MENRED G4 floor-mounted vertical ERV fresh air system is a cabinet-style energy recovery ventilation unit specially developed for finished houses, old house renovation and mid-to-high-end residential projects that cannot carry out ceiling concealed construction. Adopting independent vertical floor standing layout, it eliminates the need for ceiling disassembly and embedded pipeline construction, greatly shortening the renovation construction cycle and perfectly solving the fresh air upgrading demand of completed decoration spaces.

Equipped with original Germany ebmpapst DC fan as the core air supply component, the unit runs stably with ultra-low rated power of only 130W, controlling running noise at merely 37dB(A) to avoid noise interference to family daily rest and office work. The supply fan static pressure reaches 100Pa and exhaust static pressure is 50Pa, which supports long-distance multi-room duct layout to realize uniform fresh air supply for each separated room. Built-in high-precision integrated air quality sensors can real-time monitor indoor PM2.5, CO₂, temperature and humidity data, automatically adjust fan speed according to air pollution level to realize unattended intelligent on-demand ventilation.

This floor ventilator adopts imported Japan Toray filter material to build G4 primary filter + HEPA high-efficiency composite purification system, achieving 99.2% ultra-high PM2.5 interception efficiency to block outdoor haze, pollen, fine dust and floating allergens, while efficiently adsorb formaldehyde, benzene and other volatile harmful substances left after interior decoration. The built-in high-efficiency total heat exchanger fully recycles temperature and humidity energy contained in exhausted indoor waste air, reaching 71% heating heat recovery efficiency and 61% cooling recovery efficiency, which effectively reduces extra energy loss of air conditioning and heating equipment caused by fresh air temperature difference, significantly cutting users’ long-term household operation electricity expenditure.

Powered by standard 220V~50Hz power supply, G4 owns rated airflow of 350m³/h and maximum airflow up to 480m³/h, matching applicable indoor area up to 200 square meters, widely suitable for large duplex apartments, villas, finished homestays and independent office ventilation renovation projects. Its fresh air ratio hits 99%, continuously input high-proportion pure fresh outdoor oxygen into closed indoor space, thoroughly solving indoor hypoxia, stuffiness, peculiar smell and excessive carbon dioxide concentration caused by long-time window closing.

The vertical cabinet body dimension is 1360×630×400mm with net weight of 65Kgs, stable vertical base structure ensures safe floor placement without wall fixing operation. Customers can optionally configure intelligent touch screen controller and complete matched ductwork system, supporting Tuya APP WIFI remote monitoring, parameter setting and timing operation for remote intelligent control. All MENRED G4 series pass strict multi-process factory aging inspection and international CE, UKCA safety certifications. Stable monthly production capacity supports OEM customized logo and packaging service for global fresh air distributors, interior decoration companies and homestay engineering contractors.
