Patent Primary Examiner
A filtration system is used with a pipe repair system, such as a cured-in-place pipe lining system. Before, during, and/or after the repair of the pipe with the pipe lining system, air from inside the pipe is directed into a filtration system. The filtration system removes contaminants, such as VOCs and other harmful gases, particles, and the like, with a filter, and then the filtered air is exhausted from the system. The filter can be a carbon filter or other filter that can remove harmful or hazardous materials and particles from the air prior to exhaust. The air is also sensed to acquire information, such as temperature, pressure, composition, flow, or the like.
