How Exhaust Fans Work
Exhaust fans use a motor to spin blades or an impeller at high speed. This action creates a vacuum that draws air from inside your cabinet or enclosure and pushes it outside through vents or ducts. The negative pressure inside the space pulls in fresh air, keeping the environment balanced. You’ll find that exhaust fans often use ducting to direct contaminated air away from sensitive equipment, which is crucial for industrial safety.
Here’s how the mechanism works:
- Motor-driven blades rotate to generate airflow.
- Stale air moves toward the fan and gets expelled outside.
- The pressure difference draws in clean air from outside.
- Continuous operation ensures ongoing stale air removal and temperature control.
Linkwell’s exhaust fans are designed for easy installation and minimal maintenance. Their IP54-rated models handle tough industrial conditions, making them ideal for electrical cabinets and automation panels.

Ventilation Fan vs Exhaust Fan
Airflow Direction
When you compare a ventilation fan vs exhaust fan, the airflow direction stands out as the biggest difference. A ventilation fan pulls fresh air into your cabinet or panel, circulating it to keep the environment cool and safe. This multi-directional airflow helps you maintain improved air quality and supports clean air inside your enclosure. You don’t need external ducting for most ventilation fans, which makes installation easier.
On the other hand, an exhaust fan pushes air out of your space. It creates a unidirectional flow, pulling hot, humid, or contaminated air through the fan and expelling it outside. You usually need ducts for exhaust fans to direct the air away from sensitive equipment. This setup is perfect for removing fumes, moisture, and airborne particles that threaten your electronics.
- Ventilation fans circulate air within the cabinet, promoting air quality improvement.
- Exhaust fans remove stale air, focusing on extraction and expulsion.
- Ventilation fans work as air introducers and circulators.
