Zehnder Q600 ERV (600m3/h 200Pa) with enthalpy exchanger

Product Part Number

471502026-Special

Product Overview

The Zehnder ComfoAir Q600 with Enthalpy Exchanger is a high-capacity mechanical ventilation with heat recovery (MVHR) unit designed for large residential dwellings and applications with high ventilation demand. With a maximum airflow of 600 m³/h, it delivers powerful, balanced ventilation while recovering both heat and moisture to maintain a healthy and comfortable indoor environment.

The integrated enthalpy heat exchanger enables the transfer of moisture in addition to heat, supporting indoor humidity control and reducing the risk of overly dry air during colder months. Featuring EC motor technology, advanced airflow regulation, and a thermal efficiency of up to 76%, the ComfoAir Q600 combines robust airflow performance with energy-efficient operation.

Designed for maximum installation flexibility, the unit supports wall, floor, ceiling, and roof mounting, with reversible left/right orientation and multiple residential connection options. It is compatible with wired and wireless controls, app-based operation, Modbus integration, and a comprehensive range of sensors including humidity, CO₂, and VOC, making it suitable for demand-controlled and zoned ventilation systems in larger homes.
