Delta Electronics renovates conventional fresh air & purification technology and launches high-efficiency fresh air products & system, for the increasing requirements of better indoor air quality and for the prevention of serious air pollution due to heavy smogs these years. Delta has technology breakthrough not only in the aspects of PM2.5 purification, energy recovery, and quiet operation, but also in brushless DC motor and consistent power control technology.
Delta Electronics FRESH AIR SYSTEM intakes the outdoor air, and then filters and purifies the air efficiently before delivering air to the indoor space. Meanwhile, the system can exhaust the indoor stale air to the outdoors, achieving the whole-house ventilation. Users can obtain high-quality fresh air, even when the whole room is enclosed and airtight.

Whole-house Ventilation
Delta Fresh Air Systems Bring Nature to Your Home
Air pollution problems are getting worse these years. Facing all the threats from outdoor polluted air as well as indoor air pollutants, we all worry this will cause human health issues.
People spend 80%-90% of the time staying indoors. Without well ventilation design, indoor pollutants will cause enormous harm to human bodies, especially children and senior citizens who are more vulnerable to the contaminants.
Either air purifier or air conditioner with filters could help indoor air circulation. However, without well ventilation, there is no fresh air coming to lower the CO2 levels that harm human bodies.
Delta Fresh Air System, including the Energy Recovery Ventilator, intakes the outdoor fresh air, filters and purifies the air efficiently before delivering air into the indoor space. Besides that, the system can exhaust the indoor stale air to the outdoor environment at the same time, achieving the whole house ventilation. Users can obtain high-quality fresh air, even when the whole room is enclosed and airtight.
