Iris Dampers

Iris dampers use interlocking steel plates and a calibrated control lever to form an adjustable aperture.

By measuring differential pressure across the pressure ports, and referring to the matching performance curve, airflow can be precisely determined.

Ten sizes are available, from 4 to 32 in., with capacities to 20,000 cfm. Iris dampers are made from galvanized steel. The dampers are fitted with a neoprene gasket for airtight mounting and come in stainless-steel and motorized versions.
