A ‘first of its kind” air movement diffuser is set to revolutionise how comfort conditions are maintained inside commercial buildings.

The Series JSL-T ultra-high-capacity linear slot diffuser with thermal transition is the latest development from Gilberts Blackpool.
Reinforcing our 60+ years’ track record of developing pioneering, innovative ventilation solutions,Series JSL-T automatically adjusts airflow within seconds of any temperature variation being detected to maintain the preset ambient. Thus it delivers the ideal ventilation comfort conditions, consistently.
thermally reactive, no electrical connection
Clever design in the configuration of the plenum and diffuser, and utilisation of thermally reactive components, means Series JSL-T functions without any electrical input or auxiliary power.
In cooling/isothermal mode, air supply of up to 250l/s/m is delivered horizontally. When a variation in temperature is sensed, the diffuser automatically switches to project the air vertically. As Series JSL-T has an airthrow of 5m, this ensures rapid, effective mixing of air within the occupied zone, maintaining the ambient temperature without stratification nor draughts.
The diffuser is relevant for both ceiling and side wall applications. It can also be specified with acoustic and/or thermal insulation. The combination of features optimises its incorporation into almost any building services project in a commercial environment.

a “win:win” scenario
“Series JSL-T is a win:win,” observes Gilberts’ Sales Director Ian Rogers. “Its suitability for both ceiling and side wall applications and its ability to work without any electrical input simplifies the specification and installation of the building services.
“Its speed of reaction and maintenance of the internal temperature optimises occupant comfort which in turn improves people’s productivity, health, morale and enjoyment of the internal space.”
The thermal option compliments the core JSL high-capacity slot diffuser range, which- with its shadow-gap seamless appearance- itself was pioneering when introduced into the market.
Series JSL is just part of Gilberts’ extensive range of grilles, diffusers and louvres for natural and mechanical ventilation, all designed to contribute towards simple attainment of ideal ventilation comfort conditions.
Gilberts has a significant portfolio of delivering ventilation solutions for high-end projects, for which Series JSL-T will meet the design and sustainability criteria, including Google’s London offices, Birmingham’s tallest office building the BREEAM Excellent 103 Colmore Row, the Grade II listed India Building Liverpool and Twitter’s LEED platinum EMEA headquarters in Dublin.
Founded some six decades ago, today family-owned Gilberts’ 140,000 ft2 head office and manufacturing facility includes its own research and development and test facilities, enabling it to continue to evolve its product range and develop bespoke solutions for specific client requirements. Gilberts is now acknowledged as the UK’s leading independent air movement specialist, offering mechanical, natural and hybrid ventilation solutions.
Its capability includes initial design through tooling, production, testing and supply, within its 140,000 ft2 of manufacturing facilities, incorporating a state-of-the-art test centre, designed and built in-house, which is one of the most technically advanced in the country.
