Reducing site risk and improving certainty in ventilation


Over the past few years, prefabrication has become a necessity in the construction industry. For building services engineers working under increasing pressure to deliver compliant, coordinated and cost- effective projects, offsite assembly presents a practical way to reduce risk while improving certainty

entilation systems, particularly in applications such as smoke control and car park ventilation, are often assembled on site from multiple components sourced


from different suppliers. This traditional approach can present avoidable challenges such as incompatible parts, delayed deliveries and limited storage space. Prefabricated ventilation solutions address these issues at their source. By assembling fans and associated ancillaries within a controlled manufacturing environment, systems can be tested and verified before they reach site. This can include acoustic equipment, flexible connections, controls, mounting frames and panels. This removes complexity from often congested construction environments, improving site safety and reducing risk by shifting assembly into facilities purpose-built for precision manufacturing and quality control. Quality control is imperative in building services


environments, and prefabricated solutions offer a clear advantage. Offsite assembly provides controlled storage and consistent build procedures, aligning closely with the industry’s increasing emphasis on the “Golden Thread” of building information and traceability. Particularly critical for compliance of smoke applications but equally important for general ventilation. The benefits continue with health and safety considerations also being improved. Large fans and systems can be delivered as complete prefabricated assemblies designed with integrated lifting points and site-specific handling


on-site modifications or fitting errors that could compromise both performance and compliance. For contractors and consultants, it provides greater confidence that the installed system will perform as intended in the event of a fire, while also simplifying inspection and documentation processes. Elta will be exhibiting at the Fire Safety Event at the NEC Birmingham from 28 – 30th April, where visitors can learn more about our prefabricated smoke control solutions and more smoke control capabilities. You can find the Elta team on stand 4/D69.


considerations, reducing manual handling and minimising exposure to risk during installation.


The prefabrication advantage for smoke control


Prefabrication is particularly beneficial for smoke control applications, where system compliance is critical. Smoke fans as part of a greater system must operate reliably under extreme conditions and to meet standards such as EN 12101-3. When smoke fans and their ancillaries are engineered and assembled as a complete prefabricated arrangement, performance and certification can be maintained as tested. This includes tested ancillary items including silencers, mounts, dampers, prefab bases etc. Factory assembly ensures that critical elements are installed correctly and verified before dispatch. This reduces the risk of


The future is prefab


As modern methods of construction continue to shape the built environment, prefabrication offers building services engineers a route to greater coordination, reduced on-site risk and assurance of compliance. Rather than viewing offsite assembly as an alternative, it is increasingly being recognised as preferred practice. Elta’s prefabricated ventilation solutions


are developed and assembled within our UK manufacturing facilities, allowing full control of design, fabrication and testing. With over 150,000 potential configurations across standard and smoke-certified ranges, systems can be tailored to meet specific project requirements while maintaining performance integrity.
