Made of PVC, these louvers stand up to acids, alkalies, salts, and corrosive vapors in harsh environments and won’t rust.

Constructed with a thick frame and blades, these louvers have a long service life.

Designed with blades that drain water down the jambs, these louvers keep water from running down the front of the blades, even in harsh weather.

The included filter cleans the air as it passes through these louvers.
