Broan AI Series B230H75RT Heat Recovery Ventilator (HRV), 230 CFM, Top Ports

Maximum Heat Recovery for Very Large Homes — Built for Cold Climates

The Broan AI Series B230H75RT Heat Recovery Ventilator (HRV) is a premium, high-capacity fresh air system engineered for very large homes or light commercial applications in colder climates where sensible heat recovery — not moisture recovery — is the priority. Powered by Broan's exclusive VIRTUO™ Air Technology, this unit continuously monitors changing indoor and outdoor conditions to automatically balance airflow and deliver fresh, filtered air throughout the building — no manual adjustments required.

Equipped with Broan's most powerful high-efficiency PMSM ECM fan motors and a heavy-duty, impact-resistant polypropylene crossflow core optimized for superior sensible heat exchange, the B230H75RT delivers up to 60% energy savings while effortlessly moving maximum air volume. Built on an ultra-durable, leak-free platform with top-positioned 6-inch ports for maximum performance and a minimal vertical footprint. Setup, real-time balancing data, and diagnostics are all managed directly through the built-in LCD screen.
