Part Number: 140-723
Category: Abrasive Blasting Guns
Type: #4 Blasting Gun – 1/4″ Tungsten Nozzle with 3/32″ Air Jet (12 CFM @ 80 PSI)

The #4 Blasting Gun (Part No. 140-723) is a compact, precision suction-style blast gun engineered for cabinet and bench-top abrasive blasting where durability and control are critical. Featuring a 1/4″ tungsten nozzle paired with a 3/32″ air jet, this configuration delivers efficient blasting performance at a lower air demand of 12 CFM @ 80 PSI, making it ideal for shops with limited compressor capacity or for extended run times.

Tungsten nozzles provide significantly longer service life compared to ceramic, especially when used with aggressive or angular media. Additionally, the air jet and suction head are heat treated to Rockwell Hardness (HRC) 58–62, ensuring exceptional wear resistance and consistent performance in abrasive environments.
