Lomanco® Standard Power Vents are designed for quiet operation and high volume air removal.

Lomanco offers two styles of electric power vents- the Lomancool™ 2000and the Add-A-Vent 1800. The 2000 is a roof mount power vent and the 1800 is designed to be mounted behind an existing vent to add powered ventilation to a gable.

Common Features

Lomanco® Power Vents are made of all aluminum construction. Other common features include a 5 year limited warranty, balanced fan blades for quiet operation, and an American made motor. An optional humidistat is available for both the 2000 and the 1800. The Lomancool™ 2000TH comes equipped with an adjustable thermostat/humidistat combo control to accommodate individual attic humidity levels.

The Lomancool™ 2000 and Lomancool™ 2000TH are also available in copper.

Lomanco® Power Vents are equipped with an adjustable thermostat that features a “push to test” button that allows homeowners to make sure the unit is operating properly.
