Mirka Dust Extractors

Mirka dust extractors deliver strong, consistent suction, greatly reducing clean-up time while eliminating stray abrasive particles to help ensure better surface finishes and longer abrasive life. They also help avoid health risks associated with airborne dust, with HEPA-certified filtration that removes at least 99.97% of particles as small as 0.3 microns.

Additional components, such as vacuum hoses, are sold separately, so you can build your own customized setup to match the tools you own and the type of work you do.

Here’s an overview of how to use and maintain your extractor.

Set-Up – Power & Suction

Before using the dust extractor, you need to select the proper settings for the power mode and suction.

To operate the extractor so it turns on when you power up your tool, turn the control knob counter clockwise, towards the sander icon. The 10 o’clock position provides maximum suction; as you approach the 6 o’clock position, the suction decreases (Photo 1).

Photo 1 – In auto mode, turn the knob clockwise to increase suction power and counter clockwise to decrease it.

To run the extractor independently, turn the control knob clockwise. The 2 o’clock position is full power; as with auto-mode, the suction diminishes as you near 6 o’clock (Photo 2).

Photo 2- In manual mode, turn the control knob clockwise to decrease suction, counter clockwise to increase it.

To clean up small liquid spills, remove the dust bag and clean the filter before and after wet use.

If you own the push-to-clean version, you can use this feature to give filters a heavier cleaning on demand. First turn on the extractor and cover the inlet fitting or opening of a hose connected to the extractor with your palm. Then press the filter cleaning button three times (Photo 3).

Mirka dust extractors are easy to maintain. Apart from emptying the bag when necessary, the only other thing to pay attention to is the filter.

With regular cleaning, the filter should last a long time if the extractor is only used periodically. However, it’s worth checking the filter once in awhile to ensure it isn’t damaged and the gasket still seals properly. Replacing the filter is a straightforward process. (Photo 4).

Remember to unplug the machine before changing the filter or bag.
