airspeed 18% faster after air conditioner is cleaned and coated

In a very warm September, Simix cleaned and coated an air conditioner at a large facility in Boone County, Missouri.

The unit was extremely dirty. Before it was coated, the air speed above the fan was 4.2 mph. After the unit was cleaned with Simix Multi-Surface Cleaner, the airspeed was recorded at 8.2 mph.

Immediately after the unit was cleaned, it was coated with Simix A/C Ceramic Coating, and the airspeed was 9.7 mph. That is an 18% improvement over 8.2 mph.
​
That improvement lead to much lower energy costs.
