What is the primary purpose of installing air curtains at entry points?

The primary purpose of installing air curtains at entry points is to prevent flying insects from entering a building. Air curtains work by creating a barrier of air that prevents pests, like insects, from passing through while still allowing for easy access for people and objects. This barrier is particularly effective in environments such as restaurants, food storage areas, and other facilities where maintaining hygiene is critical.

While energy efficiency is an important benefit of air curtains, as they can also reduce heating and cooling costs by minimizing the air exchange between the inside and outside of a building, the foremost function highlighted in this context relates specifically to pest control. By keeping flying insects out, air curtains help maintain sanitary conditions within establishments, making them an essential feature for businesses that prioritize cleanliness and safety.
