5/16 Siphon Blaster Air Jet

The 5/16″ air jet is designed for ALC siphon guns using 13/64″ nozzles. The 5/16″ jet and 13/64″ nozzle bore are matched for the clearance that creates vacuum to draw media. Using this air jet with a different nozzle size changes the clearance and reduces media draw through the siphon gun assembly.

The 5/16″ air jet pairs with 13/64″ nozzles at 7 CFM. The 5/32″ air jet pairs with 5/16″ nozzles at 20 CFM. Each air jet is matched to a specific nozzle bore. Using the 5/32″ jet with a 13/64″ nozzle changes the clearance and affects media draw through the siphon assembly.

Replace the 5/16″ air jet when siphon media draw drops without a pressure change, when blast output becomes inconsistent at standard pressure, or when the jet orifice shows visible wear. A worn air jet reduces the vacuum that drives media draw through the 13/64″ siphon nozzle assembly.

Replace both when both show wear. If only one is worn, replace only that component. A new air jet with a worn 13/64″ nozzle restores vacuum but the worn bore still reduces blast output. A new nozzle with a worn jet leaves vacuum reduced. Both must be serviceable for full siphon performance.

Using an incorrect air jet with a 13/64″ nozzle changes the clearance that drives the siphon vacuum. The 5/16″ jet is matched to the 13/64″ nozzle for the clearance that delivers 7 CFM media draw. A non-matching jet reduces media draw even if the nozzle and air pressure are both correct.
