VENTS TT 250 duct fan

Inline mixed-type fan VENTS TT 250 is a fan model with a modern design, which actually combines the features of the operation of axial and centrifugal fans. The device is characterized by compact in-duct installation (designed to be placed in channels with a diameter of 250 mm), with fixing with a mounting plate.

Functions and application features of the VENTS TT 250 fan

Industrial fans of the presented model carry out an extract and a flow of air masses. To optimize performance, you can additionally equip them with:

timer;

Regulator;

Mode switch.

The relevance of the fan application is especially important for the following cases:

When the application of high pressure and power of air flow in the system is required;

If it is necessary to ensure the supply and exhaust of a large amount of air (for example, in a large room);

When the absence of high noise levels is important.

Benefits of design and application

The design is simple and does not require detailed disassembly, which simplifies maintenance;

The case is durable;

The single-phase motor has protection against overheating, and therefore its overloads are excluded;

When installing the engine, rolling bearings are used, prolonging the life of the engine without failures;

Mounting ensures compactness of the fan;

You can install the fan at any point, with any slope, while maintaining its quality characteristics.

Brief description of the design

VENTS TT 250 mixed-type duct fans use ABS plastic, lightweight, durable and resistant, as a material. To install the main structural elements, the fan has a special central block. The motor can be single or double speed. An impeller is attached to the engine, and terminals for connecting power are also located in the central (removable) part of the structure. Branch pipes are attached to the central block with the engine and the impeller. To fasten them, clamps with latches are used, reliable, but which are easy to detach if necessary.

Installation of duct fans VENTS TT 250

VENTS TT 250 round duct fans can be installed in the system:

At the same time, the amount of air consumed will be increased;

Consistently, the pressure created in the system will be increased.

To control the speed of rotation of the impeller, the VENTS TT 250 inline mixed-type fan can be controlled using:

Switch (built-in, option B or external model P2-1-300 or P2-5.0);

Regulator (built-in, option P or external).

External devices can be purchased separately. You can use the regulator of an autotransformer or triac circuit.

Temperature maintenance module

The element will be relevant for ventilation systems of premises with the need to maintain the air temperature during ventilation. The electronic temperature and speed module adjusts the speed of the impeller so that the temperature in the room is constant, set (its current value is measured by the sensor).
