Guardair's XtraThrust® Series provides all the benefits of the Long John® Series but with 40% more power. Ideal for the toughest applications and to move the heaviest debris, the XtraThrust nozzle generates over 300% more thrust compared to conventional air guns, yet limits static pressure to less than 30 psi should the tip become blocked. Ergonomic, Classic pistol grip-style handle provides maximum user comfort.
