When you're working through ventilation ducting air distribution, the fan that actually moves the air is the piece that decides whether the system works. The AXIAL 8038 LS8038-X Roof Fan Kit is an AC-powered muffin fan offered at USD 8.95. It's listed as new in box (NIB) and was originally bought as a spare for a fireplace heat exchanger project. That backstory explains why a compact, no-frills fan like this one is available.
Quick verdict
The AXIAL 8038 LS8038-X is a small muffin fan that fits the kind of spot where a full-size duct blower won't. If you're adding airflow to an equipment cabinet, a small vent, or an enclosure, this fan deserves a place on your shortlist.
Who it suits
This fan is a practical match for localized ventilation tasks, such as a roof vent or a heat exchanger enclosure, where space is tight. The original intended use was a fireplace heat exchanger project, so that's a reasonable starting point. If your project has a confined area, the 3.1-inch height and length and 1.5-inch width are the dimensions to check.
What stands out from the listed details
Two details stand out: the 2-pin connection and the AC Infinity branding with a black finish. The model designation LS8038-X appears in the title, and the stated condition is new. The fan's compact, no-frills design matches the modest scope of its intended use.
Meaningful trade-offs
The compact frame is the main trade-off. This muffin fan is designed for confined spaces, not long duct runs. It won't replace a higher-capacity duct blower for whole-house distribution. If you need a fan for a small spot, that's fine; if you're planning a major duct renovation, look for a larger unit.
Bottom line
If you need a compact fan for a small ventilation project, the AXIAL 8038 LS8038-X is a straightforward pick. Its small footprint and new condition make it a sensible option for spot ventilation in a house or workshop.

This is the product at the center of this guide. At USD 8.95, it's an AC-powered muffin fan with a black finish, a 2-pin connection, and a compact 3.1 x 3.1 x 1.5-inch body. The reason to choose it is its small size and price for a confined ventilation task. The limitation is that same compact frame: it's not designed for moving air through large ductwork.
