Frequently Asked Questions
What is the difference between the single, twin and triple pack?
The twin and triple packs are two or three identical S4 fans in one order. Each one is the same AC-CCS4 as the single, so the specs match. The packs cost a little less than buying the same number of singles.
How much airflow does the Cloudray S4 give?
AC Infinity rates the S4 at up to 204 CFM and 29 dBA. It has 10 speed levels, so you can run it well below maximum when all you need is a gentle breeze.
What are the wind modes and oscillation settings for?
AC Infinity gives the S4 10 dynamic wind modes and 10 oscillation settings. The wind modes are designed to imitate a natural outdoor breeze instead of one constant stream of air. The oscillation settings change how wide the head sweeps, from a narrow area to wide coverage.
Can I control the S4 from the AC Infinity app?
The S4 is part of AC Infinity's UIS platform. With a compatible UIS controller you can use the AC Infinity app over WiFi for timers, schedules and climate triggers.
Can I run the S4 24 hours a day?
Yes. It has a miniaturised EC motor with dual ball bearings and is designed for long running hours in a grow tent. The listed life expectancy is 67,000 hours.
Is the S4 suitable for a humid grow tent?
Yes. AC Infinity gives it an IP54 rating, which covers dust and splashing water, so normal tent humidity is fine. Keep it out of direct spray and never submerge it.
How does the S4 compare with the S6 and S9?
The S4 is the smallest of the three, a 4 inch fan at up to 204 CFM and 29 dBA. AC Infinity lists the S6 at 325 CFM and the S9 at 405 CFM and 35 dBA. Choose by tent size and how much air you need to move. The S4 suits small tents and tight spaces.
