SHUT-OFF DAMPERS

Airflow setting and control

Damper 11055116

RGE Ø355 Manual and Motorised with kit

The RGE damper uses a motor or manual operation to balance and isolate a circular ducting system, while ensuring a very low leak rate.

PRODUCT BENEFITS

Class C airtight performance as per EN 1751
Manual or motorised operation using plate kit

Principles of Operation

The flap of the RGE manual damper is opened and closed by rotating a handle or using a motor after a motor plate is installed. If it is closed, the airtight seal is formed by the moulded seal on the disc.

Product Description

The RGE damper balances airflow and isolates a circular ducting system. It features a sealed disc to minimise air leaks between upstream and of the damper in the closed position and double-lip airtight seals on each junction to minimise leaks with the rest of the system. Its top jumper enables overlaid insulation without covering the lockable handle.

Fields of Application

Non-residential buildings

Installation

Installed in circular ducts.

Diagram illustrating the installation of a motorisation plate onto the RGE damper. It shows a circular duct connection, the damper body, and a mounting plate with a central shaft connection, labeled 'For CM model only' and indicating a Ø12 connection.

Reference Arguments

Damper air tightness provided by jointed disk (overmoulding on disk providing good long-term resistance).
Double-lip airtight seal on each junction.
RGE: screw-locked adjustment handle. Zamak shafts.
Upper jumper provides overlaid insulation without covering handle.
To motorise RGE dampers beyond 355 mm: order the universal adapter plate (11055122) separately to enable installation of any motor.
Motor power: 2 N/m for RGE Ø 125 to 200, 4-5 N/m for RGE Ø 250 to 500.
Beyond Ø 500 mm, for reasons of mechanical resistance, use a CRGE volume control damper with connecting plates of the same Ø as the ducting.

Main Characteristics

Galvanised steel construction.
Airtight performance upstream/downstream of disc: class 4 as per EN 1751.
Class C product airtight performance as per EN 12237.
Motor plate ordered separately.
Motor ordered separately: 4-5 N.m for RGE Ø 355 to 450 and 10 N.m for RGE Ø 500 mm.
Temperature range: 0 to 120°C.
