Air curtains create an invisible air stream across an open doorway to reduce air exchange between two spaces. In this guide, we’ll cover the basics of how air curtains work, their main benefits, common applications, and the different types available. What Is an Air Curtain? An air curtain, also called an air door, is

The heat recovery ventilator is at risk of frosting in cold climates, which leads to reduced air supply, decreased heat recovery efficiency, and even equipment shutdown. High-quality HRVs employ anti-freezing protection measures. This article focuses on explaining the common anti-freezing methods and the factors to consider when selecting them. Why

The entrance of a commercial building is the main channel for air exchange between the indoor and outdoor environments. Frequent opening of doors can lead to the leakage of air-conditioned air, while external heat, cold air, dust, and insects can enter the building, increasing the load of the HVAC system

Traditional inline fans have been widely used because of simple structure and lower cost.But HVAC systems require more flexible airflow control, lower energy consumption and better integration with smart building systems.EC inline fans are gaining attention among HVAC designers, contractors and ventilation brands. HVAC Systems are Moving Away From Fixed-Speed

Traditional bathroom exhaust fans cannot automatically respond to changing humidity levels. The ventilation performance relies on user operation, which may result in excess moisture, condensation, and poor indoor air quality. However, you can use humidity sensor exhaust fans with automatic control to solve these issues. But why does automatic humidity control
