Due to varying sub slab soil conditions and building size, determining the exact negative pressure required for the job has always been a challenge. Not knowing exact sub slab pressure drop characteristic, radon mitigation becomes art not a science.

Pressure Field Extension Diagnostic Kit, or PFEDK, as the name implies is a tool that can help radon mitigators accurately sizing any sub-slab depressurization application up to 4.4” Static. No more guessing or “poking and hoping” that the past experience would work.

Fantech’s PFEDK includes our Rn 4EC fan, LDVI Pressure Sensing Couplings to fit a 4” PVC pipe, digital manometer, app and cross reference materials, all housed in a road-tough, heavy duty Pelican® rolling case.
