Abstract: An upblast rain cap may have an inverted bottom cone joined to a top cap. The wall of the bottom cone is at an angle of less than 45 degrees with respect to a vertical axis. The joined cone and cap are held above a lower support coupler by a spar. The height of the bottom cone above the support coupler forms a side discharge area. The coupler attaches to the top of a vertical conveyance pipe through which exhaust air flows. A gutter is formed around the edge of the top cap. The gutter has a vertical opening that is aligned with the top of the spar. When rain falls, water flows over the top cap to the gutter, through the opening in the gutter, down the outside edge of the spar and down the outside of the support coupler.

Abstract: A vapor management system includes a monitoring service system configured to communicate one or more system parameters with at least one vapor mitigation system. The monitoring service system is further configured to generate a user interface. The user interface is configured to display and permit adjustment of the one or more system parameters.

Abstract: A vapor mitigation system includes at least one vacuum pipe configured to collect vapors beneath a floor of a building, and a blower coupled to the at least one vacuum pipe. The blower is configured to create a vacuum under the floor of the building. The vapor mitigation system includes a controller configured to control a speed of the blower. The controller adjusts the speed of the blower in response to a level of vacuum created under the floor of the building.
