Spider Farmer Air Filtration Kit 4 Inch, Inline Duct Fan with RJ12 Speed Humidity Controller, Carbon Filter Combo, 13 Ft Ducting, Ventilation System Kit for Grow Tents, Hydroponics, Indoor Gardening

Product was just what I needed! Works great at cooling down my grow room. Would defiinitely recommend!

What a great purchase, such an easy, quick setup. Would totally recommend to anyone. Would definitely buy again.

Switched to spider farm products this year and was stoked on the quality. Adjustable speed and quiet even at the highest setting.

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.

I purchased this for my Laser Engraver for the smoke... yeah it didn't workout for me on that, the smoke went right through the filtration canister... I'll probably use it for my molds and casting system... I'm still ok with it!

On the very first day, the fan was making noise on low speed. Kind of a strange hum. I ran the fan 24/7 on high, which doesn't seem to flow that strong. Later one night it starting making a horrible racket, the rear bearing went out. Motor seized up. I'm glad I was right there when it happened, it could have overheated and started a fire. Do yourself a favor and buy a fan one size bigger than you need. Most have variable speed fans so you can dial in the volume of airflow you want. Just my opinion.... REVIEW UPDATE!!! Customer service contacted me about the fan. They sent me a replacement fan ASAP. I wish all companies cared about their customers like this. I will definitely be purchasing from them again. Thanks Spider Farmer.

This exhaust fan works amazing. It keeps my temp perfect.

Easy to set up for beginners even. I have mine both on the outside of the tent to allow for more room for the plants and light. Top notch system! My humidity and temp are perfect. Grab one of these on a sale it’s well worth it

De slang gaat niet direct op het filter helaas dit is net te krap waardoor de slang scheurt maar verder werkt het prima.

This works perfect!

À première vue, le produit semblait de bonne qualité : propre, bien fini, rien à redire visuellement. Mais une fois branché, j’ai découvert qu’il était défectueux : impossible de régler la vitesse correctement, le ventilateur tournait trop fort et ne réagissait pas au variateur. J’ai contacté la marque, qui m’a renvoyé un autre ventilateur. Et là, c’était encore pire : le modèle reçu était sale, avec des traces d’usage, et il ne fonctionnait pas du tout. Très déçu de l’expérience. Le produit pourrait être bon, mais vu les défauts et le remplacement inutilisable, je ne recommande pas.

Toller Rohrventilator;sehr leise im Gegensatz zu anderen! Günstig nicht überteuert für das ganze Set!

Easy to set up, I’d say it is pretty silent but I have it hanging from the shed ceiling using the anchor winches, which come with it. Seems fairly powerful, quality is really good and it does seem to pull smells into it, stopping upset neighbours, but time will tell with that! All in all I am very impressed with this fan so far.
