Vents Stream 150/160 EC Un Mixed-Flow In-line Fan Ø 150/160 MM 600 M³ (Temperature Control and Sound Insulated)

The Vents Stream 150/160 EC Un Mixed-Flow In-line Duct Fan is incredibly quiet thanks to its sound and heat-insulating housing. It is equipped with a temperature-controlled controller and has a maximum capacity of 600 M³ per hour with a Ø 150/160 mm connection. The 150/160 EC Un is compatible with air ducts of Ø150 and 160 mm.

The Vents Stream 150/160 has Ø 150 mm connections on both sides and is supplied with two adapter seal rings Ø 150 to Ø 160 mm.

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, education- al institutions, kindergartens etc.).

Casing
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 combi nation 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.

EC-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 characterized with high performance and optimum control across the entire speed range. In addition to that, the efficiency of the electronically commutated motor reaches very im- pressive levels of up to 90 %.

Speed control with thermostat
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.

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.

Optional
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.
