MARS HYDRO 4 Inch Inline Fan and Filter with Temperature and Humidity Controller, Carbon Filter, 33ft Length Flex ducting, 3 Duct Clamps

Great system, does what it says. Keeping a 180x120x60 tent cool and smell free. the app is really handy and once its all set up your temp and humidity can be automated pretty easily. tutorials on youtube are all you need for the controller or app, but would be handy to have a proper instruction manual for this in the box. Even in this size tent it sucks the sides of it in when its on full power, quiet but not the quietest, though its probably as quiet as it can be for its power. On low power its virtually silent. seems really well built and fits the tent nicely.

Cheap and worth the money

Excellent service, brilliant product well worth the money

Don't buy this broke after 2 week wont suck and making a buring smell spider farm alittle more but ppl say better tried messaging mars no answer

Can’t fault it. Easy to use and setup. I’ve had mine on 24/7 for 4 month now. Still no issues

Great product

Ambivalent to say the least. Currently considering a product return as the thing came with no usb dongle interface between the fan controller and sensor, without which it has next to no functionality. No separate power cable for the controller and no port on this particular controller to accept the sensor input. It may work ok. IV sent numerous cries for help over the counterintuitive and useless "instructions" but have not yet heard back. If the dongle I've grudgingly ordered doesn't deliver some function to this mess of wires immediately it'll be getting sent straight back and an AC Infinity system ordered in it's place. Update, pre dongle delivery . AI finally found I don't need the dongle to get the humidistat and temp readings working; merely to use a splitter provided but still without the dongle there is no easy viewing of the fan as a separate unit in the controller/app menu. Moreover the instructions were poor. App doesn't give easy access to better instructionals and those on YT feature controller 43 units with a different port configuration. Information support and instructions need refinement. Product may yet be decent.

no 12v power cable for the display trying to buy the right one now

Au top et silencieux

Exactly as described, great for our purpose.

Almost pulls too hard. Sucks the tent in but works great.
