The Systemair RVK Duct Fan is a high-performance centrifugal inline fan perfect for grow room ventilation. This quiet, reliable fan features an attached male IEC lead for easy connection to fan speed controllers. Ideal for carbon filters, it ensures optimal airflow and climate control in any hydroponic setup.
Maintaining the perfect environment in your grow room requires reliable, powerful, and efficient airflow. The Systemair RVK Duct Fan has been the benchmark for indoor gardeners and hydroponic enthusiasts for decades. Engineered in Germany, these centrifugal inline fans are designed to handle the rigours of continuous 24/7 operation while moving massive volumes of air with ease.
Built from glass-fibre reinforced polypropylene, the RVK range features a lightweight yet virtually indestructible casing. The backward-curved impellers are aerodynamically optimised to maintain high pressure, making them the ideal choice for pulling air through carbon filters or through long runs of ducting. Whether you need to exhaust hot, stale air or bring in a fresh intake of CO₂-rich air, the RVK series delivers professional-grade performance.
Key Benefits of the Systemair RVK Duct Fan
- Unrivalled Reliability: Specifically designed for permanent use, these fans can run 24 hours a day, 365 days a year, without losing performance.
- High-Pressure Impellers: The backward-curved blades are engineered to operate effectively even when connected to restrictive equipment like carbon filters.
- Plug-and-Play Simplicity: Unlike older industrial models, these fans come with an attached male IEC lead, making them compatible with most fan controllers (like the SMSCOM Hybrid Controller Mk2) right out of the box or plug in a female IEC lead and plug (sold separately) to get going.
- Airtight Construction: The reinforced plastic casing is airtight, preventing any odours or air from leaking before they reach your filtration system.
- Versatile Mounting: Every unit comes with a heavy-duty mounting bracket, allowing you to install the fan in any orientation (horizontal or vertical).
- Thermal Protection: Integrated thermal contacts with an automatic reset function protect the motor from overheating, ensuring long-term safety.
How to Use Your Systemair RVK Fan
- Power Connection: Locate the male IEC lead attached to the unit. Simply plug this into a compatible fan speed controller or a standard power outlet using an IEC to UK Plug adapter (both sold separately).
- Mounting: Use the included bracket to secure the fan to a wall or the frame of your grow tent. For even quieter operation, many growers choose to hang the fan using bungee cords to eliminate vibration.
- Ducting Connection: Slide your flexible ducting over the fan's flanges. Use duct clips or padded fast clamps to ensure a 100% airtight seal.
- Filtration: If using as an exhaust fan, connect the intake side of the fan to a carbon filter. Ensure the air-flow rating (m³/h) of your filter is equal to or higher than the fan's capacity.
PLEASE NOTE: 2m lead and UK plug sold separately, please remember to add this if needed.

Frequently Asked Questions
Can Systemair RVK fans be used with a speed controller?
Yes, all Systemair RVK fans are fully speed-controllable. To avoid any motor humming or buzzing at low speeds, it is highly recommended to use a transformer-based controller like the SMSCOM Hybrid Controller Mk2 rather than a digital dimmer.How do I wire a Systemair RVK fan?
These units come pre-wired with a male IEC connection. There is no need to open the junction box; you simply plug the lead into your power cable or controller.Which way does the air flow through the fan?
There is a small arrow embossed on the plastic casing of the RVK fan. This arrow indicates the direction of the airflow. Ensure this is pointing away from your grow space for extraction or toward it for intake.What size RVK fan do I need for my grow room?
This depends on the volume of your room. A general rule is to calculate the room volume (Length x Width x Height) and choose a fan that can exchange that air at least 20-30 times per hour.Example: In a 1.2m x 1.2m x 2m tent, the volume is 2.88m³.
2.88 x 60 = 172.8m³/h.
Adding 20% for the filter (172.8 x 1.2) gives you 207m³/h.
An RVK 125mm A1 (220m³/h) would be the perfect match for this space.SKU: 1379Systemair RVK Duct Fans
