Product Description

High quality single blade Round Volume Control Dampers are designed for quiet, efficient and reliable air volume control in ventilation systems. The damper is used for regulating air flow or as shut􀀂off damper when complete sealing against air flow is not required.

COSMOS Round Damper allows even distribution and control of airflow under conditions of high duct pressures.

COSMOS provides top quality round dampers to control air flow in Heating, Ventilating, and Air Conditioning (HVAC) systems that fit standard round ducts.

Casing and blades made from galvanized steel sheet. The round casing is manufactured by rolling suitable size GI steel sheet and swaging at both ends to accommodate ductwork connections. Adjustable damper blade mounted on nylon bushes with manually operated quadrant and position indicator.

The blades are single skin cut to round shape, reinforced at center to accommodate spindle assembly and provide toughness. Dampers can be manual with locking quadrant and position indicator or motorized with a wide range of electrical actuators.

A variety of options are available to meet specific installation requirements and a comprehensive selection of electric or pneumatic actuators are available for factory or field mounting.

Model RVCD is manual air flow control damper and RVCD􀀂M is electrical flow control damper.
