72R3110 diffuser provides controlled, adjustable airflow for heavy-duty truck cabs, HVAC systems, and equipment enclosures. Featuring a 3.5″ diffuser outlet and an angled base, this design helps direct airflow where it’s needed most, improving comfort and air distribution.
The diffuser installs into a 3-5/16″ mounting hole and includes an integrated spring for secure retention during installation. Its angled base makes it well suited for dash, panel, or enclosure locations where straight-through mounting is not ideal.
Manufactured to OEM-grade standards and sourced from trusted industry suppliers, this diffuser offers long service life and dependable performance in demanding commercial environments.
