Product Description:
According to European standards, each person needs 20m3 of fresh air per day. If this standard is not met, people will feel stuffy, dizzy, and nauseous. At the same time, harmful gases released by indoor appliances, gas appliances, smoking, decorative materials, etc., if not discharged in a timely manner, can seriously endanger people's physical health. Relying on intermittent air exchange through windows will inevitably introduce noise, dust, mosquitoes, and other pollutants into the room. If a ventilator is installed on the upper or lower part of the window, natural ventilation can be achieved when the window is closed, and it has functions such as sound insulation, noise reduction, dust prevention, insect prevention, rain prevention, and theft prevention. Even at night, on rainy days, and amidst the hustle and bustle of the city, one can quietly enjoy fresh air. Various specifications of ventilators can achieve a ventilation rate of over 30m3 per meter per hour, which is sufficient to meet the air hygiene standards required by the human body. If an active ventilation system is added, the ventilation volume per meter per hour can reach 75m3.
