Product detailed description

The smaller TT 125S U plastic fan has a maximum airflow of 320 m³/h and is designed for ventilation ducts with a diameter of 125 millimeters. The main advantage of this fan is its electronic temperature sensor, which ensures automatic speed regulation based on the surrounding 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.

Why is a duct fan with a thermostat advantageous?

Fans from the TT U series are equipped with a thermostat, allowing for automatic speed regulation according to the ambient temperature. They are ideal for systems that operate under high pressure and require minimal noise. Their versatility makes them suitable for small spaces that require frequent or continuous air exchange (offices, kitchens, bathrooms, greenhouses, workshops, or growing areas).

The fan's plastic body features a mounting plate for wall installation. An adjustable timer is available as an additional accessory. Detailed installation and usage instructions are provided in the Czech manual.
