Frequently Asked Questions
What is in the AC Infinity Fan Favorite Duo B?
One Cloudray S9 9 inch EC clip fan (AC-CCS9) and one Cloudforge T7 15L humidifier (AC-CFT7), sold together as one set.
How is the Cloudray S9 different from the S6?
The S9 has a larger 9 inch impeller and moves up to 405 CFM at 35 dBA, with 10 speeds, 90 degree oscillation and 55 degree tilt. The S6 is a 6 inch fan at 33 dBA, better suited to smaller tents.
How big is the Cloudforge T7 and how much water does it use?
The T7 has a 15L tank and puts out up to 1300ml/h, with a maximum run time of up to 30 hours. The unit is 24.2 x 26.0 x 52.1cm, so check you have space next to your tent.
What size tent suits the Duo B?
The Duo B is aimed at medium to large tents and rooms that dry out in winter. For a smaller tent, the Duo A or Duo C may suit better.
How does the Cloudforge T7 control humidity?
The T7 has onboard humidity and VPD triggers using a corded sensor probe, plus timers and auto-start with backup memory. It also comes with an elbow nozzle and a five-way nozzle for directing the mist.
Is the Duo B cheaper than buying the fan and humidifier separately?
Yes. The set costs less than buying the Cloudray S9 and the Cloudforge T7 separately.
