Broan AI Series B230H75RS Heat Recovery Ventilator (HRV), 231 CFM, Side Ports

Maximum Heat Recovery for Very Large Homes — Side Port Design for Shallow Installations

The Broan AI Series B230H75RS 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 in colder climates, the B230H75RS delivers up to 60% energy savings while effortlessly moving maximum air volume. Built on an ultra-durable, leak-free platform with side-positioned 6-inch ports, it's ideal for wall or ceiling mount layouts where vertical height is restricted. Setup, real-time balancing data, and diagnostics are all managed directly through the built-in LCD screen.
