The BSB BD Series Backdraught Damper


Blades

The nominal 60mm wide standard extruded aluminium blades are fitted onto 6.25mm diameter spindles, complete with blade edge brush seal fitted as standard.

Please scroll down page to view blade dimensions and position details

All blades are fitted for parallel operation only.

Blades are linked with a precise linkage, minimum two blades and a maximum of 6 blades per linkage set, alleviating movement and subsequent rattling of individual blades. Please refer to pressure drop figures for suitability.

Avoid use of dampers in extremely turbulent duct conditions. Although blade linkages will stabilise blades in most conditions, abnormal circumstances may cause dampers to malfunction.

Horizontal Applications
Where dampers are required to be installed in horizontal applications, a galvanised steel blade limiting stop will be fitted running full length to one side only to prevent locking in the open position. When making an enquiry or placing orders, it is important to inform horizontal or vertical damper position.

Shown above is illustration of standard extruded aluminium blade.
