Perforated Metal Ducting for Air Distribution

Perforated metal ducting is a supply-air distribution solution for industrial and commercial spaces. Air is discharged through a perforation pattern engineered along the duct so that direction and distributed volume match the served area.

The system can be integrated into exposed ventilation routes. Duct geometry, material, finish, joints and suspension are specified for each project.

Correct sizing considers airflow rate, available static pressure, route length and geometry, installation height, supply-air temperature and the target air velocity in the occupied zone. Duct diameter alone is not sufficient to select the perforation pattern.

For design and quotation, provide ALWO with airflow, available pressure, the space layout, installation height and operating conditions.
