Can-Fan are one of the original names in grow room extraction, and the reason people still ask for them by name is noise. The Isomax and Q-Max are built as acoustic units rather than a bare inline fan with insulation added afterwards.
The range
- Can-Fan Isomax – silenced acoustic fan, the quiet option for a flat or a bedroom.
- Can-Fan Q-Max AC – silent AC fan with high static pressure, so it holds airflow through a loaded carbon filter.
- Can Silencer – inline muffler for the duct run – see silencers.
- Isomax + CarboAir extraction kit – fan and filter matched and bundled. See extraction kits.
- Fan controller replacement probe – the spare people always need eventually.
Static pressure, not just airflow
A fan's headline m³/h figure is measured with nothing attached. Put a carbon filter and five metres of ducting on it and a weak fan collapses. Q-Max and Isomax are built for that resistance, which is why they hold their airflow where cheaper fans do not. It is also why undersizing on the headline number is such a common mistake – see extraction fans for the sizing guide.
Note on the name
Can-Fan and CAN Filters are related but listed separately here – the filters are on CAN Filters. Pair either with ducting pulled taut, not concertinaed.
