Smart Air Filtration S4 Kit 4", AeroZesh S4 Inline Duct Fan with E12 Speed Controller, Carbon Filter & 8' Ducting, Cooling & Ventilation System for Grow Tents, Indoor Gardening, Hydroponics

I like the kit actually, but it has an issue I noticed within the second month of using it , the fan speed became slower than the first month even when i set it at the highest speed using the controller I keept usually between 7 and 9 , some times i u keep it in auto 12-12H

Chegou bem embalado, tudo perfeito, parabéns ao vendedor! Produto de alta qualidade

Good product

I've had mine almost 2 years I've had it on the number seven setting and it's never been off and still going strong

Variable speed controls allow for careful temperature and humidity controls. This is the cheaper model, but I already have a controller, so this setup was exactly what I needed.
