What size trunk is typically used with the RAMFAN?

The typical trunk size used with the RAMFAN is 10 inches. This size is important because it is designed to optimize airflow and maintain the efficiency of the ventilating system when connected to the fan.

Using a 10-inch trunk allows for the proper balance between flexibility and airflow capacity, ensuring that the RAMFAN operates effectively in smoke and fume removal scenarios. A trunk that is too small would restrict airflow, reducing the overall performance. Conversely, if the trunk were excessively large, it could lead to inefficiencies and potential air loss. Therefore, the 10-inch size is specifically chosen to match the fan's output capabilities, ensuring optimal performance in emergency and ventilation operations.
