Abstract

Radon Removal System comprised of an inline suction fan with “y” type fitting below it. The “y” type fitting is attached to a mounting flange that is positioned over a 4 inch hole in the sump cover or other depressurization port allowing the suction fan to draw air containing radon gas or other contaminants from drain tile(s) having fluid communication with the sump basin. The side inlet of “y” fitting draws exterior air from a flexible or solid PVC pipe located 3 or more feet from the discharge point. The suction fan draws exterior air into the side inlet of “y” fitting and dilutes the radon gas drawn into the lower opening of “y” fitting. The suction fan simultaneously dilutes the contaminated air with clean exterior air before being pumped out of outlet port. The expelled air is discharged into the outside atmosphere where it is further diluted to safe levels posing no health risk. With this system, it is no longer necessary to route the discharge pipe to the highest eve of the roof. The expelled air is sufficiently diluted by mixing with clean exterior air before it is discharged through the band-board opening on the side of the house. This diluted mixture is further diluted upon discharge into the exterior atmosphere posing no health risk. With the availability of this invention and its lower cost, it is hoped that more people can benefit from reduced radon levels in their home and optimally save lives.

Claims

1. A radon removal system that simultaneously dilutes radon gas and/or other contaminants with fresh outside air before exhausting safely to the exterior atmosphere. Because the discharge air has been conditioned, it can be exhausted anyplace on the side of a house structure where it immediately dilutes again as it mixes with the atmosphere;

posing no health risks. As such, it is no longer necessary to discharge through long vertical pipes to the roof edge.

2. The radon removal system as described above is not limited to using just the sump cover as a depressurization port. Other acceptable and recommended ports are through the concrete floor (sub-slab depressurization), through inlet port of sub-membrane cover (crawl-space), connecting into a drain tile, (drain-tile depressurization), or any other means of creating a vacuum to pull radon gas or other contaminants from soil under, next to, or around a structure that contains radon gas or other contaminants. The radon removal system will safely dilute the radon gas or other contaminants regardless of the location or type of depressurization port.
