The 10 cu ft pot is specifically for multiple operator use. Valving on this pot is the normally closed type. From the Schmidt range this is the Thompson valve. This allows one operator to stop blasting without the whole blast pot depressurizing. It works by cutting the abrasive and air to the pusher-line and the valve. BlastOne stocks a full range of abrasive blasting and corrosion control supplies. We have warehouses across North America. There’s one near you. Ask your Area Manager for a customized solution to your blasting challenges.
