RADAIR MIXED FLOW INLINE FAN

Description

The Radair Mixed Flow Inline Fan is a professional mixed-flow extraction fan that combines the quiet running and static pressure handling of centrifugal fans with the high flow rates of axial fans, producing a fan that handles the back-pressure of carbon filter installation — the most common application in grow room extraction — while maintaining the low noise signature that makes it suitable for noise-sensitive growing environments. Mixed-flow technology is the professional choice for grow room extraction because it delivers real-world performance that simple axial fans simply cannot match when connected to a loaded carbon filter.

Mixed Flow Technology and Why It Matters for Grow Room Ventilation

The difference between axial and mixed-flow fans is fundamental in grow room extraction. Standard axial fans — the type used in computer cooling and basic ventilation — move large volumes of air efficiently against low resistance. Connect them to a carbon filter with its inherent restriction to airflow, and performance drops dramatically as the fan struggles against the static pressure. Flow rates measured without a filter can be two to three times higher than what the same fan delivers with a filter attached. Mixed-flow fans are designed around an impeller geometry that combines axial and centrifugal airflow components. This hybrid design maintains flow rate under the kind of static pressure that a carbon filter creates, delivering genuinely usable performance in real extraction system configurations rather than the optimistic free-air figures that axial fan specifications often represent. At The Horticulture Company we always recommend mixed-flow or centrifugal fans for any extraction system that includes a carbon filter. The Radair mixed-flow range delivers this professional performance at competitive price points accessible to hobby and professional growers alike.

Speed Control and Compatibility

The Radair Mixed Flow fan is compatible with standard EC fan speed controllers that provide 0–10V or voltage reduction control. Reduce fan speed during cooler periods or when maximum extraction is not required. All standard flange sizes are available to match common ducting diameters used in UK grow rooms. Connect to CAN-Filter or CAN-Lite carbon filters for a complete, effective odour control system.
