RVK CIRCULAR DUCT FAN

Description

RVK Circular Duct Fan is Systemair’s flagship inline extraction fan for grow room ventilation — a professional-grade centrifugal fan with a proven track record of reliable, high-performance airflow management in indoor cultivation environments. We have been recommending RVK fans to UK growers since 2017 as the industry benchmark for grow room extraction, combining robust construction, consistent airflow output and long service life in a compact, easy-to-install format.

The Professional Standard for Grow Room Extraction

The Systemair RVK’s reputation in the UK grow industry is built on decades of consistent performance. The externally rotor-mounted motor eliminates the internal mechanical losses associated with shaft-mounted designs, running cooler and more efficiently at all operating speeds. The backward-curved impeller blades are engineered to move high air volumes against the resistance of carbon filter and ducting back pressure without the efficiency losses that affect cheaper forward-curved designs — meaning your RVK delivers closer to its rated airflow in real-world installation conditions than most alternatives at comparable wattages.

Available in sizes from 100mm to 315mm diameter to suit grow rooms from a single 1m x 1m tent to large commercial growing spaces, each RVK model is rated for a specific airflow volume (m³/hr) and static pressure performance. Select your fan size by calculating the volume of your growing space (length × width × height in metres) and multiplying by your desired air exchanges per hour — typically 60 for standard grow rooms with carbon filtration.

Speed Control, Noise and Installation

RVK fans are compatible with standard triac-based fan speed controllers, allowing you to set the appropriate airflow for your system and adjust seasonally as ambient temperatures change. For noise-sensitive installations, the Systemair Isomax provides equivalent airflow in an acoustically dampened housing. Connect to your carbon filter and ducting using Fast Clamp connectors and flexible aluminium ducting for a complete, professionally installed extraction system.

Available in A1 (standard) and L1 (high-pressure) models — the L1 variant is recommended for longer ducting runs or systems with multiple bends where higher static pressure performance is needed to maintain rated airflow. A trusted and proven extraction fan for UK growers at every scale.
