Portable Ventilation Duct Selection for Tunnels and Confined Spaces
Select portable duct diameter, length, suspension and coupling details around the fan and the temporary work environment.

Size the duct with the fan
The duct diameter, deployed length, bends and couplings all add resistance. Confirm the fan performance at the required airflow rather than using only the fan outlet diameter as the selection basis.
Choose positive or negative pressure construction
Fresh-air supply and extraction duties place different loads on the duct wall. State the airflow direction and expected pressure so an appropriate construction can be selected.
Plan handling and suspension
Temporary duct is repeatedly moved, folded and hung. Ask for suitable hanging points, coupling type and section length to make installation practical for the work crew.
