What it does

Tapered shape made to couple a 120mm fan to PVC pipe ducting
Lets you build a forced air chamber so airflow reaches your setup
Tapered profile guides air from the fan into the pipe opening
Made to order in the USA after you place your order
A workshop tool for anyone building a small ducted air system

Workshop projects that move air need a clean path from fan to pipe. This fan cowl gives you that path. It couples a 120mm fan to PVC pipe so you can build a forced air chamber for your ducting setup.

The cowl is tapered, narrowing from the fan side down to the pipe side. This shape is built to guide airflow from the fan opening into the pipe run. You can join it with matching pipe pieces to extend your ducting as far as your project needs.

It works well for small workshop builds, cooling setups, or any project where you need to route air through PVC pipe. The cowl is made to order in the USA after you place your order.
