Ravenscroft BSD (Series 2) circular fire damper is now available for plasterboard walls. The updated version of our BSD damper meets the AS1530.4-2014 standard and passed its recent test with flying colours.

The Ravenscroft BSD (Series 2) has the same benefits as the older version. It allows for fast installation and is specifically designed for installation in plasterboard walls. There is no need for a separate balancing damper or duct access hatch. The damper is supplied as a kitset for easy installation.

Available in sizes: 125 mm dia, 150 mm dia, 175 mm dia, 200 mm dia, 250 mm dia,  300 mm dia and 400 mm dia.
