Inline fans present an appealing alternative for homeowners who need to find the fan away from the room or rooms that need debilitating, but how much electricity does an inline fan use? Comparing 12-inch models, typical inline fans use about 250 Watts of electricity. Similarly sized booster inline fans in comparison use only about 100 Watts of electricity, but have significantly lower airflow capability overall.
How Much Electricity Does an Inline Fan Use?
Inline fans come in various setups, sizes, and capacities to meet a wide assortment of ventilation needs. They are accessible as basic single-port adaptors or flexible multiport units.
Single-port units have one incoming supply duct and one outgoing exhaust duct. Multiport versions have numerous channels with at least one inlet and one exhaust.
However, it’s important to note that booster inline fans use less energy in wattage than other comparable types of what we’d typically call inline fans. Looking at 12-inch models, for example, an inline fan utilizes about 255W while a booster fan utilizes just 96W (source).
Standard fans used for just ventilation units can use as little as around 6 watts for profoundly proficient models, while numerous standard units frequently use around 60 watts or more.
Context is very important here rather than just looking at the numbers and energy consumption. While an inline fan does use more electricity, it has its purpose. It moves air across a larger area of space and is meant to be seen as part of an overall HVAC system, while booster fans are more localized and targeted to one specific area.
How Power Use is Determined?
As a rule, power use is identified with airflow, estimated in cubic feet each minute (CFM) and the fan’s energy-proficiency. Some large limit fans or blend units with lights and radiators require considerably more energy usage. For instance, a warming unit on a fan may utilize 1,500 watts when the radiator is on; that is the reason blend units frequently have various switches for activity.

Types of Inline Fans
There are three essential inline fan types utilized: axial inline fans, centrifugal inline fans, and mixed flow inline fans.
Axial Inline Fans
Axial engine fans power more modest rooms, washrooms, and clothing storerooms — regions with a negligible distance of ventilation work between the channel and outlet. Hub inline fans take into account great air extraction at low pressing factors.
Principally utilized for homegrown applications, pivotal inline fans are great at moving air through ventilation ductwork that’s between 100 mm to 150 mm wide (which comes out to about between 4 to 6 inches wide).
The air conveying limit of axial inline fans goes from 100 to 500,000 CFM. Impellers generally have cutting edges with cross segments coordinating those of an aerofoil. When contrasted with bent sheet sharp edges, aerofoils can apply more prominent power to the air, in this way expanding the greatest pressing factor. They can keep up better proficiency over a more extensive scope of the volumetric stream.
Centrifugal Inline Fans
They are mostly utilized in messy airstreams (high dampness and particulate substance), material handling applications, and frameworks at higher temperatures. They can be little, with sub 0.125 kW engines, or massive, with many kW engines driving fans.
Due to the high pressing factor they make, centrifugal fans are ideal for high pressing factor applications, for example, drying and cooling frameworks. As the entirety of their moving parts is encased, they likewise have particulate decrease properties that make them ideal for air contamination and filtration frameworks.
Mixed Flow Inline Fans
Mixed flow inline fans join pivotal and divergent engine plans, making an answer ideal for fueling medium and huge rooms, mechanical laundries, and business restrooms.
These fans offer great wind current quality, just as prevalent pressing factor execution. Ideal for respectably long channel runs, curves, and Y branches, mixed flow inline fans offer the size and execution attributes given by pivotal and outward inline fans. They show centrifugal fan attributes from a size of 150mm upwards and axial fan qualities for sizes less than 150mm.
The power consumption of Mixed Flow inline fans ranges from 25W – 125W.

How many watts does an inline fan use?
These booster fans, or can fans, do consume less energy in wattage than their dynamic fumes fan partners, in any case. Contrasting 12-inch models, an inline fan utilizes about 255W while a booster fan utilizes just 96W.
Where should I put my inline duct fan?
For maximum use and efficiency, the best area to introduce an inline duct fan is 6 – 10 feet from the register you wish to support air. Insulate well to prevent air seepage.
Do fans use up a lot of electricity?
Running a fan takes significantly less power than running a climate control system. For reference, roof fans typically average at around 15-90 watts of energy utilized, and tower fans use around 100 watts.
Are inline duct fans worth it?
Inline fans are a less expensive option in contrast to replacing your pipe framework completely. While these fans range in cost from $30 to $200, they have also added maintenance charges. An inline fan is intended to supplant a part of ventilation work and is very commonly seen as part of the ductwork.
Inline duct fans (in one form or another) are necessary in certain areas of a home, like bathrooms, kitchens, and laundry rooms.
