Fan Nozzle for 40W CO2 Laser Basic Blue Box Chinese K40 Type Fan Nozzle This fan nozzle uses a standard 40mm fan to direct air into a stream, assisting in clearing the laser working area of smoke and particles. It's designed specifically for my machine and has been thoroughly tested on several jobs, with impressive results. To ensure optimal performance, you'll need a high-airflow fan - I used a 40mm fan salvaged from old rackmount server cases. The design allows for easy installation and adjustment to meet your specific needs. EDIT (07-Oct-2019): An updated model is now available, complete with improved design and in-use photos. A lock screw hole has been added, allowing you to secure the nozzle onto the laser head using an M4 bolt.
