Global Air Supplies RadAir Mixed-Flow Inline Fan — High-Pressure Extraction at Entry-Level Price
Best for: New growers needing a reliable, high-pressure extraction fan that handles carbon filters and longer ducting without breaking the bank
Our thoughts
RadAir punches well above its price point. It's a proper mixed-flow fan — the kind that maintains pressure even when you're running it through a carbon filter or a decent length of ducting — at a cost that makes sense for beginners. Plug-and-play, well-made, and does exactly what it should. One we sell a lot of for first-time setups.
The Global Air Supplies RadAir is a mixed-flow inline extraction fan designed to move large volumes of air whilst maintaining high static pressure — the kind of performance you need when you're filtering air or running longer ducting runs. Available in six sizes from 100mm to 315mm, it's the kind of workhorse fan that new growers rely on, and experienced growers buy when they don't fancy paying premium brand prices for the same functional outcome.
How it compares
RadAir occupies a clever middle ground in the inline fan market.
-
vs. budget axial fans (HighPro, etc.): RadAir is mixed-flow, meaning it generates real pressure even when loaded with a carbon filter. Axial fans drop off hard under resistance. You're spending the same money but getting a fan that actually works when you need it to.
-
vs. premium brands (RVK, Can-Fan, Vortex): You lose the industrial warranty and whisper-quiet operation, but you keep the core performance. Same mixed-flow engineering, significantly lower cost.
-
vs. smart fans (AC Infinity CLOUDLINE): No app integration or brushless motor, but no subscription nonsense either. This is just a fan that extracts air reliably.
In plain terms: you're getting mixed-flow technology — superior pressure handling — at an axial fan price point.
Usage guidance
RadAir is flexible enough to work across different extraction setups:
Carbon filter extraction
This is where RadAir earns its keep. A carbon filter will reduce airflow by roughly 25% on its own. With RadAir's mixed-flow design maintaining pressure, you still get usable extraction rates. Mount the fan inline between your ducting and the filter, or after it — either works.
Direct ducting extraction
No filter, just pulling stale air out of the space via ducting to outside. RadAir handles this cleanly. Shorter ducting runs mean better airflow; every metre of duct reduces performance, so keep runs tight where possible.
Installation and mounting
Plug-and-play. IEC socket connection direct to mains or via a fan-speed controller. Integral mounting bracket included; many growers prefer to hang the fan from bungee cords instead, which cuts vibration and noise. Simple as that.
Ducting best practice
Keep bends swept and gentle, not sharp right angles — they kill airflow and add wind noise. Size your ducting to match the fan outlet (100mm, 125mm, 150mm, etc.) and don't overstretch. Ducting constrictions choke performance faster than anything else.

Who this is for
- First-time growers building a basic extraction setup for the first time
- Anyone upgrading from an undersized axial fan that can't handle a carbon filter
- Budget-conscious growers who want mixed-flow performance without premium pricing
- Hobby setups where equipment costs matter and reliability is non-negotiable
- Anyone running multiple spaces who needs to spread costs sensibly
Particularly well suited to spaces where extraction needs to work reliably day in, day out without fuss or noise complaints.
Our take
RadAir is proper kit at a price that actually makes sense. It's not the quietest or the smallest or the smartest, but it does the core job — moving air under pressure — with the kind of consistency that earns repeat customers. The mixed-flow design means it handles filters and ducting without petering out, which is exactly what you need from an extraction fan.
If you're setting up for the first time or replacing something that's struggling under a carbon filter load, this is worth picking up while clearance stock lasts. Does exactly what it should, every time you switch it on.
