Dust control is an integral part of the Festool system and design philosophy. That is why the CT 26 is equipped with tool-triggered auto start functionality so that when you plug your tool into the supplied outlet socket, the vacuum cycles with the tool. This represents greater efficiency in dust extraction, noise reduction, and with less energy consumption versus a constant-on unit. Variable suction force allows you to regulate the suction based on your tasks. A small detail sander may not require the full 137 CFM of this unit, but a router may require it.
