Solid and quiet

Reviewed in Canada on May 3, 2021

Verified Purchase

At first looks, this inline fan delivers. Firstly, it is significantly quieter than the less expensive counter part. It also moves a goodly amount of air through my carbon filter.

I believe that this product represents good value.

I fund that purchasing these items separately and, perhaps, from different manufacturers does save some money. Plus, you get to pick everything out yourself.

Solid product - gets the job done

Reviewed in Canada on May 19, 2021

Style: 4" fan Kit with Speed controllerVerified Purchase

I got the 4" inline fan and carbon filter combo, and it goes well with the 4x2ft grow tent. The combo is mounted to the top metal frame, and doesn't take up too much space. It's doing a great job filtering all the air and eliminating all the odour without making too much noise.

Super easy to set-up and I recommend this to anyone who is looking to get a fan/filter set up for their grow.

Good for a smaller tent

Reviewed in Canada on April 30, 2021

Style: 4" fan Kit with Thermostat ControlVerified Purchase

So I ordered this over an AC Infinity can which are great but this was the whole kit (fan/hose/filter) for almost same price so thought I’d gamble installed is a bit noisy(highest setting) but nothing to worry about using in a 4x 3 veg tent doing what I need it to do and running it on setting 2 temp is staying around 71 and humidity at about 45 with no humidifier just a light misting 2 x per day my intake is just a 4” hose that was left over from purchase. If I was using in a bigger set up I would buy the Infinity over this as a better build but for a veg tent is more than enough oh and I’m running a Spider Farmer led 1000w yea I could use a bigger light but only for veg

This one's a dud :(

Reviewed in Canada on May 16, 2021

Style: 4" fan with Thermostat ControlVerified Purchase

This unit is defective, the temp/humidity sensor doesn't work and the fan sounds like a jet engine. A bit dissapointed as I own a few Mars Hydro products and very pleased with everything so far...this one is a dud:(
Update: Contacted Mars Hydro and got a quick response. They offered an exchange but had already replaced the defective unit, got a refund no problem at all. I wouldn't hesitate to buy this unit again as I own multiple MH products and am very satisfied with everything else as previously posted... Customer Service is top notch👍

Amazing inline fan!

Reviewed in Canada on May 23, 2021

Verified Purchase

This inline fan is definitely a great value, and seems super durable as well. The base is actually a metal plate, which comes with mounting hardware, so you can safely attach this unit to whatever suitable surface you have.

The speed controller is on a separate wire, which is nice as you can place it somewhere convenient, especially when you have a small area to work with! At top speed this thing MOVES air, so even if you have a medium size tent, it should do the job its intended to do.

Style: 6" fan Kit with Speed controllerVerified Purchase

Well after having it for a while maybe four months, it’s just not doing what my other model does , same size as my other one from different company, if I turn my other one to 4, this one has to be up so high that the noise is driving me nuts…plus the build quality compared to you know who, it’s like a toy…I’m so sorry to come back and give terrible review, but maybe I can save someone else money, I packed it up , bought a new one from different company and it works amazing compared too?
Even the hose is so cheap , it’s well that’s enough…companies are trying to catch up to you know who..’.and there making terrible job cutting corners with cheap components…and don’t even get me started on the little size of the charcoal….oh boy…do your home work , don’t be stupid like me..I’m a pensioner with little money, to make a mistake is not good..oh well live and learn…
Happy growing everyone, and God Bless.

Works as good

Reviewed in Canada on August 19, 2023

Style: 6" fan Kit with Thermostat ControlVerified Purchase

Shipping was fast, the product came packaged very well and undamaged. Hooked it all up and everything worked as it should.

I have my controller setup on alarm mode so my fan constantly runs on 3 setting and bumps up to 10 setting when the tent gets too hot or humid. Its kind of hard to setup this way but it is possible! I do wish this unit displayed VPD measurements but for the price i cant complain.

Noise is what it is. I wouldnt want to sleep in the same room as it on 10 setting but its a 6 inch duct fan what can you expect. Its good in my books.

All in all this will be my first grow using this unit and im excited. The controller makes it super simple to regulate temperture and humidity inside the tent. The unit was easy to install and has plenty of extra wires and ducting to place wherever you want. I totally recommend this to whoever is in the market for a 6" duct fan.

This product is really great in built quality and work. It does its job perfectly. The only comment in can make is it should have longer cable for the controller.
