Blasting Equipments

HMA’s smallest closed-circuit tool, the hand-portable Mini Vacuum-Blast goes anywhere and operates on just 90 cfm of air at 90 psi. The operator controls blasting and recovery with a trigger handle. Pulling the trigger just slightly starts the vacuum recovery. Pulling the trigger all the way starts the suction blast system.

The compact conical hopper contains the abrasive and meters it into the blast system. Air rushing through the Mini Vacuum-Blast’s mixing chamber draws the abrasive into the airstream and propels it out the nozzle. The blast head swivels to allow blasting at any angle and the rubber boot traps the dust and abrasive. The vacuum captures the reusable abrasive particles and sends the dust and broken abrasive to the dust bag.

The Mini Vacuum-Blast cleans an area about one inch wide. After blasting, the operator releases the trigger about halfway to stop blasting, but continues vacuuming for two or three seconds to recover any remaining dust and abrasive. Fully releasing the trigger stops the vacuum system. The Mini Vacuum-Blast is designed for use with steel and iron grit. The simple cotton bag traps dust.
