Moto Engineering Air Blast.

Air Blast is designed to be used with automatic tool length setters. The stylus of the setter can become covered with chips during normal use. 

When the setter is used to set the next tool, if these chips are not cleaned off, an incorrect length will be measured.

The Air Blast is designed to be used with machines that have a triggered air burst installed into the tool setter MACROS.

Using the supplied air fittings and hardware, simply tap into the triggered air port, install the Air Blast, and aim the nozzle at the setter stylus.
