These Safety Air Nozzles are adjustable, making them suitable for a wide variety of blowoff applications. The design allows you to “tune in” the force and flow to the application requirements, thereby minimizing air consumption. A micrometer-like dial indicates the gap setting. A set screw in the end can be tightened so the air nozzle holds the setting. The Model 1009SS Stainless Steel Adjustable Nozzle is ideal for high temperature, food processing and corrosive applications.
