abrasive velocity loss. Wide throat nozzles produce the largest blast pattern (60% larger) at higher pressures with lower abrasive use. Angle blast nozzles are used instead of conventional blast nozzles where a user must blast into pipe internals, behind ledges, flanges of beams, inside cavities and the awkward to reach places.
Using the Nozzle Air and Pressure Requirements Chart, a user can identify what bore size the nozzle must be for maximised efficiency. For example, using a 140 CFM compressor at a recommended 100 PSI, the chart shows that a 8mm nozzle would be most suited to maximise productivity.
