Why does my Trane economizer unit need a metal air filter screen?

Trane rooftop economizers require an aluminum pre-filter screen to protect the equipment from outdoor elements. Without a metal air filter, large airborne particulate will enter the unit and potentially damage the high-efficiency filters inside. This negatively affects unit performance and increases repair and maintenance costs. Installing a quality metal air filter provides protection, improves performance and reduces service costs.

What is the best metal air filter to use for the Trane economizer?

The best metal air filters are durable, washable and reusable. Our filters use a high-quality media pack with face grids on both sides, which keep the media tight inside the frame for a rigid and durable filter. It allows the filter to operate at high airflow speeds and withstand repeated washings.
