For ease of flow channel is arranged inside the device, in order to reduce the overall volume of fresh air ventilator with a cross-flow, static plate heat exchanger. Namely: the direction perpendicular movement of hot and cold gas, which belong to the convective heat transfer properties of the turbulent flow within the boundary layer. Therefore, sufficient heat exchange can achieve higher energy efficiency. New wind power part ventilator uses a high efficiency, lower noise fan. The filtered, purified and heat exchange process mandatory outdoor fresh air into the room, while the filtered indoor harmful gas purification and heat exchange process after mandatory exhausted to the outside. Features: Metal shell brand new wind ventilators, body pasted total heat insulation protective layer of new wind ventilators, with good insulation, sound insulation slim compact chassis design, structure, applicable to space restrictions in effect places the filter effective mosquitoes, pollen, dust and other stationary block out efficient exchange core, more than 70% energy recovery ventilators new wind, energy-efficient dual-seat hanging, easy to install vertical wind ventilators new, optional floor-to-ceiling Ceiling with a bypass function, effectively extending filter life, more energy efficient external rotor motor with thermal protection device automatically super fresh air ventilator works | Chenyu factory outlets (certified) | Jinnan District of fresh air ventilator by Wu Cheng Yu Chen Air Conditioning Equipment Limited.
