Generally, it helps resolve uneven temperature-related issues such as heating and cooling or cooling issues. It also performs essential functions such as heating, ventilation & air control.
The price of this kind of product is quite reasonable. You can easily pick them up at the market. But the challenge is knowing whether they will work or not.
A duct booster fan works excellently for home, office, grow room, and greenhouse usage. But sometimes, they don’t function effectively due to wrong selection and mismatching for your work.
This guide aims at helping you understand the kind of duct booster fan you need and whether the device will work for you.
So, let’s delve in.
Why Do You Need the Duct Booster Fan?
The booster fans for ductwork are effective solutions for everyday problems like high temperatures. It ensures air is evenly distributed in the room, thus maintaining the temperature. It also has an air pressure switch. Here are some why people use it:
To solve the uneven heat & cooling problem.
It is a common challenge that your house’s temperature will not be the same for every part. This situation is common in offices, greenhouses, grow rooms, etc. By using the duct booster fan, you can solve this problem.
This type of fan spreads the room’s air, reaching every corner of the room. So, during the hot season, the booster fan circulates the cool air in every part of the room and vice versa.
To maintain the HVAC of a room.
HVAC is an acronym for heating, ventilation & air conditioning. When you use the duct booster fan for your work, you can manage the HVAC quite easily.
These three conditions are critical factors for room environment management. A duct booster fan controls the temperature of the room air. You can use the fan as a suitable ventilator and control the ventilation system.

On the other hand, other processes of duct management are more costly than the booster fan.
The duct booster fan can complete the ductwork quite smoothly. If you want to manage your room’s HVAC in a low-budget and effective way, you may need the duct booster fan.
Why is the Duct Booster Fan Important for the Grow Room?
It is necessary for the grow room to maintain the ideal humidity, HVAC, and air balance. The grow room’s air factors are not controlled automatically. Therefore, you have to handle it wisely.
For this reason, the duct booster is the ultimate choice. Almost every grow room contains duct booster fans, which control the airflow entirely.
- The duct booster fan solves the uneven heating or cooling of the grow room.
- It functions as the exhausting system for the grow room.
- It helps to maintain the normal air pressure and flow of the plants.
- You can maintain the grow room’s humidity by exhausting or exchanging between the grow room air and the natural air. This is important for the grow room’s plants.
- It is an effective and money-saving device for the grow room.
How Does the Duct Booster Fan Work?
It is quite a simple process to understand. The duct booster fan has a strong motor that rotates at super-fast speed and increases airflow.
It has a power controlling system, motor controller, and fan blades. Some advanced duct fans have extra features such as a thermostat, remote control system, and other features.
The power controlling system ensures a suitable supply for the motor. The motor controller controls the motor’s speed. When the motor starts working, the blades rotate and increase the airflow. It also creates a low-pressure zone at the top of the duct. The air tries to maintain the static pressure and begins to move.
Different Types of Duct Fans and Duct Booster Fan Reviews
There are mainly two types of duct booster fans. They are registered as booster fans & inline duct booster fans. Read on to understand their differences and their mechanism.
Register Booster Fan
The register booster fan stays at the ceiling register of the room. You can also install it on the wall or floor—the installation process for this fan of simple and economical.
You can easily handle the rectangular register fan. It is only a plug and plays system to work. You can also add a remote control system, thermostat, etc. Nice and quiet.
The only disadvantage of the register booster fan is that it’s pretty noisy. It creates a lot of noise when it runs, which is discomforting.
We recommend ones with variable fan speed.
Inline Duct-Booster Fan
However, it is an excellent alternative for ductwork. The inline duct-booster fan is a cylindrical booster fan. It is a heavy-duty fan. It is advisable to place this fan between the HVAC source and the selected room(s). It produces less noise than the register fan. The rectangular fan also has a thermostat.
For the installation process, you may need an expert electrician. Because some hardware and wiring works are required, installing it in the right location is crucial.
