Why are TT PRO fans professional?

The TT PRO 250U plastic duct fan with a thermostat is designed for ventilation systems that operate under high pressure and require minimal noise. The main advantage of this fan is its fire-resistant polypropylene housing, higher performance, and additional features such as delayed start, interval operation, and run-on. TT fans are intended for ventilating spaces that require continuous air exchange (workshops, stores, offices, residential areas, bathrooms, greenhouses, or growing areas, etc.). The fan’s plastic body includes a mounting plate for wall or ceiling installation. It is corrosion-resistant and can be used in humid environments.

The electronic temperature sensor ensures automatic speed regulation based on the ambient or duct temperature. When the temperature rises by 2 degrees above the set value, the fan switches to a higher speed. It returns to the original speed when the temperature decreases. Detailed instructions are provided in the Czech manual.
