Climate & Ventilation — Ø 150 mm

Ø 150 mm is the safest standard choice for a 120x120 and the entry point for a 150x150. The fan choice here is wide and runs from axial to centrifugal to mixed-flow, but what really sets this size apart is that you can buy a complete system from one manufacturer rather than assembling parts from several.

The size where AC Infinity is complete

On no other diameter is one brand this fully present. AC Infinity supplies the CLOUDLINE Pro S6 with a wired controller and the T6 with app and WiFi, the activated carbon filter and its XL version, the refillable carbon filter kit where you replace only the carbon, and the air filtration kits that supply fan, filter, ducting and mounting together. The PRO kit swaps the sliding controller for the Controller AI+ with its climate probe.

Or separate parts, with the widest choice of designs

To assemble it yourself, Vents has the broadest programme at this size: the VK as a centrifugal in several versions, the VKO as an axial with or without mounting bracket, and the TT as a mixed-flow. Alongside them sit the Can-Fan Iso-Max 150 at 410 cubic metres per hour, already damped, the Max Fan Pro 150 at 600 and the RK 150L at 760, plus Garden Highpro for a straightforward build with no control.

Fan and filter line up

There are carbon filters in this size, so you need no reducer between fan and filter. Allow for the filter costing airflow when you choose: a generous fan turned down runs quieter and more efficiently than the tightest one flat out, and that gap widens once a silencer goes on as well.

What this size does not have

Two things are missing at Ø150 and it is better to know up front. There is no Odor connect for dosing scent into the duct, and no duct heater. Both start at Ø125 and continue at Ø160. If you need either, that is a reason to put your whole run on one of those sizes.

Frequently asked questions

Ø150 or Ø160?
Building new, Ø150 gives you more fans and a complete AC Infinity system. Ø160 has more filters and more ducting. Pick one and hold it, because reducing between the two costs pressure.

Is this enough for a 150x150?
As an entry point yes, especially with a generous fan turned down. With a filter and a silencer on it and a room that runs warm, Ø200 gives you more headroom.

Kit or separate parts?
A kit if you are starting from nothing and want everything to fit for certain. Separate parts if you already own something or want a specific fan.
