Heat Recovery Ventilation Unit – Efficiency and Comfort

The AirPack4 300h Energy++ ventilation unit is an advanced solution ensuring optimal air quality in your home. With a capacity of up to 310 m³/h, this device efficiently recovers heat from exhaust air, reducing energy losses and lowering heating costs. As a result, your home will always enjoy fresh, healthy air without unnecessary strain on your household budget.

Technology for Demanding Users – Automation and Innovative Solutions

The AirPack4 300h Energy++ is not just a heat recovery unit—it’s an intelligent ventilation system. Equipped with the CF2 automatic airflow control module and the AFC filter condition monitoring module, it ensures balanced ventilation and optimal energy use. The CF2 system continuously adjusts fan speeds to maintain perfect balance between supply and exhaust air, maximizing heat recovery. Meanwhile, AFC monitors filter usage and alerts you when replacement is needed—no more guessing or unnecessary expenses. Additionally, the unit features the FPXptc anti-freeze system with a smoothly regulated PTC heater, protecting the heat exchanger from freezing even at low temperatures.

Design and Durability – Thoughtful Solutions for Installers and Users

The AirPack4 300h Energy++ heat recovery unit stands out with its robust construction and high manufacturing quality. The FullShell casing eliminates thermal bridges, providing excellent thermal insulation. The ability to install the unit in unheated spaces (down to -15°C) offers great flexibility in layout planning. Standard features include high-efficiency CleanPad Pure filters with increased dust-holding capacity and a fully insulated 100% bypass, allowing the delivery of fresh air without heat recovery during warmer days. Modbus RTU communication enables integration with smart home systems, and the option to connect additional sensors (humidity, air quality) or a heating cable for freeze protection further enhances functionality. The counterflow polystyrene heat exchanger ensures high heat recovery efficiency of up to 95%.
