This multi-family building on the west side of Chicago was completed in 2017. We used 6″ PVC pipe as the exterior exhaust pipe to minimize noise, decrease potential for system freeze-ups and increase overall efficiency of the system.

In this picture, the Magnehelic manometer is used to monitor negative pressure inside the primary suction point. The oversize suction point was made into the floor to aid in the removal of the aggregate.

This multi-family building on the west side of Chicago was completed in 2017. Pre-mitigation diagnostic testing indicated highly compacted aggregate directly under the concrete slab. When dealing with compacted aggregate with small fines, higher suction series in-lines fans are required. The in-line fans were located on the roof to minimize exposure to noise to the tenants and eliminate tenant complaints. The size of the exhaust pipe was increased to decrease the noise, decrease system freeze-ups and improve the overall efficiency, eliminating additional costly suction points.
