Application of the duct fan Vents TT 150
The VENTS TT 150 models are a great example of a device that combines extensive technical capabilities and very high parameters of axial and centrifugal fans. This mechanism is used in supply and exhaust ventilation systems that require high pressure, strong air flow and a minimum noise field. These models are suitable for air duct systems with a diameter of 150 mm. The specified fan models are perfect for installation in exhaust systems of rooms where the humidity level is significantly higher than normal (bathrooms, kitchens). Also, these devices will perfectly cope with the ventilation of space in residential apartments, country cottages, restaurants or grocery stores.
Design of the VENTS TT150 fan
The fans of the specified models are assembled only from the best parts. The device body was made of high-quality and super-strong material: ABS plastic. The central block with motors is a removable part. It is attached to the pipes by the impeller and terminal box using special clamps on latches. Such a system greatly simplifies the maintenance of the device and makes this procedure as simple as possible.
In order to clean the fan or check its technical capabilities, you no longer need to disassemble the electrical appliance completely. It is enough to remove the central unit and carry out all the necessary procedures. Adjustable timers can be installed on absolutely all models of VENTS TT 150 series fans. The range of the device shutdown delay for these timers is from 2 to 30 minutes. VENTS TT150 fans are equipped with single-phase two-speed motors of the highest quality, which significantly reduce energy consumption, thereby allowing significant savings on this. To avoid overload, thermal fuses are installed on each device. Thanks to rolling bearings, the service life of these fans is about 40,000 working hours. IP X4 is the protection class of the device motor.
Speed control for fans VENTS TT 150
There are several ways to control the two-speed motor. The first way is to control it using a built-in toggle switch (option B). The second way is to control it using an external switch P2-1-300 or P2-5.0, which is used on multi-speed fans and is purchased separately. You can also adjust the speed of rotation using a built-in regulator (option P) of an external thyristor or autotransformer switch, which is purchased separately. To start working, you need to connect the parts to the terminal that controls the maximum speed of the fan motor.
Installation of duct fan VENTS TT 150
The VENTS TT 150 models can be installed in any place of the air duct system at the beginning, middle and end. Also, fans of this series can be mounted at any angle of the fan axis. It is also worth noting that several devices can be installed in one air duct system:
Fans are installed in parallel (increases air flow);
The fans are mounted in series (this increases the working pressure).
The device can be mounted to the wall thanks to the fan housing, which is equipped with a flat mounting plate. In order to make it easier for owners of these fans to mount the device, the mounting box can be installed in any position.
Operating principle of a fan with an electronic temperature and speed module
To set the desired temperature (thermostat threshold), simply turn the control knob to the desired level. To adjust the minimum blade rotation speed (air flow), you should adjust the impeller rotation speed using the rotation knob. If the room air temperature rises and can exceed the permissible level set in the thermostat at any time, the fan automation turns on the device's motor to maximum and begins to increase the blade rotation speed. After the temperature begins to return to normal, the automatic system will begin to reduce the speed and eventually return to the parameters set at the beginning. In order to eliminate frequent speed changes by the fan motor, the designers introduced delays in switching modes.
A delay can only occur in a few cases:
Delay configured for the temperature sensor (option "U"). If the temperature sensor detects an increase in thermal indicators by 2 degrees or more, the automatic system is activated, which increases the rotation speed to the maximum. Return to the initial speed parameters will occur only after the room temperature has dropped to the level set in the thermostat. This function is usually used for precise adjustment of the air temperature in the room. Usually, during this operating mode, fan switching occurs extremely rarely.
Delay set to timer (option "U1"). If the temperature sensor detects an increase in thermal indicators in the room, a mechanism is triggered that increases the speed to the maximum and activates the delay timer for 5 minutes. Return to the initial speed parameters will occur only if the temperature returns to the initially set parameters and only after the delay timer has worked for the required time. This function is used for more precise adjustment of thermal indicators in the room. At the same time, using this function, the fan will switch much more often than with a temperature sensor delay, but the interval of these delays will be at least 5 minutes.
