SystemAir – RVK SILEO Duct Fan
- Integral thermal contacts acc. EN 60335-2-80
- Can be installed in any position
- Inclusive mounting bracket
- Maintenance-free and reliable
- Well-known brand
- High quality
The RVK fan series is designed specifically for use in-line with ducting. The casing is manufactured from PA6 fibreglass reinforced plastic which offers minimal air leakage and a tough outer casing. Humid room applications of the fan are possible, thanks to the airtight casing and IP44 rated terminal box.
The fans have backwards-curved blades and external rotor motors. The mounting clamp makes it easy to install and remove, and prevents the transfer of vibration to the ducting or mounting surface.
Heritage: Systemair RVK fans have long been recognised as the industry standard. The fans utilise airtight casing, making them suitable for moving large volumes of humid air, essential for grow room applications.
Versatility: The fans can be fixed in any position (using the mounting clamp supplied) and come in a variety of popular sizes, in high and low-speed variations. All Systemair RVK fans can be used with a fan speed controller.

Your grow room needs fans all year round, no matter what the temperatures are like outside – they are always beneficial. They help with a variety of different problems that might otherwise arise and don’t just work to cool a room down. Ways they can help include:
- To Circulate the Air In Your Grow Room
- To Remove Excess Heat & Hot Spots
- To Control Humidity
- To Prevent Pests and Diseases
- To Control CO2
- To Circulate the Air In Your Grow Room
Outside, plants are going to encounter wind at some point. However, the wind never blows in the same direction for very long, and so you want to avoid having a static fan blowing. Oscillating fans and others that have movement are ideal for creating a more natural air circulation. You can place two fans in opposite corners to create a circulating vacuum of air.
To Remove Excess Heat & Hot Spots
Your grow room can easily get too warm depending on the conditions outside and within the area, you are growing. Grow lights emit heat, and whilst it may not feel like much to you, a slight increase in temperature can really affect your plants.
Some grow lights emit more heat than others but even with lights known to run cooler such as air-cooled lighting and LEDs, it is still wise to have fans blowing. They will help to keep the general temperatures lower and help with air exchange.
To Control Humidity
Another factor that can create problems in a grow room is humidity. Plants release water vapour throughout the day and this increases the humidity. If this level isn’t controlled, the growing conditions will decline.
A good ventilation system will help to wick away some of the water released during transpiration. This allows your plants to absorb more water and pull up nutrients through their root systems, which in effect helps with boosting growth.
To Prevent Pests and Diseases
Good air circulation will help to prevent pests and diseases taking hold. Stagnant and humid conditions are preferred of mould, powdery mildew, spider mites and fungus gnats. And we don’t want any of those to get in!
A steady breeze thanks to a few fans also makes it harder for the pests to establish themselves on the plants.
To Control CO2
Plants need outside air for one very basic reason: CO2. This is absorbed naturally throughout the day as part of a plant’s nutrient cycle. With a sealed grow tent set-up, the level of CO2 will gradually decrease, and this will limit growth.
Ventilation brings in the fresh air and fresh CO2 from outside whilst removing the old air from your grow room.
“Fairly quiet, and seems to move a reasonable amount of air. I’ve used it as a supplement to a cooker hood for a small kitchen, as the cooker hood is too noisy to use all the time. It seems to do the job fine. I expect it would also work okay for a bathroom to extract steam produced by a shower.”
“Replaced old cheap inline fan with this more robust easy to fit version. Always as an electrician in the past I bought the cheap everything included kits. Will not do that anymore after buying this fan.”
“This fan is great, very well made easy to install and very sturdy with great extraction rate and best of all it’s very quiet.“
