Prima Klima Tube fan EC-TC with rotary control

The company PrimaKlima, in collaboration with the well-known company Ziehl-Abegg, has launched an innovative duct fan on the market. The PK125-EC duct fan stands out primarily due to its very energy-efficient consumption, as it is equipped with a new EC motor technology.

Additionally, the duct fan features integrated speed control that produces no humming noises during the dimming process, which is now a thing of the past. In its dimmed state, the duct fan only consumes the energy corresponding to its speed (speed-dependent). Moreover, this model has an upper limit control that allows the performance (speed) to be set in the upper range.

As soon as the set temperature is exceeded, the fan speed automatically increases. When the room temperature returns to the set range, the fan speed decreases back to the set minimum value.

A built-in knob also allows for limiting the maximum speed.

Please note: The PK125-EC-TC duct fan requires approximately 20 seconds of reaction time when adjusting the speed (potentiometer value).

Advantages in the lower operating range:

• No humming noises
• Linear power consumption relative to speed
• Power consumption decreases during pressure build-up
• High motor lifespan, as the motor does not overheat at 30-40 watts

The PK160-EC duct fan comes pre-wired and is therefore ready for connection (Plug and Play) with a mounting bracket and screws included.
