Howorth Air Technology, has developed a new Screenless Exflow Ultra Clean Canopy to complement the range of Exflows it has been installing in private and public hospitals around the world for over 40 years. When designing the Screenless Exflow, Howorth could have easily taken the approach adopted by its competitors: positioning bulky low level recirculation ducts around the theatre with fans and chilled water coils in the theatre ceiling void or in vertical ducts around the theatre, necessitating plant and ductwork systems which are totally impractical in most retrofit situations. However, in keeping with the company’s innovative approach to design, Howorth chose to rather develop its own unique system which is suitable for both retrofits and new builds. Howorth’s Screenless Exflow essentially retains the basic construction of its market leading existing models, the Exflow 28 and Exflow 32, but with some innovative engineering at the air discharge, the company has recreated, and in many ways improved, the performance of the systems without the need for the partial walls or the additional requirement of low level recirculation ducts, remote fans or cooling coils. The unit remains an integral fan unit of modular construction, ideal for new build or retro-fit situations. Installation time is kept to an absolute minimum and long term maintenance costs are lower than competitive products.
