Description
The Soler & Palau RCXII12S is a 12″ RCX Series Gravity Vent designed for exhaust and supply (E/S) ventilation applications. Engineered by one of the world’s leading ventilation manufacturers, this gravity-operated vent provides passive backdraft control without the need for motorized damper components — making it an efficient, low-maintenance solution for residential and light commercial HVAC systems.
Product Overview
The RCX Gravity Vent relies on differential air pressure to open and close naturally, allowing conditioned or exhaust air to flow freely while preventing unwanted backdraft infiltration when the system is at rest. The 12″ diameter fits standard round duct configurations and is suitable for both exhaust and supply airstream orientations.
