AC Infinity CLOUDLINE T4 Product Review

The AC Infinity CLOUDLINE T4 4-inch inline fan comes with multiple speed settings with a 205 CFM. This gives you the flexibility to adjust the fan’s performance as need be.

Despite the various speed settings, the fan doesn’t hum or make any distinctly loud sounds, which is ideal if you are looking to be discreet with your growing.

It will make some noise, which is hard not to at the highest power setting, but not be so loud as to cause significant disruption.

An added feature of this fan is its lightweight design. It can be easily hung on the ceiling, or on top of a grow tent, which is useful for bigger grow rooms in particular.

Also included is an intelligent controller with temperature and humidity programming, fan speed control, timer, and alarm system.

As well as the above the AC Infinity T4 inline fan has a mixed flow design combined with a PWM-controlled DC-motor for truly quiet and energy-efficient performance.
