The Model 75U™ is the perfect tool for cleaning inaccessible and hard to reach areas. Long John Air Guns are used for blowing floor debris into piles, cleaning masonry forms, tanks, ovens, large molds, pipelines, rafters as well as machinery and storage areas. Pistol style grip and standard aluminum extension make Long Johns light in weight and easy to handle. Long Johns deliver full plant air pressure to the cleaning job at hand through a high efficiency aluminum venturi nozzle. This nozzle boosts the available thrust up to 250% and at the same time limits the static pressure to less than 30 psi if the tip is blocked. The Model 75LJ™ has a 1/4" NPT (female) inlet and a maximum ...
Main air flow speeds up as it passes through the nozzle drawing in ambient air through the two side ports. The increased velocity and increased volume of air exiting the nozzle boosts the available thrust up to 250%.
Should the nozzle tip become blocked, all of the main air flow exits through the side ports. Under these conditions static pressure at the nozzle tip is held to less than 30 psi, there by satisfying OSHA safety standards.
