Collection: CENTRAX® RADON MITIGATION FAN KIT

Reduce Radon Before It Enters Your Living Space

Active sub-slab depressurization is the recommended mitigation method for full or partial basements, crawl spaces, and cement slabs. A suction pipe extends below the concrete slab and connects to a continuously operating fan. This creates lower pressure beneath the foundation, pulling soil gas into the vent system before it can migrate into occupied living areas.

Our RDN04 and RDN04-3 kits feature a Centrax® centrifugal fan engineered specifically for the high suction and continuous airflow demands of sub-slab depressurization. The unit includes 4” inlet and outlet ports, a sealed housing, automatic thermal overload protection, and anti-vibration couplers to minimize noise transfer across connected PVC piping.

Note: Water damage and damage from obstructions or small animals will void the warranty of internal components. Ensure proper measures are taken to prevent moisture, debris, and wildlife from entering the exhaust pipe.

Key Benefits:

• Centrifugal impeller design builds high suction specifically for sub-slab pressure reduction.
• Enclosed motor rated for continuous use with automatic thermal reset protection.
• Anti-vibration PVC couplers dampen operational noise across connected piping runs.
• Delivers 235 CFM airflow with efficient power usage of 91 Watts and 0.76 Amps.
