Vents TT 125 T is a fan with a delay timerto turn off the fan in the range from 2 to 30 minutes after turning off the power supply.
VENTS TT fans combine wide capabilities and high performance of axial and centrifugal fans. They are used in supply and exhaust ventilation systems that require high pressure, powerful air flow and low noise levels. Compatible with air ducts with a diameter of 100, 125, 150,160, 200, 250, 315 mm.
TT fans are an excellent choice for installation in exhaust systems of rooms with high humidity (bathrooms, kitchens), as well as for ventilation of apartments, cottages, shops, cafes, cinemas, etc. A wide range of models and a large selection of options allows you to choose a fan that meets your requirements.

Design
The Vents TT 125 T fan housing is made of high-quality and high-strength materials: ABS -plastic (100-200) and low-flammability polypropylene (250-315). The motor block with impeller and terminal box is attached to the fan housing using special snap-on clamps designed in such a way that its dismantling can be easily done without special skills and tools. This design greatly simplifies fan maintenance.
All models can be equipped with an adjustable timer with a fan shutdown delay range from 2 to 30 minutes (TT&hellip,T). For more convenient connection and use, the fan can be equipped with a power cord with a plug (TT&hellip,P).
Motor
The single-phase motor on rolling bearings has two speeds. For some standard sizes, an engine version with more powerful characteristics is available (TT&hellip,C). To protect against overload, the fan motors are equipped with thermal fuses. Motor protection class – IPX4.
Speed adjustment
The two-speed motor is controlled using an external speed switch. If it is necessary to regulate the speed smoothly or stepwise, you can use a triac or autotransformer regulator by connecting it to the maximum speed terminal of the motor.
Installation
Fans can be installed at the beginning, middle and end of the air duct system. Installation at any angle relative to the fan axis is allowed. In one system, it is possible to install several fans in parallel (to increase productivity) or in series (to increase operating pressure).
The fan housing is equipped with a flat mounting plate, with which the fan is attached to the wall. Electrical connection and installation must be carried out according to the instructions and wiring diagram indicated on the terminal block. For ease of installation and connection, the mounting box can be installed in any position.
