What is the main purpose of a mechanical exhaust system?

The primary function of a mechanical exhaust system is to remove air from spaces. This system plays a crucial role in maintaining indoor air quality by expelling stale air, odors, moisture, and potentially harmful contaminants, thereby promoting a healthier environment.

In areas such as kitchens or bathrooms, exhaust systems efficiently eliminate smoke, steam, and humidity, which can otherwise lead to mold growth and structural damage. By facilitating the removal of unwanted air, the system helps create a balance with fresh air intake, ensuring ventilation standards are met and enhancing overall air circulation within the environment.

While heating and cooling are important functions within HVAC systems, they are not the primary purpose of an exhaust system, which is specifically designed for air removal rather than thermal management.
