Review on 🔫 FIRSTINFO Extendable Air Flow Nozzle Length: 7.68-11.81 inch (195-300 mm) for 2-Way Air Duster Blow Gun by Tabish Jadhav

This is a powerful professional blowgun. Love it. Variable speed is great. There's a blue dial/button on the back, which is also very sensitive to how hard you pull the trigger (so it's very easy to control airflow). MUCH better than the cheap blowguns you get everywhere. It creates a jet turbine sound from a blue nozzle that appears to use a venturi effect to increase airflow. You can remove it (it's a standard blowgun thread size) and put whatever tip you want on it, but I like the way it is. It's nice to be able to lower the air level just enough to blow the dust off my table saw without filling the air with a cloud of dust.
