ECZIEHL-ABEGG

🌀 Next-gen EC ZIEHL-ABEGG motor

At the heart of the Prima Klima ECblue is an electronically commutated (EC) motor from ZIEHL-ABEGG, a global benchmark in ventilation. Compared with a conventional AC motor, it draws up to 50% less power at the same airflow, runs cooler and lasts longer — the expert choice when your indoor grow runs for months at a time. EC technology also means the motor barely loses efficiency as it ages, so the airflow you measure on day one is close to what you'll still get seasons later.

⚡ 680 m³/h of controlled airflow

Pushing 680 m³/h through a 125 mm outlet, this extractor fan refreshes the air of a medium-to-large grow tent several times per minute. Constantly renewed air means stable temperature and humidity, far less risk of mould and pests, and plants that breathe and transpire properly through both growth and flowering. Good extraction also pulls fresh CO2-rich air into the canopy and evacuates excess heat from your lighting, which directly protects yield and plant health.

🎚️ Fully adjustable speed with thermo-controller

The included thermo-controller automatically drives the fan speed based on your room temperature. Set a target and the EC motor speeds up when it gets warm and slows down at night: quieter running, lower energy use and better acoustic comfort. You also keep manual control from 0 to 100%, which is handy when you want a fixed minimum airflow during lights-off or a gentle ramp-up while seedlings establish.

🔇 Quiet operation

Thanks to the impeller's aerodynamics and the smooth torque of the EC motor, the Prima Klima ECblue stays discreet even at high speed. Pair it with a Ø125 mm silencer and it becomes almost inaudible — ideal for a home setup where discretion matters as much as performance. The soft-start behaviour of the EC motor avoids the abrupt switch-on surge typical of AC fans, so there's no sudden noise spike each cycle.

🧩 Complete 125 mm ecosystem

The standard 125 mm connection fits Ø125 mm ducting, odour-neutralising carbon filters, silencers and clamps without any adapter. You can build a coherent extraction kit in minutes and expand your setup later without replacing everything. Standardising on 125 mm keeps spare parts cheap and interchangeable, and makes future upgrades — a larger filter, an inline silencer, a smart controller — completely plug-and-play.

🏆 Prima Klima reliability, curated by BloomLED

Prima Klima is a leading name in horticultural ventilation, known for durability and long service life. At BloomLED, indoor-growing experts for over 10 years, we selected this ECblue model because it offers the best airflow / quietness / consumption balance in its class. Every unit we ship is backed by genuine grower advice, so you can size your extraction correctly the first time rather than learning by trial and error.

What tent size does this 680 m³/h fan suit?

With 680 m³/h it is ideally sized for grow tents from roughly 120×120 cm up to 150×150 cm, or a small grow room. The rule of thumb is to renew the room's air volume at least every 1–3 minutes; leave some headroom if you add a carbon filter, which slightly reduces real-world airflow.

Is the thermo-controller really included?

Yes. The ECblue model ships with its thermo-controller, which automatically regulates the EC motor's speed according to the measured temperature. You don't need to buy a separate speed controller to get started; you can of course pair it with a Prima Klima EC regulator or a Growcontrol controller for more advanced setups.

Do I need a carbon filter with this fan?

If you want to neutralise odours, yes: fit a Ø125 mm activated carbon filter on the intake side. The Prima Klima ECblue keeps enough airflow reserve to maintain strong extraction even with a filter in place. Choose a filter whose rated airflow is close to that of the fan.

How is it different from a classic AC fan?

An EC (electronic) motor like the ECblue's offers far higher efficiency: lower power draw, continuously adjustable speed without torque loss, soft start, less heat and noise, and a longer lifespan. It's the preferred option for demanding growers.

How do I keep noise to a minimum?

Three levers: mount the fan on soft suspensions or anti-vibration straps, add a Ø125 mm silencer to the duct, and let the thermo-controller lower the speed when temperature allows. The EC ZIEHL-ABEGG motor does the rest, staying smooth and discreet even under sustained load.

The performance of an EC ZIEHL-ABEGG motor, the quietness of a premium extractor and automatic speed control included: the Prima Klima ECblue 125 mm is the go-to fan for managing your indoor grow's climate without compromise.
