Air curtains are essential components used alongside air conditioning systems to maintain indoor air quality and temperature. They create an invisible barrier of high-velocity air that prevents warm air, dust, and insects from entering climate-controlled spaces. In the AC manufacturing industry, air curtains help enhance energy efficiency by reducing the load on cooling systems. They are widely installed at entrances of commercial buildings, cold storage units, and clean rooms. Manufacturers design air curtains with durable motors and adjustable airflow to suit various applications. By minimizing temperature fluctuations, air curtains improve occupant comfort and reduce energy costs. Their integration is increasingly popular as industries focus on sustainable and cost-effective cooling solutions.
