Your Benchmark compact blow gun has a compact format, with its streamlined design that fits comfortably in your hand. Its cushioned lever is easy to operate with your thumb. The built-in large hanging hook of your blow gun allows you to store it quickly & safely near your workstation. Your blow gun comes with two interchangeable nozzles, depending on the type of projects that needs to be done. The first one is a safe nozzle (OSHA & Canadian health & safety agencies approved), which prevents nozzle clogging on contact with your skin or an object, as air will escape through the openings on both sides of the blow gun & the static pressure will remain below 30 PSI, for safe usage. Also, the anti-scratch rubber nozzle will allow you to clean effectively, without scratching delicate surfaces or delicate projects.
