Inline Duct Fan — Size & Kit Options
Build the airflow setup around your space instead of forcing one fan into every job. This black inline duct fan is offered in 4-inch, 6-inch, and 8-inch nominal sizes, with fan-only and kit configurations shown in the option menu. Choose the duct diameter first, then confirm the configuration and listing label before ordering.
For planned ducted-airflow projects
An inline fan sits within a duct run to move air between connected points. It can be considered for compatible ventilation, exhaust, or air-transfer projects where the duct path, intake, outlet, and power arrangements have already been planned. The housing is black ABS and the listing identifies an AC motor.
Airflow results depend on the full installation, including duct length, bends, restrictions, filters, grilles, and the way the system is assembled. Variant names help distinguish the listed choices, but they are not a substitute for checking the requirements of your project.
Choose your configuration
- 4-inch 180 CFM — fan-only listing option.
- 6-inch 380 CFM — fan-only listing option.
- 8-inch 720 CFM — fan-only listing option.
- 4-inch 180 CFM Kit — kit listing option.
- 6-inch 180 CFM Kit — kit listing option.
- 8-inch 180 CFM Kit — kit listing option.
The kit titles currently use “180 CFM” across all three nominal sizes. Because option wording can differ from the performance information supplied with the item, check the selected variant, package contents, electrical label, and included instructions before installation. Contact support if your project depends on a specific airflow rating.

Installation and safety
Installation requirements vary by location and application. Disconnect power before handling or maintenance.

Where local rules require it, use a qualified installer. Do not operate a damaged unit.
Product FAQ
Which size should I choose?
Match the nominal fan diameter to the compatible duct connection in your planned system. Do not choose by room size alone; duct length and restrictions also affect results.
What is the difference between fan-only and kit options?
The listing offers both types, but package contents can vary by selected variant. Confirm the option name, product images, and supplied packing information for the exact choice.
Why do the kit names all show 180 CFM?
That is how the current variant labels are presented. If a specific airflow figure is essential to your project, confirm the selected variant information before ordering or contact support.
Can I use it with any duct run?
No. The duct diameter, route, restrictions, electrical conditions, and installation method all need to be compatible with the selected fan.
Does a larger diameter always mean better airflow?
Not automatically. The entire system affects performance, including bends, filters, grilles, duct length, and installation quality.
Who should install it?
Follow the supplied instructions and local requirements. Use a qualified installer whenever the electrical or building work is outside your experience or local rules require one.
