When you're putting together a small ventilation ducting air distribution setup, the first decision is often not about airflow curves - it's about whether a compact AC fan will fit your space and your wiring plan. The AC Infinity LS8038-X Roof Fan Kit is a new, AC-powered muffin fan with a small footprint and a low cost, making it a natural candidate to think through.
Quick verdict
If your project needs a small AC-powered fan for a tight ducting run, the LS8038-X is a concrete option at USD 8.95. It's a black 3.1 x 3.1 x 1.5-inch kit with a 2-pin power connection, sold new in box as a muffin fan. This is a component-level airflow solution, not a whole-room ventilation unit.
Who it suits
This fan suits a DIY-minded shopper who wants a compact, basic airflow component for a narrow duct or an equipment spare. The product title positions it as a roof fan kit for ventilation equipment, and the fan was bought new to serve as a spare for a fireplace heat exchanger project. If that matches the scale of your setup, the LS8038-X fits naturally.
What stands out from the listed details
- New compact size: The title says "NIB" (new in box), and the stated dimensions are 3.1 inches long, 3.1 inches wide, and 1.5 inches high, so it can fit in tight spots.
- AC-powered operation: It uses AC power, which is a clear fit for AC-based ventilation setups.
- 2-pin connection: The 2-pin power connection is specific and worth matching to your existing wiring before you commit.
Meaningful trade-offs
The biggest trade-off is size versus duty. A 3.1-inch square fan with a 1.5-inch depth moves air in a localized path; it is not built to push air through long ducting. That doesn't make it wrong - it just means the LS8038-X is best for short, direct runs or as a spare in a heat-exchange assembly.
The 2-pin connection is another detail to weigh. If your setup already has a matching connector, great. If not, you'll need to sort out the connection yourself.
AC Infinity LS8038-X Roof Fan Kit
The strongest reason to choose this kit is that it is a new, compact AC muffin fan. The limitation is that the 2-pin connection and 3.1-inch size tie it to smaller, direct-airflow projects rather than broad ducting work.
Bottom line
The AC Infinity LS8038-X Roof Fan Kit is a sensible pick when your ventilation ducting task comes down to a small, AC-powered muffin fan at a low cost. It gives you a 3.1-inch footprint, a 2-pin connection, and a clear spare-parts purpose - as long as you're comfortable working with a compact component rather than a full blower system. If that's your project, the $8.95 price makes it easy to say yes.
