Improve indoor air quality with our NEW CD-25R-CO2 Control Damper with Carbon Dioxide Sensor.

Featuring a modulating Belimo actuator and A CO2 room sensor, this product measures the carbon dioxide levels and sends a signal to the damper to open at desired set-points, allowing fresh air intake.

Reduce Labor and Achieve a More Aesthetic Look with our Louver Mullion Seam Cover.

This option not only gives our louvers a more enhanced appearance but the cover helps maintain appropriate louver spacing and reduces labor when caulking and sealing in multiple sections.

6” Diameter for our True Round FD-125R Fire Damper

Streamline installation with the new option to order our FD-125R Round Fire Damper at a 6" diameter. This lets the damper be connected to a small 6" diameter duct without the need for a square to round connection.
