What Exactly is a Booster Duct Fan Used For?

First things first - what is a booster duct fan, exactly? We recently wrote an article breaking down how inline duct fans work - but booster fans operate a bit differently, as the goal is different.

A booster duct fan is designed to increase airflow through your existing ductwork. This is typically done because the ducting is too long for the installed fan to adequately pull/push air. Or, maybe there are too many elbows and turns throughout the ducting, causing more drag and compromising on airflow. Sometimes, the problem is caused by the central AC/furnace being located too far from the room in question.

Either way, the booster duct fan focuses on addressing this problem - which is where the name "booster fan" comes from. Because of the long duct runs or high quantity of elbows in the ducting leading to the remote room in question, the output of the central AC or ventilation system is not sufficient to push enough air all the way to a remote room.

Instead of revamping the system altogether, you can rely on a booster fan as a simple, affordable means of delivering more air to the remote rooms in the house or building. There is no need for reworking the existing ductwork, or worse - replacing the furnace or HVAC system altogether (despite what the HVAC company you've been working with has recommended). You can save money and make the space more comfortable at a fraction of the cost.

The kicker, though, is that you need the best booster duct fan to make this vision a reality. Let's talk about a few problems you can avoid by investing in top quality from the start.

Why You Need the Best Booster Duct Fan

When we tell you that shopping for a quality booster duct fan isn't something you should take lightly, we mean it. Subpar fans will not get the job done as intended. If you don't have enough airflow in your space to begin with, a lower-quality booster duct fan will not magically create more airflow - it will just move the same amount of air around more slowly.

The second reason has to do with energy efficiency. When you use a lower quality booster duct fan, two things happen:

  • The motor works harder than necessary to try and move the desired volume of air
  • Airflow is often still insufficient even with the motor working overtime

This combination means that you'll be using more energy than necessary to heat or cool the space - and likely won't even achieve the desired results.

The third reason to invest in the best from the start is longevity. When you try to save a few bucks going with a more affordable booster fan, you end up paying more, in the long run, to replace the fan early or get it serviced.

Ultimately, it just makes far more sense to invest in a quality product that will do the job right - which is where TerraBloom comes in. Keep reading to learn what separates our products from the competition!

What Separates the Best Booster Duct Fan From the Rest?

Now that we've talked about why you need a quality booster duct fan, let's focus on what separates the best from the rest.

There are so many different ratings and buzzwords around ventilation components. But really, your shopping considerations can be boiled down to the following factors:

Precise Adjustment

You need a fan that can be adjusted with precision to run at lower speeds. Our recommendation is to typically size up on the CFM you need and run the speed at a lower setting. This dramatically cuts down on the background noise and humming experienced. So, you obviously want a fan that can be paired with an inline fan speed controller for this.

But, you should also take note of the motor being used within the booster fan. EC motors are the latest and greatest in the industry, and you should stick with one of these over an AC motor. EC motors can be optimized with just a simple controller - while AC fans need more complex, expensive controllers (variarc/triarc styles).

Compact to Fit Any Location:

Another consideration to keep in mind is the size and stature of the booster fan. Because these need to work within your existing ductwork - and typically, are placed within small confines - you need a compact fan to fit any location.

It can be tricky to reach certain spots in your attic, basement, or crawl space - so make life easier on yourself with a compact fan that still delivers impressive airflow boosting properties.

Effortless Automation

Of course, you need the fan to work without you telling it to. You need your fan to turn on and off with the HVAC system so you're not wasting energy or lifespan unnecessarily.

For this, you'll want to seek out a booster duct fan with effortless automation capabilities. This is doable - but only with the right fan. With the recommendation we'll provide in the section below, you can wire the power supply to the fan through the furnace/AC with ease. Or, use a thermostat speed controller which would “feel” the increase or decrease of the temperature in the ducting and start the fan.

Independent Testing, Dependability, & Peace of Mind

There are a few other factors you can look for to determine whether you're truly getting the best booster duct fan or not.

For example, look to see what kind of independent testing has been done on the fan. Many manufacturers do their testing internally - leading to skepticism about the ratings they claim. Instead, we test our fans independently through HVI and Energy Star. You can trust that everything we claim is backed up by fact - and you don't just have to take our word for it!

You also need a fan that you can depend on to operate efficiently for the long haul. This is the type of purchase you want to make just once for your home or building - and then, never think about it again. One way to enjoy peace of mind in this regard is to ensure the fan you're buying comes equipped with a warranty - protecting your investment in a sense.

Now, with all this said - you're ready to start shopping for the best inline booster duct fan for your home, building, grow space - or any other application. But we're going to make life even easier on you - by pointing you in the right direction below. Allow us to introduce you to TerraBloom Booster Duct Fans: the best choice for you!
