Blast Room Dust Collectors

All Airblast rooms are ventilated at a through rate of 40 to 50 ft/min. This can be up to twice as much as the rate offered by many of our competitors. It is our experience that these speeds are the ideal solution when trying to suspend a particle of abrasive dust along the length of a blast room without grit carry over to the dust extraction.

Generally for applications of up to 3000cfm, we would recommend a shaker filter purely on the grounds of economics. Thereafter our reverse jet cartridge unit would be recommended.

Our Dust Extraction Process. Powered by the specified fan the room can be efficiently extracted of airborne dust particles to leave the operator with minimal visual hindrance whilst blasting. This is achieved by locating the air inlets on the roof at the front of the blast room and extracting the air and dust at low level at the rear of the blast room. Spanning the inlets and extraction outlet across the width of the room helps achieve smooth laminar flow through the room. This helps eliminate the number of dead and turbulent areas in which dust may be held. Each set of air inlets is specifically designed for each facility. Introducing air into the room and extracting air at certain velocity (governed by physical dimensions of inlet and extraction openings) has proven to be the most effective at providing sufficient flow to carry dust particles whilst remaining laminar and uniform over the length of the room.
