5.2 Installation Steps
- Prepare the Opening: Ensure the wall or window opening is appropriately sized for the 18-inch fan (approximately 21.26" x 21.26").
- Position the Fan: Carefully place the fan into the prepared opening, ensuring it is level and flush with the surface.
- Secure the Fan: Use appropriate fasteners (not included) to securely mount the fan to the wall studs or framing. The fan housing has pre-drilled holes for mounting.
- Connect Power: Plug the pre-installed 5.4ft power cord into a standard 120V AC grounded electrical outlet. No additional wiring is required.
Note: For permanent installations or if extending the power cord, consult a qualified electrician to ensure compliance with local electrical codes.
6. Operation
Operating your VENTISOL exhaust fan is straightforward.
6.1 Turning On/Off
Once plugged in, the fan can be operated by a switch on the power cord (if present) or by controlling the power at the outlet. When the fan is powered on, the gravity shutters will open to allow airflow. When powered off, the shutters will close to prevent dust and humidity entry.

Figure 6.1: Fan operation states. This image shows the fan with shutters open when powered on, facilitating heat and odor ventilation, and shutters closed when powered off, providing protection against dust and humidity.
6.2 Airflow and Performance
The fan provides a powerful 2,500 CFM airflow, effectively removing heat, dust, humidity, and odors from the designated area. Its high-speed operation ensures rapid air exchange.
