CO2 Laser Exhaust Fan Controller

For those that run the AC Infinity fan units this adjust the fan speed automatically. Simply plug this controller into your laser controller and the fan speed cord and let it do the work. This controller will allow the fan to sit at an idol with your laser keeping the noise down and draft out. When the project is started the fan will go full speed until your project is finished. After the laser returns home the set timer will hold the fan at full power to exhaust all remaining smoke left inside the laser. Then return the fan to a low silent speed.  If you already have a Liberty Controls Air Assist, then just connect it with the supplied cable and you're set. This item ia also available for dual fan lasers as well.
