SwedVent Ventilation Systems

GIA SwedVent undertakes the design and calculations for total ventilation systems, supplying heavy-duty high pressure axial flow fans for airflows from 2.5 to 200 cu m/sec and in diameters of 630 to 2,240 mm. These are characterised by high efficiency, low energy consumption and low noise generation, and are delivered with all necessary accessories such as silencers, starters and variable airflow devices. SwedVent flexible ducting is manufactured from PVC-coated polyester fabric in diameters from 300-3,000 mm and lengths of 10-100 m, together with any bends and branch pipes required.
