A blowgun directs a jet of compressed air to clear swarf, dust, chips, coolant, and debris from workpieces, machine bores, and surfaces. They are used in machining, fabrication, automotive, and general workshop environments to clean parts during and after machining, clear swarf from tools and fixtures, and dry surfaces before inspection or further processing.

A standard blowgun delivers the full working pressure of the airline through the nozzle. A safety blowgun incorporates a pressure-limiting mechanism that caps the output at a safe level, typically 30 psi (2 bar), to comply with industrial safety regulations. Safety blowguns are required in most commercial and industrial workplaces under EN ISO 4414 and related standards where the air jet could contact skin.

Common nozzle types include standard rigid nozzles for focused jets, flexible nozzles that bend to reach awkward angles, extension nozzles for deep bores and cavities, rubber-tipped nozzles to protect sensitive surfaces, and safety curtain nozzles that diffuse air over a wide area to reduce propelled debris. Most blowgun bodies accept interchangeable nozzles.

Most blowguns are rated to the standard workshop air supply, typically 6 to 10 bar (90 to 150 psi). Always check the maximum operating pressure marked on the blowgun body and do not exceed it. For applications where the air jet could contact skin or eyes, a safety blowgun limiting output to 30 psi (2 bar) is required under most UK and EU industrial safety regulations.

Blowguns connect via a standard quick release coupler. The blowgun body has a BSP-threaded inlet that accepts a male quick release plug. Screw the appropriately sized male plug into the blowgun inlet and connect it to the female socket on the air line. Most blowguns use a 1/4" BSP inlet, but check the product specification. Ensure the coupler profile matches the sockets already in use on your air system.

Standard blowguns deliver full line pressure, which can propel debris at dangerous velocities and cause injury if directed at skin. In industrial and commercial workplaces, safety blowguns are required by regulation in most applications. These limit the output pressure to 30 psi at the nozzle tip, the threshold set by EN ISO 4414. Operators should wear eye protection regardless of blowgun type.
