Abstract

This apparatus protects a radon fan from damage due to falling water, ice, critters and debris and is installed above the radon fan and protects the fan in several ways.

It is installed just above the radon fan, thus taking advantage of warm “Earth Temperature” air to reduce ice build-up.

Its screen replaces the critter screen often installed at the top of the exhaust pipe where ice is formed. The screen additionally prevents ice and debris from falling into the fan.

The water bypass catches back-flowing water and directs it around the fan.

The access port serves as an opening for testing, observations and cleaning of any debris that is collected by the screen and the access port is sealed with a removable plug. This apparatus protects and extends the life of a radon fan and is made part of the radon mitigation system.

Claims

1. An apparatus for preventing destructive objects and fluids from entering a radon fan.

2. The apparatus of claim 1 wherein device prevents water, debris, critters and ice from entering a radon fan when installed as a radon mitigation system.

3. The apparatus of claim 2 further including a housing comprising means to prevent objects from entering a radon fan when installed as in a radon mitigation system.

4. The apparatus of claim 3 further including air passage through the housing interior passageway.

5. The housing of claim 3 further including diversion means to catch water and redirect same water to exit the housing.

6. The housing of claim 3 further including filtering means to prevent debris larger then screen openings from entering the radon fan.

7. The filtering means of claim 5 further including openings to allow air passage.

8. The housing of claim 3 further including filtering means to prevent critters from entering the radon fan.

9. The housing of claim 3 further including filtering means to prevent ice from entering the radon fan.

10. The housing of claim 3 further including filtering means to allow radon mitigation system analysis.

11. The housing of claim 3 further including hollow pipe with angled bends open at two ends.

12. The housing of claim 10 further including plumbing pipe elbow with straight or angled bends.

13. The housing of claim 4 further including drain opening to allow channeled water to exit housing to bypass radon fan.

14. The housing of claim 4 further including conduit to channel water from the housing drain opening to bypass the radon fan and terminate down-stream of the radon fan.

15. The diversion of claim 4 further including water channeling means within housing to direct same water out through housing drain opening.

16. The housing of claim 3 further including access opening to remove debris or critters that were prevented by filter from entering the radon fan.

17. The housing of claim 3 further including a containment area holding accumulated debris and critters that do not pass through filtering.

18. The access opening of claim 11 further including removable closure device to seal access opening.
