We've got the equipment to handle it
Heavy duty suction from the Hypervac H1 gas powered havac system. Including a 35hp positive displacement fan creating negative air pressure preventing dust and debris from entering the building. The 20hp, 2 stage 4 piston compressor, provides the high pressure air needed to operate a variety of agitation tools to ensure a entirely clean system.
