Suction blast cabinets Budget cost. Suction blast cabinets are lower cost than the same sized pressure blast cabinet. Easier maintenance. Have far fewer moving parts and valves than a pressure abrasive blast unit, therefore, more easy maintenance and trouble shooting. Less air and abrasive consumption. A ejection gun (suction abrasive blast gun) has its air demand governed by the abrasive air jet, which is typically half the size of the same blast nozzle diameter. This means that for a given nozzle size, a suction blast cabinet uses a part of the amount of air volume (m³/min) than is required for a pressure blast cabinet, when both units are blasting at the same pressure (Bar). Continuous blasting. Because pressure blast pot are absent in a suction blast cabinet, here is no reason to stop, depressurize the vessel and allow abrasive to refill the pot. In a pressure blast system, the length of continuous blasting time is dictated by the amount of abrasive media the pot will hold at one time. | Pressure blast cabinets Greater abrasive media velocity. A pressure blast cabinet produces greater abrasive particle velocity than a suction blast machine which means faster cleaning of items. Moves more abrasive media. More abrasive particles are moved against the work surface per minute, for a given nozzle size. This translates into greater productivity, particularly on difficult applications. Greater stand-off distance. Because the abrasive particles are moving more faster than in suction abrasive blast gun, the stand-off distance of the blast nozzle from the work surface could been increased, producing a larger blast pattern and translates into greater overall productivity than a suction blast machine. More productive. Pressure blast cabinets are four times as productive as suction blast cabinets. |
