At BloomLED, an indoor-growing specialist for over 10 years, we know that climate control makes or breaks your harvests. The Prima Klima WhisperBlower EC-TC Ø150/160 mm extractor delivers everything a demanding grower expects from a premium extraction system: an impressive maximum airflow of up to 1400 m³/h, remarkably quiet operation thanks to its WhisperBlower sound insulation, and a next-generation EC ECblue motor driven by a built-in thermo controller. The result is powerful, fully adjustable air renewal that clears heat, humidity and odours without turning your grow space into a wind tunnel. It is the go-to tool for growers who refuse to choose between performance and discretion, and who want dependable gear built to last season after season. Whether you run a single large tent or a full grow room, this extractor gives you the headroom to add a carbon filter and long ducting runs without ever running out of breath.

The WhisperBlower sound insulation wraps the motor and strongly dampens vibration and air noise. You get powerful extraction without the racket, ideal for a discreet grow in a living space or apartment. Your neighbours will not hear it, and neither will you.
Designed for large spaces and demanding setups, it quickly renews the air in your tent or grow room. Excess heat, humidity and stale air are continuously evacuated to keep your plants vigorous and healthy. Stable temperature and humidity mean tighter internodes, stronger transpiration and a noticeably better end result.
The built-in thermo controller and its remote probe automatically adjust fan speed to the temperature measured in your space. You set your minimum and maximum thresholds, and the EC motor adapts airflow in real time for a consistently stable climate. No more night-time heat spikes or abrupt swings that stress your plants.
The patented Prima Klima flange accepts both 150 and 160 mm ducting. This versatility lets you optimise your air circuit and reuse your existing ducting without an extra reducer or improvisation.
The brushless ECblue motor is far more energy-efficient than a conventional AC motor. At just 170 W you enjoy generous extraction while keeping your electricity bill under control across long grow cycles. It is an investment that pays for itself every cycle through measurable energy savings.
Its power reserve is designed to offset the pressure drop of an activated carbon filter. You keep excellent effective airflow while neutralising odours efficiently, for a fully controlled grow from start to finish.
With a maximum airflow of up to 1400 m³/h, it suits large tents and grow rooms. As a rule you aim to renew the volume of the space several times per minute: this model offers a comfortable power reserve, even after fitting a carbon filter and several metres of ducting. When in doubt, sizing up slightly and running the fan at a lower speed is always the quieter, more efficient choice.
Is it really silent?Yes. WhisperBlower technology combines an acoustic insulation shell with an EC motor that is inherently smoother than AC motors. By modulating speed via the thermo controller, you can lower the noise level even further when maximum power is not needed.
How does the built-in thermo controller work?A remote temperature probe sits in your grow space. You set a minimum speed, a maximum speed and a target temperature: the EC motor automatically speeds up when it gets too hot and slows down as the temperature falls, for a stable climate with no manual intervention.
Can I pair it with a carbon filter?Absolutely, and it is recommended. The extractor is optimised to offset the pressure drop of a compatible activated carbon filter. Remember to size the filter to the airflow so odours are neutralised without throttling ventilation.
What is the difference between 150 and 160 mm ducting?The Prima Klima dual flange accepts both diameters. The 160 mm offers a slightly larger cross-section and therefore a little less air resistance; the 150 mm remains the most common standard. Choose according to your existing equipment, with no reducer or DIY needed.
The winning combo for expert growers: the power of a 1400 m³/h extractor, the silence of a WhisperBlower and the intelligence of a thermo-regulated EC motor, all hand-picked and supported by the BloomLED team.
