The CarryVac 2 P150 AST is a small, lightweight, portable extraction unit designed to be carried to the working area. Connected to a welding torch or to an extraction nozzle, the CarryVac 2 unit extracts the fume directly at source. The polluted air is filtered and captured in a hygienically-packed filter. The CarryVac 2 is equipped with a filter indicator, which shows when the filter must be replaced. It is ideal for maintenance welding, low and medium-duty cycle. The filter capacity is approximately 200kg of solid wire or twelve 15kg spools. The CarryVac 2 P150 AST is equipped with an automatic start/stop function, which increases the service life of each filter and of the unit itself.
