The 9 Best Inline Fans for Heating and Cooling Booster – 2019

An inline fan, or exhaust fan, is a fan that has internal ducting or is connected to ducting. The purpose of such a fan is to extract air, transfer it, or cool it down. 

Most inline fans are not in your ceiling or plasterboard but, instead, are in attics, roof spaces, or similar. They also feature in kitchens, greenhouses, and grow tents or rooms for those who are growing plants.

These duct fans replace ductwork and can either be hardwired into your home or plugged in. The hardwired variety needs a relay to your furnace, so they know when to turn on.

Given the sheer volume of inline fans for sale, it can take some time to work out which one is likely to suit your needs. You have to think about what you are using it for, how much you are willing to spend, and how large it needs to be. The airflow and noise are essential considerations as well. 

If the time has come to make a purchasing decision, then read on. These nine inline fans below may be able to help you choose the best one for your needs.

Considerations for Purchasing an Inline Fan

People use inline fans for many reasons. They are useful in kitchens, basements, greenhouses, industrial settings, and even grow rooms or tents. However, the fan in your price range won’t necessarily be the best one for your needs. It can take homework to establish your requirements concerning the fan’s capabilities. Read on to discover what those might be. 

  1. Installation Type    

    Every inline fan is different and can be installed in various ways. Think about what you need, then compare it to what a fan can offer. Some can be mounted on ceilings or walls, or hung wherever you need them. 

  2. Airflow Capacity

    Everyone has different needs when it comes to airflow capacity, and not all inline fans are the same. Pay attention the cubic feet per minute, or CFM, rating. This number will determine how fast the fan can circulate air. In a small space, you need one CFM per square foot for it to be effective. 

  3. Duct Size

    If you are replacing an old inline fan, then you need to consider the duct diameter to ensure a snug fit. Most are between four and 12 inches but can be in between or out of those measurements too. Failure to consider the duct size can result in a poorly fitting fan that doesn’t suit your needs.

  4. Price

    How much you pay for an inline fan can depend on what you get with it, the brand, and how large and powerful it is. You can’t choose the most affordable and hope it works. Instead, you have to match the fan to your needs, not your budget. 

    If you find a competitively-priced fan that has all the things you need, read the reviews. There might be a reason it’s within your price range. Don’t be afraid to rely on other people’s opinions of a product to help you make your final decision.

  5. Energy Efficiency

    No one likes a high utility bill, but that can be the reality if you aren’t smart with your purchases. Pay attention to the wattage and power usage of the fan you are considering purchasing. If you’re not sure, skim through the reviews and see if you can find anyone that mentions power usage – or excess usage.
