HIgh pressure two-way bass positive pressure ventilation fans

1.Total heat type 2.High heat recovery efficiency 3.Two-way ventilation 4.High external static pressure

Energy saving principle of  HIgh pressure two-way bass positive pressure ventilation fans

Features of High static pressure heat and energy recovery ventilator (HRV&ERV) - new series

1. Effective ventilation2. High efficient energy recovery, over 70%3. Perfect silence design4. Air filtration and purification5. High airproof feature and easy maintenance6. Higher static pressure for more applications Working principle of Holtop  Ceiling mount  bypass  heat recovery domestic ventilation system  Holtop heat & energy recovery ventilator can expel the stale air indoor out of room, meanwhile supplying the fresh air outside into the room, by using the advanced heat/energy recovering technology, the energy can exchange taking advantage of the difference of the temperature and humidity between indoor and outdoor air. By this means, it can not only smooth away the problem of indoor pollution, but also saving energy. Technical parameters
