The DD Series Duct Balancing Damper was designed for duct installations to balance/regulate airflows.
All spindles revolve in low maintenance nylon bushes which are fitted within pressed inserts. Precise blade positioning is achieved via a robust dual-purpose quadrant and spindle assembly, operating the linkage mechanism which is located outside of the airstream.

One of the outcomes of the Grenfell Tower enquiry Phase 1 report was that there was a lack of on-site information available to the Fire Brigade on the night of the fire. Consequently, The Fire Safety (England) Regulations 2022 have made it a legal requirement for residential buildings abovre 7 storeys or 18 metres to have secure information boxes containing key fire safety plans located on the premises.
Nearly three years since the Hackitt Report’s publishing, the construction industry has been subjected to gradual changes by introducing regulations. However, the industry will likely face more changes to the legislature.
