Is inline exhaust fan better?
The inline duct fan is the more powerful blower fan of the two that can move the most air. Given the difference in technology and applications, inline duct fans can deliver up to 1500 CFM using a 12-inch model. Duct fan boosters in comparison have up to 800 CFM of air flow power using a 12-inch model.
Is an inline fan the same as an exhaust fan?
The inline exhaust fan works the same way as the standard exhaust fan, but the design is different. The inline fan is mounted to a joist in the attic. One duct runs from the fan to a ceiling vent. Another duct runs from the fan to a roof vent.
How does a inline duct fan work?
The duct inline fan will be installed near a vent that is far from the blowing unit of the system. It adds mechanical air pull to the ducts at the desired vent. This helps draw air along the entire system and reduces the problem of the majority of air exiting at the closer vents.
Are inline fans better at pushing or pulling?
Inline fans are generally more effective at pushing air through ducting, as opposed to pulling air. Therefore, especially for long sections of ducting, position the fan at the inlet end, not the outlet (Fig 4.1).
Where should I put my inline fan?
Inline systems are popular as the motor is located in the roof space, making it quieter than a standard ceiling fan where the motor is directly above you. They can also be placed directly above showers.
Where should inline fans be placed?

What is the difference between ventilation fan and exhaust fan?
Differences Between These Fans The main difference between the two types of fans is their application. While a ventilation fan works to bring clean air into an enclosed space from an outside source, an exhaust fan removes pollutants from the indoor air in a home or commercial space.
How far can you duct an inline fan?
The maximum length for flexible ducting should be no longer than 1.5 metres for axial fans, 6 metres for centrifugal fans (up to 30 l/sec) and 3 metres (from 31 l/sec to 60 l/sec).
Is pulling or pushing air better?
If you're doing low speed fans pull is usually better, high speed favors pushing. But saying that it's a tiny amount of difference. You shouldn't have any issues and the best setup is whatever works in the build normally.
Is push pull necessary?
Push/pull is more necessary on thicker rads. You will see a benefit on rads of all sizes, but like everything with PCs, you'll see diminishing returns. Four fans on a 240 rad won't give you double the cooling as two fans on the same rad, but you will be able to run them slower and quieter.

The larger inline duct fans are, the more CFM they offer, but they’re also louder. But compared to the same size and capacity booster fans, they’re usually quieter.
How many watts does an inline fan use?
Where a typical inline fan consumes around 250 watts for the above-mentioned capacity, the duct booster fan consumes just 100 watts.
What is the difference between inline duct fans and duct boosters?
These differences determine the application scenarios for either of these fans. An inline duct fan’s primary application is to ventilate large volumes of space. On the other hand, a duct booster is employed where the existing HVAC system fails to deliver and distribute air uniformly, usually in-home applications.
