How does air circulation and material recycling work in Pekotek's blast rooms?

The short answer is: Air is flow in through the suction channels in the floor. This transports the abrasive material and allows it to be reused in the blasting process.

In this article, we explain our concept in detail and show what makes it so unique.

Air is flow in through the suction channels in the floor (2). Simultaneously, the airflow transports the used abrasive material, which collects in the channels, to the classifier (14). From there, the reusable material is returned to the abrasive tank (19). The dust-laden air is then directed to the filter (13).

The filter is equipped with an automatic compressed air pulse cleaning system that loosens the deposits at the bottom of the filter (16). The fan (15) either blows clean air out of the hall (8) (in summer) or returns 80% of the air (6) to the chamber (in winter)
