Description
Description
APPLICATION  
  • 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.).
DESIGN  
  • 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.
  • The diffuser, the specially profiled impeller and the directing vanes at the outlet of the fan casing distribute air flow in such a way as to attain the best combination of high performance and high pressure at low noise level.
  • The fan casing is equipped with an outer airtight terminal box for connection to power mains.
ELECTRIC MOTOR  
  • The units are equipped with highly efficient electronically commutated EC motors. These state-of-the-art motors are the most advanced solution in energy efficiency today. 
  • EC motors are characterised with high performance and optimum control across the entire speed range.
  • In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
SPEED CONTROL  
  • The fan is controlled with the 0-10 V control signal (capacity control is performed depending on the temperature, humidity, pressure and other parameters).
  • When the value of the control factor changes, the EC fan changes the rotation speed and supplies exactly the amount of air required by the ventilation system.
  • Maximum fan speed does not depend on the available current frequency and is suitable for operation both at 50 and 60 Hz. 
  • Several fans can be integrated into a single computer-driven control system.
  • Custom designed software provides high accuracy control of the fans integrated into a network.
  • The computer display shows all the system parameters and the operation mode can be set individually for each fan in the network.
MOUNTING  
  • The fans are intended for mounting to round air ducts.
  • The fan casing has mounting brackets for floor, wall or ceiling mounting.
  • Any installation angle relative to the fan axis is permissible.
  • Access for the fan maintenance shall be provided during mounting. 
  • For wiring installation and mounting of the fan follow the guidelines in the user's manual and wiring diagram on the terminal box.
  • Several fans may be installed in one system in parallel to attain higher air capacity or in series to increase operating pressure in the system.
