CIRCULAR LENTICULAR DAMPER Characteristics: A circular lenticular damper used for airflow control with connector pipes for pressure loss measurement. Adjusted manually. IRIS lenticular dampers are intended for installation in circular air supply or exhaust ventilation systems. They are used for the airflow rate control by means of a smooth change in the orifice internal diameter. Lenticular dampers are made of galvanised steel. A lever with locking screws is used for adjusting the internal diameter. Damper connections are dimensionally suited to the internal dimensions of ducts and rubber gaskets ensure the tightness. It is recommended that the duct segments are kept straight: Table 1. Standard dimensions of IRIS dampers. Circular lenticular damper
