Sullivan Air ‘PPI Boxes’ are constructed from premium phenolic aluminum panels, featuring a black internal surface for a more aesthetically pleasing result when paired with a Sullivan Air diffuser.

Unlike traditional sheet metal boxes, Sullivan Air ‘PPI Boxes’ offer several key advantages:

1. Minimal air leakage

2. Built-in insulation with a clean internal black surface

3. Fewer supports required

4. Significant cost savings

5. Custom sizes available to meet project needs

Competitor products made from traditional sheet metal often lack insulation and are prone to higher air leakage, requiring additional supports and resulting in increased costs. Sullivan Air’s design solves these issues, providing a more efficient and visually appealing solution.
