The Radon Vac™
provides the first effective and affordable way to
reduce radon levels in existing homes. The unique system
consists of a plug-in fan, exterior hood and
installer-purchased PVC pipe. Because the Radon Vac side
wall system evacuates through the basement side wall,
homeowners can avoid having PVC pipe run vertically
through living areas or outside of their homes to the
roof line.
The Radon Vac fan is engineered to
reduce radon across a variety of sub-slab soil types
(dirt, gravel, etc.). It features a sealed, galvanized
housing and a PSC permanently lubricated, quiet, low
watt motor. Unlike traditional radon fans the motor is
not exposed to air stream moisture. |

The
corrosion-proof Radon Vac Variable Aspiration Control
Hood dilutes the radon gas with fresh outdoor air as it
exits the hood and safely propels it away from the
structure. Airflow velocity is easily adjustable at the
hood to accommodate the length of pipe run and whether
the radon is being drawn from a sump pit or below the
basement floor.
Installation of the Radon Vac
system requires a four inch hole through the home’s
basement rim joist and exterior finish, plus enough
three inch PVC pipe to run from the radon extraction
point to the Vac hood. The fan is typically installed
between floor joists. A rubber isolating mounting
bracket eliminates vibration transfer and rotates 360
degrees to accommodate any orientation.
Radon Vac™ Case
Study
See
the Radon VAC™
Hood - Smoke Demonstration Video |
Radon is a national environmental health problem.
Elevated radon levels have been discovered in virtually
every state.
The EPA estimates that as many as 8 million
homes throughout the country have elevated levels of
radon. State surveys to date show that 1 out of 5 homes
have elevated radon levels.

Dilution is the Solution
The corrosion–proof hood infuses outdoor air
into the exhaust to dilute it. This mixture
is further diluted as it is propelled away
from your home in a jet of air. |
Perfect for
Existing Home Retrofits
Often radon issues are
found in finished homes making the long pipe
runs of typical systems costly and
impractical. Side wall venting with the
Radon VAC requires only a 4” hole through
the basement rim joist and a fraction of the
PVC. |
Quiet,
Efficient Operation
PSC permanently
lubricated ball bearing motor is not exposed
to moisture in the air stream. Uses only 50 watts. Engineered to reduce radon across a
variety of sub-slab soil types (dirt, sand,
gravel, etc.). Features 6’ power cord. |
 |
 |
 |
Variable Aspiration Control
Easily adjust the discharge hood to match
your system needs. This allows the Radon VAC
to operate in sub-slab or sump pit
installations and with different pipe runs
while always producing a strong stream of
diluted exhaust. |
Easy Installation
Both
fan and hood directly connect to 3” PVC—no
rubber couplers needed as with other fans.
Rubber isolated mounting bracket eliminates
vibration transfer and rotates 360° to
accommodate any orientation. Mount
vertically or horizontally.
|
Sealed Housing for Safety
Custom-fitted gaskets throughout the fan
prevent radon gas leakage. Features heavy
duty galvanized steel housing and
powerful backward inclined steel impeller. |

Tjernlund’s Mitigation
System Alarm alerts the
homeowner of a fan failure or
other issues. Ideal for remotely
located systems that may not be
inspected regularly. Audible and
visual alarms instantly alert
homeowners when a lack of system
pressure is detected. Can be
wall or pipe mounted. Includes
cord, hardware and tubing.
Compatible with any model fan or
subslab depressurization system
layout. |
Diluting radon concentrations with
outdoor air is an effective and affordable
way to decrease radon exposure in homes.
Tjernlund Radon Ventilation Fans are the
effective, affordable way to reduce radon in
homes with moderate (10 pCi/l or less) radon
levels.*
RX2 Ventilator
For Basements and Sealed Crawl
Spaces
The RX2 Radon Ventilator includes 2
reversible fans that can be set to
exhaust radon, supply fresh air, or
positioned with one fan in each
direction for a balanced air
exchange. At 220 CFM, the RX2
ventilates a 20’ x 40’ x 8’ basement
twice per hour and uses only 32
watts.
Needs only a 5” x 12”
opening through the rim joist or
outside wall. Comes with 6’ power
cords and exhaust hood. Run it
continuously or with a plug-in
timer. Also helps reduce basement
humidity.

RV2 Ventilator
For Ventilated Crawl Spaces
The RV2 Radon
Ventilator exhausts radon and other
harmful soil gases and allows fresh
outdoor air to replace them. At 220
CFM, the RV2 ventilates a 20’ x 40’
x 3’ crawl space over 5 times per
hour while using only 32 watts.
Simply mount the unit against a vent
opening with the included hardware
and plug it in. For even greater
results multiple units can be
installed. Run it continuously or
with a plug-in timer. Also helps
reduce crawl space humidity.
