Vents TT 315 is a duct-type fan for exhaust or supply ventilation.
Vents TT fans combine the 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 315 mm.
Vents TT 315 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.

Aerodynamic diagram characteristics
Design
Vents TT 315 fan housings are 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...T). For more convenient connection and use, the fan can be equipped with a power cord with a plug (TT...P).
Motor
The single-phase motor on rolling bearings has two speeds. For some standard sizes, a motor version with more powerful characteristics is available (TT...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 (purchased separately). If it is necessary to continuously regulate the speed, you can use a thyristor regulator RS-1-400 by connecting it to the maximum speed terminal of the motor.
If stepwise speed control is required, then it will do regulator P2-1-300. With its help, you can also, in addition to adjusting the fan performance, simultaneously turn on or off the lighting.
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.
