Circular ventilation louvers offer an effective solution for improving airflow and reducing heat or moisture buildup in residential and commercial spaces.
These louvers provide consistent airflow without disturbing the existing structure and help prevent weather damage and insect intrusion with their built-in protective screening.

They are an excellent choice for ventilating kitchen cabinets, home electronics enclosures, garages, workshops, and other enclosed spaces where efficient airflow is critical.

They press easily into place, saving time for contractors, builders, and DIY homeowners.

Made from high-quality polypropylene with UV inhibitors, these louvers resist weather conditions and protect against long-term environmental exposure.
Their durable material ensures lasting performance while maintaining an attractive appearance over time.

The 5” and 6” sizes include a 1.5” flange for a strong mechanical connection, further improving stability in demanding applications.
