Systemair RVK Inline Fans
Systemair's RVK is a mixed-flow inline fan that's been a quiet standard in ventilation for decades, well before hydroponics adopted it. We stock it from 100mm through to 250mm, and the appeal is consistency rather than any standout feature, it runs at a predictable noise and airflow level across its whole size range, which makes it easy to size correctly for a tent without second-guessing the spec sheet.
If you're running a Systemair RVK with an EC-rated variant, it pairs directly with GAS EC2 or EC5 fan controllers for speed control and balancing. For a standard AC version, the JB Fan Speed Controller handles manual speed adjustment instead.
Frequently Asked Questions
What size RVK fan do I need for my tent?
Match the fan's rated airflow to your tent's volume and add some headroom for your carbon filter and ducting length, both reduce effective airflow from the fan's maximum rating.
Is the RVK fan loud?
It runs at a moderate, predictable noise level for its size, not silent, but not the loudest option either. Pairing it with a speed controller lets you run it below maximum speed for quieter operation when full airflow isn't needed.
