The single ‘door sized’ S61 compliments the company’s established, successful UKCA certified and CE marked Series 60 (S60) smoke evacuation damper.

The new S61 has been designed, tested and certified to EN1366-2, EN1366-10 and EN12101-8 in both open-to-closed and closed-to-open (with its associated grille attachment). It has attained ES classification for integrity and smoke in air leakage tests, exceeding current legislative requirements and guidance. As its counterpart Series 60, S61 is manufactured from galvanised steel and will provide up to 120 minutes’ smoke and fire integrity.

Providing up to 1m2 geometric free area within a 800mm x 1920mm opening list size, S61 delivers a unit specifically to suit mechanically ventilated smoke shafts, with its enhanced air leakage reduction. Front access actuators and grille alignment brackets further simplify installation, operation and maintenance.

Says Ian Rogers, Gilberts’ Sales Director: “Series 60 goes from strength to strength: we believed it was the best of its kind when launched, and that has been reinforced with its attainment of certification for maintenance of opening confirmation. It remains the ‘go to’ option. Series 61 is engineered to offer specifiers an alternative with improved area and smoke leakage when exceptional capability is demanded, with an increase in size to suit mechanically ventilated shafts and enhanced leakage reduction.”

The development of S61 builds on Gilberts’ 60+ years’ heritage of bringing to market advanced technology that enhances the design, installation, energy efficiency and occupier comfort of non- domestic buildings.

All Gilberts’ products- standard lines and bespoke solutions- are designed, developed, manufactured and tested in accordance with BS EN ISO 9001:2015 quality standard in the company’s state of the art 95,000 ft2 facility in Blackpool.
