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.
