The MENRED G4 is a floor-standing energy recovery ventilator with a rated airflow of 350 m³/h and a maximum airflow of 480 m³/h. Its polymer membrane enthalpy exchanger recovers both heat and moisture. The unit uses a bidirectional DC inverter fan and G4 HEPA filtration, with a listed filtration efficiency of 99.2%. A built-in air quality sensor and ductwork-compatible static pressure specifications support residential ventilation projects.
The G4 combines fresh air supply and exhaust with enthalpy heat recovery and multi-stage filtration in a floor-standing unit. Its polymer membrane exchanger recovers heat and moisture from exhaust air. The listed heating efficiency is 71%, and the cooling efficiency is 61%. Floor-standing installation avoids ceiling-space limitations and provides access for operation and maintenance.
