This professional M-class dust extractor has a high performance motor and turbine, which creates 250 mbar vacuum and 4500 l/min air flow. The AutoStart function increases the lifetime of the motor and reduces noise. Flat top with space for storage and large wheels for better maneuverability. Auto-filter cleaning for convenience and consistent performance, as well as an air-flow sensor which indicates when air flow falls below optimal. Hose and cable storage for more comfortable transportation. A fleece dust bag is also included. The dust extractor should always be used with Mirka antistatic hoses (not included).The 1230 dust extractor range is equipped with a high-performance 1200 W motor and a 1-stage turbine that creates 250 mbar suction with an airflow of 4500 l/min. The new 1230 dust extractors include the auto-start function. As the dust extractor only runs when the power tool is in use, thanks to the auto start function, there is less noise and at the same time the dust extractor gains a longer lifetime. Bigger wheels significantly improve maneuverability on uneven floor surfaces. Another advantage is that the filter is easy to reach through a separate opening in the back without removing the upper part.
