VENTS TT 250 duct fan
Mixed type duct fan VENTS TT 250 is a fan model with a modern design, which actually combines the features of axial and centrifugal fans. The device is characterized by compact in-duct installation (designed for placement in ducts with a diameter of 250 mm), with fastening by a mounting plate.
Functions and features of the VENTS TT 250 fan
Industrial fans of the presented model perform exhaust and flow of air masses. To optimize their operation, they can be additionally equipped with:
Timer;
Regulator;
Mode switch.
The relevance of using a fan is especially important in the following cases:
When high pressure and air flow power is required in the system;
If it is necessary to provide the inflow and exhaust of a large amount of air (for example, in a large room);
When it is important not to have a high noise level.
Advantages of design and application
The design is simple and does not require detailed disassembly, which simplifies maintenance;
The body is durable;
The single-phase motor has overheating protection, and therefore its overloads are excluded;
When installing the engine, rolling bearings are used, which extend the engine’s service life without failures;
The installation ensures the compactness of the fan;
The fan can be installed at any point, at any angle, while maintaining its quality characteristics.
Brief description of the design
Mixed type duct fans VENTS TT 250 use ABS plastic as a material, which is lightweight, durable and resistant. The fan has a special central block for installing the main structural elements. The engine can be single- or double-speed. An impeller is attached to the engine, and terminals for connecting the power supply are also located in the central (removable) part of the structure. Branch pipes are attached to the central block with the engine and impeller. Clamps with latches are used to secure them, they are reliable, but can be easily disconnected if necessary.
Installation of duct fans VENTS TT 250
Fans for round ducts of the VENTS TT 250 type can be installed in the system:
At the same time, the amount of air consumed will increase;
The pressure created in the system will be gradually increased.
To regulate the impeller rotation speed, the VENTS TT 250 mixed-type duct 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 an autotransformer or thyristor circuit regulator.
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 impeller speed so that the room temperature is constant, specified (its current value is measured by the sensor).
