Description

Versatile Fit & Installation

How Your Dranjer J Series Works
J Series have a ball valve that floats, allowing for high flows through the unit.
When the flow stops the valve closes and radon gas can no longer flow up through the floor drain or sump cover. Effectively reducing radon levels in the dwelling.
Dranjer products are engineered and laboratory and field tested. Dranjers are often installed association with an ASD system but may be the only action you need to reduce your radon levels.
