CCD-01 Control Damper
The CCD‑01 Control Damper provides reliable airflow control and positive shut-off in demanding industrial ventilation systems, combining robust construction with flexible operation for balancing, isolation and air recirculation applications.
Overview
The CCD‑01 Control Damper is designed to provide reliable airflow control and positive shut‑off performance under arduous operating conditions. Intended for use in hazardous and industrial environments, its robust construction ensures dependable operation and long service life. Suitable for both manual and automatic operation, it supports a wide range of functions including system balancing, fan shut‑off and fresh air recirculation. The damper may be installed in any orientation, with airflow in either direction, offering flexibility for a wide range of ductwork configurations.
Key Features
Casing
The damper casing is formed from 3.0 mm thick sheet steel into a rigid channel section to ensure proper alignment of blades and shafts. The CCD-01 is available as a single unit, maximum size 1275mm x 1800mm, or as a multiple unit assembly, maximum size 3925mm x 3650mm. The insertion length is 300mm. Where circular dampers or dampers with width or height dimensions less than 150 mm are required, additional spigot adaptors are used.
Blades
The blades are a formed double-skin aerofoil section of 1.5 mm sheet metal and operate with an opposed linkage. Blade stops at the top and bottom of the casing and sprung side seals provide excellent low leakage characteristics.
