Important Information Regarding Circuit Breaker Electrical Standard

Festool dust extractors are fitted with a circuit breaker for safety when a connected load of 1200 watts is exceeded.
Some tools that draw higher wattage can trigger the circuit breaker and if initiated requires the reset button above the socket to be pushed in and reset.
When requiring to use larger wattage tools with dust extraction it is recommended the tool is operated off a separate outlet and a Bluetooth system can then be used to switch the dust extractor on and off as required.
When using tools it is recommended you always use the correct consumable for best results as even lower wattage tools can trip the circuit breaker if the system isn’t matched to the application. (e.g.: saw blade not matched to material)

    Safe dust removal

    Festool's CTH provides maximum safety in the case of carcinogenic and pathogenic dusts such as lead, cadmium, nickel and zinc chromate.

    High suction power

    Super strong and yet super small, the high power turbine provides considerable higher suction power but takes up very little room.

    Maximum utilisation

    The flat filter design allows the filter bag to unfold easily and expand to use almost 100% of its capacity. Hold more dust in a more compact extractor.

    Safety sealed

    The two layer safety filter bag prevents contact with the harmful dust when disposing of the bag.

    Customise for your needs

    Every extractor can be fitted with add on modules to suit different requirements including air modules, power socket with continuous current and EAA module.
