What will you provide in the entrance door to control air from coming in and out?

• A. Air Curtain
• B. Exhaust Fan
• C. Dehumidifier
• D. Electric Fan

Answer: (A)

An air curtain is designed to create a barrier of air that effectively controls the movement of air between two environments, typically between the exterior and interior of a building. By generating a high-velocity stream of air across the entrance, it prevents outside air, dust, insects, and pollutants from entering while still allowing for free pedestrian access. This technology is particularly useful in commercial buildings where doors are frequently opened and closed, as it helps maintain indoor temperature and air quality without the need for physical barriers. This solution enhances the energy efficiency of the building by minimizing the loss of conditioned air and helps to maintain a comfortable environment for both occupants and visitors. Other options do not specifically serve to create a barrier at entry points – for instance, exhaust fans are used to remove air from a space, dehumidifiers control moisture levels, and electric fans mainly circulate air within a room rather than managing air infiltration.
