This excellent device has multiple benefits that make it the most cost-efficient damper to install and use.

On installation, there is no need for flanges, gaskets or bolts. Just ensure that the orientation of the unit is suitable, and fix the damper to the ductwork, either with rivets or a screw.

You can accurately balance your system using the measurement nozzles, thus removing the fuss of drilling and plugging holes. The airflow can be determined by comparing the measured value on the differential pressure chart.

PRA uses a conical iris, which is the most aerodynamic solution. The fully opened product also allows for easy cleaning.

During its operating life, the PRA generates minimal sound, making it once more, the perfect solution. We at Halton aim to solve all your airflow problems, and we aim to create a perfectly balanced atmosphere for our clients.
