Recently, I have run into a lot of questions from my friends and fellow growers on the best 8 inch inline fans. The questions all boil down to the best 8-inch inline fan as there are so many out there.
One friend talked about purchasing two fans consecutively where they did not last for six months cumulatively. Such incidences are so saddening, and since I have the knowledge and experience with 8-inch inline fans, I thought, why not help fellow growers and people who may need air exchange in their spaces.

Why do I need an 8 Inch Inline Duct?
At the beginning of this review, I talked about the inspiration of writing it being my grower friends who have had numerous questions on inline ducts and the best ones.
This does not in any way lock out people who are not growers from using inline ducts. First, let me address those individuals who have to grow tents and wonder how the 8-inch inline fan will be helpful and why they need it.
Most grow rooms and tents are in enclosed places or at tight quarters. This may cause overheating of the grow area, whose consequences are the plants’ death- a loss to the grower. This is where the 8-inch inline fan helps ventilate these grow areas creating conducive environments for the plants to thrive.
This brings me to the next common question, why do I need an 8-inch inline duct if I am not a grower? Well, you need the 8-inch inline duct fan for your space, whether it is a grow tent or not.
This is because it is only healthy to live or occupy even temporarily in well-ventilated spaces. Poor ventilation in rooms makes them ‘sick.’ You can only expect someone living in a ‘sick’ room to be a patient.
The symptoms of sick rooms include the growth of molds as a result of condensation. Consequently, the occupants may develop a wide array of respiratory illnesses, which again calls for unnecessary hospital visits.
Further, it is hard to quantify the amount of loss that ‘sick spaces’ would bring to the equipment and space fabric. Poor ventilation causes the condensed air to damage walls, fabric, and various equipment that cannot handle high humidity levels.
It’s saddening to imagine that the mere lack of an 8-inch inline fan in your spaces can cause all these losses. The good thing is that for you, the reader, this is only an imagination since you now have all the resources necessary to purchase an 8-inch inline fan of your choice to facilitate airflow in all of your spaces.
Your treasured health, that of your pets, and also spaces will now be safer than ever from the consequences of poor ventilation.
Safety Tips When Using an 8 Inch Inline Fan
The first time I got ahold of an 8-inch inline fan, I was so proud of myself (it comes with purchasing something you have saved up a lot). However, the fears started trickling in soon after the easy installation of the fan.
How will I ensure that this inline fan does not cause harm to anyone within this space? I am sure that this is a worry that most people contend with since no one wants tragedy from a device they have brought within certain spaces.
This experience prompted me to write safety tips when one has an 8-inch inline fan within any of their spaces.
The first and most important safety tip that I have found is to keep it away from the reach of children. Well, I agree that children are little blessings, but at times, they can be little terrorists wanting to experiment with anything they find, even as old as in their adolescent stages.
This inline fan should be kept away from their reach since it is easy for them to interfere with the cords or the blades, leading to accidents and destruction to the inline fan.
After purchasing the equipment, ensure that you do not throw away the manuals. Inside the manuals, there are product safety symbols. As part of the safety tips, look at these symbols and understand what they mean to not act against the instructions and cause harm.
Still, as part of safety tips, do not attempt to touch the blades. These may cause injury to the fingers and cause the fan to break down.
The other safety tip is to keep a maintenance schedule. This is something that most people overlook. However, it is important as inline fans may develop problems over time, such as trapping dust over long periods.
This may affect the functioning of the motor causing operational noise, which is quite disturbing. Occasional maintenance also ensures that there is the identification of any problems before they can wreak havoc in your spaces. It is tempting for individuals to disassemble the inline duct fan once it is faulty.
However, refrain from this if you are not a professional. It is not safe, and you may be endangering your space with all that is in it. I would advise that you call a professional electrician to determine the problems.
Although this may cost you the option of doing it free for yourself, I think it would be better to be safe than sorry when the damage is done to your space due to unprofessional intervention.

The intelligent component of any device means that there has to be some memory capability, and this fan is no different.

It’s a worthy investment, so price should not be an obstacle.

This calls for an inexpensive option due to the budgetary restrictions, which is the first advantage of this inline fan. It has reasonable pricing. On top of this, it has a permanently lubricated bearing taking off the burden of constant lubrication (it’s a headache for most of us).
This fan is also light in weight, making it easy to change positions in your spaces. Quiet operations should always be on top of the list when looking for inline fans because noise can drive you crazy. Fortunately, the Vivosun 8″ Inline Fan is whisper quiet and also energy efficient.
The drawback of this equipment is that it has a short power cord presenting a challenge when connecting it with ease. Further, if you need to use your inline fan with a carbon filter, this device will limit you. It is not powerful enough to support carbon filtration.

Let me start this review with an exciting feature of this device- it comes with a 10-year warranty. Most of us feel safe when purchasing products with a warranty because it serves as a kind of assurance that there are chances of longevity.
Although we might never use the warranty for this device because of its capabilities and durability, it is always good to have a warranty assurance.
The inline fan is also energy efficient, enabled by the ac brushless motor powers with dual impellers. An energy-efficient fan is the dream of every grower, so you should not have to be left behind.
Although this inline fan does not have ultra-quiet operations, the noise is at a manageable level. This comes from its double insulated walls allowing you to go about your work without crazy humming noises from the fan.
This review is all about honesty, and in that spirit, I would like to mention the only drawback that I have come across for this device. The brackets for mounting the inline fan are plastic.
This makes it quite a challenge in installation as most people will fear the inline fan’s weight could take the brackets down any time. Even if the brackets were to mount well, they do not last long, forcing the user to buy metal brackets.
- Energy efficient
- Ten-year warranty
- Quiet operations
- The bracket system is plastic.
