Heng's Vortex II Roof Vent Fan Upgrade Kit | 3-Speed with Reverse, 9" Blade, White

When a roof vent fan gets noisy or stops moving air, the Vortex II kit replaces just the fan assembly inside select Heng's vent housings. It runs on 12V DC with three speeds and reverse, so you can pull air out or push it in depending on conditions.

• 9" fan blade upgrade for select Heng's roof vent housings
• 3-speed operation with reverse for intake or exhaust airflow
• Runs on 12V DC power
• Installs without disturbing the existing rooftop seal
• Straightforward installation into a compatible housing

Check that your existing vent housing is a compatible Heng's model before ordering, since this kit is a fan replacement, not a complete vent lid.
