    【Powerful Inline Fan】Made of heavy-duty plastic housing for superior durability, the housing is dusting proof and waterproof, oblique blades add airflow by 40%, single-phase asynchronous motor that delivers a powerful air movement, it only draws 27 watts, but puts out 205 CFM; very low noise level, only produces 26.8DB, this fan is silent; comes with a variable fan speed controller that you can change speed easily.

    【Temperature Regulation】Proper ventilation helps maintain optimal temperatures within the grow space. Plants have specific temperature requirements for growth and flowering. Ventilation systems can expel hot air generated by lights or equipment and bring in cooler air from outside or from a separate cooling system, helping to regulate temperatures.

    【Humidity Control】Controlling humidity levels is essential for preventing mold, mildew, and other moisture-related issues. Ventilation systems can remove excess moisture from the air, especially during the flowering stage when plants are more susceptible to mold.

    【CO2 Distribution】Plants need carbon dioxide (CO2) for photosynthesis. A ventilation system can ensure a steady supply of fresh CO2, which is particularly important in sealed grow rooms where CO2 levels can become depleted over time.

    【Odor Control】Some plants can produce strong odors during flowering. Ventilation systems equipped with carbon filters can help remove these odors, preventing them from escaping the grow room and causing disturbances.

    【Pest Prevention】Good ventilation can deter pests by maintaining airflow and reducing humidity, which are conditions favorable for many pests and pathogens.

    【Disease Prevention】Adequate ventilation helps prevent the spread of diseases by reducing humidity and maintaining a healthy environment for plants.

    【Increased Yield and Quality】By providing plants with optimal growing conditions, including proper airflow, temperature, and CO2 levels, ventilation systems can contribute to higher yields and better quality produce.

    【Temperaturregulierung】Angemessene Belüftung hilft, optimale Temperaturen im Grow-Raum zu halten. Pflanzen haben spezifische Temperaturanforderungen für Wachstum und Blüte. Belüftungssysteme können die heiße Luft, die von den Lampen oder Geräten erzeugt wird, abführen und kühlere Luft von außen oder von einem separaten Kühlsystem einführen, um die Temperaturen zu regulieren.

    【Feuchtigkeitskontrolle】Die Kontrolle der Luftfeuchtigkeit ist wichtig, um Schimmel und andere feuchtigkeitsbedingte Probleme zu vermeiden. Belüftungssysteme können überschüssige Feuchtigkeit aus der Luft entfernen, besonders während der Blütezeit, wenn die Pflanzen anfälliger für Schimmel sind.

    【CO2-Verteilung】Pflanzen brauchen Kohlendioxid (CO2) für die Photosynthese. Ein Belüftungssystem kann eine ständige Zufuhr von frischem CO2 gewährleisten, was besonders in geschlossenen Räumen wichtig ist, in denen der CO2-Gehalt mit der Zeit abnehmen kann.

    【Geruchskontrolle】Einige Pflanzen können während der Blütezeit starke Gerüche erzeugen. Belüftungssysteme, die mit Kohlefiltern ausgestattet sind, können dazu beitragen, diese Gerüche zu entfernen und zu verhindern, dass sie aus dem Grow-Raum entweichen und Störungen verursachen.

    【Schädlingsbekämpfung】Eine gute Belüftung kann Schädlinge abhalten, indem sie den Luftstrom aufrechterhält und die Luftfeuchtigkeit reduziert, was für viele Schädlinge und Krankheitserreger günstige Bedingungen sind.

    【Krankheitsvorbeugung】Ausreichende Belüftung hilft, die Ausbreitung von Krankheiten zu verhindern, indem sie die Luftfeuchtigkeit reduziert und eine gesunde Umgebung für Pflanzen aufrechterhält.

      Works out as fas as I can say for now. I’m wondering about two bags of coal delivered with the filter, I’m not sure sure what to do with that. Am I supposed to fill the filter before the first use? I tried to contact Spider Farmer twice about that but didn’t get any support yet. No instructions delivered with the filter and nothing to find online. Several Reddit discussions about that, several customers are wondering, but still no answer.

        Hello, carbon filter come with carbon, can use it directly.

      it work very nice like it should. the rotor does pull alot of air but it does make a bit noise if you would run it outside your growspace. overall the body is made of nice materials and even the tube is made of good sturdy material and its black wich prevents light leaks and you notice a leak quick. the bands are also good material and easy to hang your fan and filter in. there were some issues with ordering and thats something the european department should look into but it works

    Q & A

    Hello, can i connect the non programmable inline fan with the gss controller if i don´t have the ac power strips? Robin asked on March 20, 2025

    This version can't connect to the GGS controller. Only the inline fan with RJ12 Port can work with GGS Controller

    I got the filter with two bags of coal. Is the filter pre-filled or do I need to fill it using the coal delivered with it? Stefan asked on April 2, 2024

    Hello, you need to fill the carbon first.
