Things You Should Know To Choose The Quietest Inline Fan

quietest inline fan

You need to know six factors beforehand when choosing inline fans: carbon filters, humidity, heat from lighting, noise, and power rating. Therefore, selecting a quality and suitable inline fan is essential. It's best to have a better view of how to utilize an inline fan first. Below are some criteria you can take a look at to choose the quietest inline fans for you.

Carbon Filters

Especially when you are planning to install the inline fan for growing plants, it's very noticeable that the smell inside your grow area will sometimes be a little too much for you. Therefore, you will need to look for a way to help srub the scent.

Fortunately, the carbon filters that are usually mounted on every inline fan will help you with that. The filters’ sizes will depend on your needs of how many plants you're planning to grow. 

quietest inline fan

Humidity

When it comes to farming, the worst nightmare that growers often come across is fungi and mold. The fungus can wipe out your stable within a few weeks, while a mold is challenging for you to notice until it's too late. The leading cause of fungi and mold outbreaks is humidity, and your defense tool is now the inline fans, which have good quality to battle against the humid room.

To have a clear view of the suitable quietest inline fans for you, you need to glean the information from the following two factors. Is the region that you live in prone to high humidity? And what season is it in your area? 

quietest inline fan

Especially when it comes to growing, the air inside your growing tent will become moist and stagnant if it isn't vented the right way. And if the situation continues for a long time, it can have harmed your plants. To minimize the chances of disease on your plants, the overall humidity needs to be lower by continually circulating through the grow room of fresh air.

Heat From Lighting

When you plan to use this inline fan in farming, there's one thing you need to notice that your grow room will require a large amount of light to develop. That means the heat inside will increase drastically and results in death for your crop.

The quietest inline fans have good quality will help exhaust the hot air from the room like the way regulators do. And then, they help bring in cooler air. 

Before any hot heat can badly affect your plants, your inline fan will quickly exhaust all of your space. And to help your inline fan do that better, you need to determine the power requirements beforehand. The lighting that you choose will also impact the power requirements of your inline fan. 

Noise

When buying an inline fan, the most significant factor you need to consider is the inline fan’s noise. You will need to require the quietest inline fan for your benefit and other people nearby unless you are lucky to live around with people who don't have the idea of complaining about the noise that the fan will produce.

You may think at first that it doesn't matter if it makes a loud noise. But we sure that you will reconsider if you hear the sound that a 12 inches inline fan makes when it works at its full power.

quietest inline fan

Fortunately, on the market today, most inline fans are quiet. But the more silent the inline fan, the better. And some manufacturers even design their inline fans with special housing to lessen the decibel output.

Power Rating

The power rating is another necessary aspect you need to consider when buying an inline fan. It is usually presented in Cubic Feet Per Minute (CFM).

To have a basic estimate of the CFM requirement for your installing area’s CFM requirement, divide the room’s total cubic feet by 3. The total cubic feet will be counted by measuring the room’s length, width, and height, and then multiply these three numbers together.  

It will be a disaster if you realize that it is too weak to exhaust air effectively after purchasing the inline fan. Therefore, understanding the CFM requirement is essential before you decide to buy anything. As a general rule, if your inline fans are added extra items such as heat from lighting, carbon filters, and ducting, the CFM requirement will increase.

quietest inline fan

Size

The size will be a detail you need to notice to calculate how much air you need for your area, primarily if you use the inline fan for farming. Of course, a compact closet space will need a different size inline fan than a large grow tent. 

You should measure your space first and then draw a clear vision in your mind where to put the inline fan for the most beneficial result. It's never a waste of time to account for every inch of the space - we believe you won't want to purchase an expensive inline fan that can not fit into your area.

Typically, there are some options for you to choose to install the inline fan: attached to the ceiling in the room, on the floor, or hand outside the room. 

You will see many size options when searching for an inline fan online, usually varying from 4 inches to 18 inches industrial-grade inline fan. To purchase the appropriately sized one, it's vital to have a clear vision and carefully measure your room’s size, as different people will choose a large-sized or a small-sized one if they think it will be a waste of energy for a bigger one.

Conclusion: My Top Pick For Quietest Inline Fan

As you can see from our review above, the quietest inline fan significantly impacts maintaining a healthy and ideal environment for your area, no matter what place you plan to use. You will have a peaceful mind knowing that your air is always ensured to be cool and fresh when you decide to buy the quietest inline fan instead of other expensive air conditioning. You shouldn't underestimate the inline fans’ job, as they help a lot in exhausting air and pushing air to the outside through lighting, ducting, and the carbon filter, which is very useful for your farming.

Here are our top 5 picks of the quietest inline fan that we have created based on the most efficient feature to help you choose the quietest inline fan successfully.
