Prima Klima PK250EC-TC 1450m³/h Ø250mm – Temperature-Controlled EC Fan for Professional Ventilation
The Prima Klima PK250EC-TC is a powerful, temperature-controlled EC fan with a 250 mm connection diameter and an air flow rate of up to 1450 m³/h. It is the ideal solution for efficient room ventilation, indoor climate control, and operation with activated carbon filters. Thanks to modern EC technology, this fan combines maximum performance with top energy efficiency, while remaining whisper-quiet during night operation.
Advantages of the Prima Klima PK250EC-TC
-
Enormous power – up to 1450 m³/h air flow rate at 250 mm diameter
-
Energy efficiency A++ – up to 30% power savings compared to AC fans
-
Stepless speed control for quiet, vibration-free operation
-
Automatic temperature control – maintains a stable room climate
-
Optimized for activated carbon filters – high pressure build-up for reliable odor neutralization

Flexible Control for Every Room Climate
With the Prima Klima PK250EC-TC, three parameters can be set: minimum speed, desired temperature, and maximum speed. This ensures that a constant negative pressure is maintained even at night, while the fan automatically increases its speed during the day to maintain the desired temperature. If smaller activated carbon filters are used, the maximum speed can be specifically limited.

EC Motor – Technology that Impresses
An EC motor (Electronically Commutated Motor) operates brushless and uses permanent magnets in the rotor. This results in less friction, leading to a longer lifespan, less maintenance, and higher energy efficiency. The integrated control electronics allow precise speed regulation – either directly on the device or via external climate controllers. The result: quiet, efficient, and reliable ventilation.
Tips & Tricks for Optimal Use
- Place the temperature sensor in the center of the room, away from direct heat sources or drafts.
- Set the minimum speed so that a slight negative pressure is maintained even at night.
- For long duct runs, use insulated ventilation hoses to minimize noise and performance loss.
- Regularly clean the pre-filter of the activated carbon filter to ensure constant performance.
- For particularly quiet operation, silencers or acoustic boxes can be additionally installed.

FAQ – Frequently Asked Questions
Is the fan suitable for continuous operation?
Yes, the PK250EC-TC is designed for 24/7 operation and is extremely reliable.
How loud is the EC fan?
Virtually silent in night mode; generally quieter and with less vibration compared to AC fans.
Do I need an additional climate controller?
No, temperature control is already integrated. However, external controllers are compatible.
Can I operate the fan with smaller activated carbon filters?
Yes, the maximum speed can be limited to prevent overloading the filter.
What is the difference between EC and AC fans?
EC fans are more efficient, quieter, more durable, and save electricity costs in the long run.
