Tips & Tricks for Optimal Results

• Combine the fan with a suitable activated carbon filter (125 mm) for odor-neutral operation.
• Position the sensor in the upper part of the grow tent, where heat accumulates, to obtain precise temperature and humidity values.
• Use flexible hoses with a smooth inner surface to minimize airflow noise and optimize airflow.
• Clean fans and filters regularly – dust and deposits reduce efficiency and increase noise.
• Use the EC fan as part of a coordinated climate system consisting of intake and exhaust air, circulation fans, and climate controllers.

FAQ – Frequently Asked Questions

What is the advantage of an EC fan?
EC motors are more energy-efficient, quieter, and continuously adjustable. They have less heat generation and a longer lifespan than conventional AC fans.

For which grow tent sizes is the 680 fan suitable?
The fan is ideal for medium-sized tents up to approximately 1.5 × 1.5 m footprint or rooms with a similar air volume.

Can I manually override the climate control?
Yes – in addition to automatic operation, the speed can be manually controlled if you wish to take control yourself.

Is continuous use possible?
The Prima Klima EC fan is designed for continuous operation. We recommend letting it run continuously in the ventilation system to maintain stable temperature and humidity.

How loud is the fan?
The noise level depends on the speed. In the low speed range, the EC motor operates whisper-quietly and is barely audible.
