Centrifugal fan STREAM EC SERIES

axialductcommercial

Sound- and heat-insulated mixed flow duct fans with air flow up to 600 m³/h and with EC motor. The VENTS Stream EC series of duct fans is available in a special sound-insulated casing that ensures silent fan operation with high aerodynamic performance. Compatible with Ø100 to 160 mm air ducts. The VENTS Stream EC fans combine wide capabilities and high technical parameters of axial and centrifugal fans, providing powerful air flow and high pressure as well as cost-effectiveness and manageability of the EC motor. 100% variable speed, multiple fans can be connected to a computer control system equipped with sensors. Application: intended for supply and exhaust ventilation systems of different commercial and industrial premises with high demands on energy efficiency and noise level (libraries, conference halls, educational institutions, kindergartens etc.). The outer casing is made of high quality and durable plastic. The internal perforation of the casing allows sound waves to pass through, directing them at a certain angle onto a layer of sound-insulating material. Heat- and sound-insulation of the casing are made of a 50 mm layer of non-flammable mineral wool. The special perforation of the casing and the sound-absorbing material ensure that sound is attenuated over a wide frequency range. Due to the conic impeller and special blade profiling the circumferential air speed increases thus providing higher air pressure and capacity as compared to standard axial fans.
