The TOOCAA Air Assist Kit ensures that smoke and other particles are blown away, which increases the quality of projects. In addition, it cools the laser module and the air assist protects the lens of the module from contamination, which extends its lifespan. By blowing away the air, the temperature of the surface is reduced, which prevents deformation and discoloration. The air strength can be adjusted between 0 and 28 litres per minute to blow away smoke extra effectively. With a maximum sound level of 40 db, the air assist is quieter than a normal fan.
