IRIS

Product catalog summary

Characteristics: The IRIS circular lenticular damper is designed for airflow control in ventilation systems, featuring manual adjustment and pressure loss measurement capabilities. It is constructed from galvanized steel and includes a lever with locking screws for diameter adjustment. Rubber gaskets ensure tight connections.

Intended Use: These dampers are suitable for circular air supply or exhaust systems, allowing for smooth airflow rate control by adjusting the orifice diameter. They operate effectively within a temperature range of -20 to +80°C.

Design Recommendations: For optimal performance, it is recommended to maintain straight duct segments: 4 times the diameter before the damper and 1 time the diameter after the damper.

Dimensions: The document provides a detailed table of standard dimensions for various damper sizes, ranging from DN 100 to DN 800, with corresponding measurements for diameter, length, and weight.

Technical Data: The document includes charts for each damper size (IRIS 100 to IRIS 800) detailing their specific characteristics.

Ordering Information: When ordering, specify the damper diameter using the format IRIS - <D>. For example, IRIS-315 for a 315 mm diameter damper.

Catalog excerpts

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
