MENRED G7 wall-mounted vertical ERV fresh air system is a space-saving wall-hung energy recovery ventilation unit customized for fully decorated villas and large apartments that cannot implement ceiling concealed pipeline construction. It adopts vertical wall-mounted installation design without any ceiling disassembly or pre-buried construction, perfectly solving the fresh air renovation pain point of finished houses and old buildings, and matching various indoor decoration styles.

Equipped with original Germany ebmpapst DC fan as core air supply component, the unit runs stably with ultra-low rated power of only 130W, controlling operating noise at 39dB(A) to avoid sound interference to daily rest and office work. Its supply fan static pressure reaches 80Pa and exhaust fan static pressure is 50Pa, which supports long-distance multi-room duct layout to send uniform fresh air to every separated room. Built-in integrated high-precision air quality sensors can real-time detect indoor PM2.5, CO₂, temperature and humidity data, automatically adjust fan speed according to air pollution concentration to realize unattended intelligent on-demand ventilation.

This wall-mounted ventilator is fitted with imported Japan Toray filter material to build G4 primary filter + HEPA high-efficiency composite purification structure, achieving 98% 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 73% heating heat recovery efficiency and 65.5% cooling recovery efficiency, which effectively reduces extra energy loss of air conditioning and heating equipment caused by fresh air temperature difference, significantly cutting household long-term electricity expenditure.

Powered by standard 220V~50Hz power supply, G7 owns rated airflow of 350m³/h and maximum airflow up to 450m³/h, matching applicable indoor area up to 200 square meters, widely suitable for large duplex apartments, villas, boutique homestays and independent office ventilation renovation projects. Its fresh air ratio hits 98.2%, 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 wall-hung body dimension is 940×630×405mm with net weight of 57Kgs, lightweight structure simplifies wall fixing installation and shortens on-site construction period greatly. 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 G7 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.
