In the manual sandblasting cabins, it is the operator himself who operates the abrasive spray gun and determines the angles of attack and the cycle time.
It does so by wearing latex gloves and controlling the process through laminated and tempered glass viewers.
These machines have a self-cleaning filter. In the case of Venturi projection (depression or suction) the filter is incorporated to the machine, being a monoblock. Overpressure blasting equipment is equipped with firing units (blasting machine + cyclone) and filters that are connected to the sandblasting cabin by means of flexible piping.
