How to Choose a Swamp Cooler Air Duct for Your Setup

A duct must suit the cooler outlet and airflow it is designed to move. Check dimensions and installation limits in the model manual.

A swamp cooler air duct search may mean a replacement duct, a ducted evaporative system, or a way to direct a portable unit outlet. These setups differ, and a generic duct may restrict airflow. Check the cooler manual for outlet dimensions and permitted duct runs. Ventilation and a path for moist air to leave matter as much as the supply duct.

Common questions

Questions before you buy

Can I connect a duct to a portable swamp cooler?

Only if its manufacturer permits it and the outlet is designed for a duct. Added resistance may reduce airflow, so follow the model manual.

How do I size a swamp cooler duct?

Use manufacturer outlet dimensions and airflow requirements. Duct length and bends affect resistance.

Does an evaporative cooler need an exhaust vent?

Yes. Cooled air needs a route through the space and out, such as an open window or door.

Can flexible duct be used with a swamp cooler?

Only when permitted by the system design. Check diameter and support requirements.
