    • Great fan
Size: 4 Inch RJ12 Speed Controller
I have a 10x10 area wrapped in panda plastic and this fan on 30% will pull the plastic in. Air inlet opening is 6x4 inches. Works very well. If you are using it with a ac 5 or 10 controller make sure to upgrade the app and firmware the firmware is located in the setup of the controller.

    • Decent fan and filter, ducting leaves much to be desired
Size: 4 Inch RJ12 Speed Controller
Fan works well, moves a decent amount of air and isn't hugely noisy, filter is well built, the ducting diameter is smaller than the ends of both however and it takes great work to cut and work ducting to fit under rings but would easily fit INSIDE the openings on the fan but then there's no way to clamp on. ... show more

    • Economical kit but be warned, fan sounds like its failing. Filters already failed and wont scrub.
Size: 4 Inch RJ12 Speed Controller
Happy with the purchase but after three months of use the plastic inline fan sounds like its started to fail. I think one of the fins is loose? Unsure but makes odd sound. The inline charcoal filter DID fail! Not scrubbing at all. Reached out to Spider Farmer and haven't received an answer yet. Review will be updated once they resolve these issues. ... show more
