ELEKTROVENT produces and installs a range of vertical flow ventilation units made up of 12 models in 5 different sizes, with an impeller diameter from 630 to 1000 mm. Industries, underground car parks, shopping centres, schools and hospitals, theatres, museums and all those areas in which it is necessary to guarantee the extraction of fire fumes are the main desination of the Roof-HM centrifugal towers, a series designed and built in compliance to the European directive EN 12101-3 certification issued by a Qualified Autonomous Body.
Suitable for conveying clean air and non-dusty fumes up to a maximum temperature of 120°C in continuous service with peaks up to 180°C or in case of emergency at a temperature of 400°C for 120 minutes (F400). these towers are installed outside the fire risk area. Characterized by high efficiency and aeraulic performance clearly above average, the Roof-HM centrifugal towers have a welded impeller with backward blades and a heat-insulated motor with external ventilation and reach a flow rate of 55,000 m3/h and heads of 2000 Pa.
Accessories:
- Inlet gravity shutter (GS-HM)
