Phresh Hyperfans have earned their reputation as one of the market-leading EC duct fans. The V2 builds on the popular V1 with a new 9-pole brushless motor (up from 7-pole), delivering more airflow and static pressure under load — with filters and ducting fitted — while running noticeably quieter.

CarboAir's coarser, higher-quality carbon avoids that trade-off, giving strong odour scrubbing without stifling the fan's output.Which Size Do I Need?Work out your grow space volume in m³ (Width x Length x Height), then multiply by 60 to get the air movement needed per hour to fully refresh the room every minute. Multiply that figure by 1.5–2 to account for bends in ducting, heat, or anything else that restricts airflow.It's generally better to over-spec your fan and dial back the output with a controller — this gives you headroom for hotter months and future-proofs you if you upsize your grow room later. Running a fan at 100% around the clock also shortens its lifespan; 60–80% is a healthier long-term target.Note on ControllersThe Hyperfan v2 comes with its own manual speed dial. If you want to connect it to a Global Air Supplies fan controller instead, you'll need the Pack 16 adapter cable.
