Custom Designed
We install custom-designed Vent Shaft passive louver systems. The pictured system was designed and installed to protect subway tunnel shafts. These shafts vent air as the subway train passes through the tunnel. When flood water rises, the louvers close in sections as needed protecting the critical tunnel infrastructure from flooding. Over 30 units are installed and working as intended. More installations are scheduled.
