Product Description

Shaft Louvre Damper – Residential (SLD-R), are multizone smoke control dampers and designed for use in mechanical smoke ventilation systems. They are typically installed into shafts to provide extract ventilation to corridors and into smoke control ducts in residential and commercial buildings.

They are certified to BS EN 12101-8:2011 and have a fire resistance class of EIS 120. They may be used in multi-compartmented smoke control ducts and have an integrity and insulation of 120 minutes. In addition they have been tested for reliability up to 10,000 cycles and may be used for environmental ventilation.

They are manufactured with a galvanised casing, and fire rated multi-blade louvres and operate by a drive open/drive close 24V AC/DC Belimo actuator. They are supplied with a removable white linear grill internally which provides a neat finish whilst enabling quick access for commissioning and service.
