It’s important to remember a few basics about combining fixed speed and Variable Frequency Drive (VFD) screw air compressors before discussing control gap, which I wrote about in a previous article. The article is available at (. .
Now that you know the proper way to set a VFD air compressor’s control pressure in a system, let’s discuss the problem as it relates to screw air. .
Let’s finally get to the solution! Here are some recommendations. 1. Right-sized VFD air compressor: The first and best solution is to use a. .
For this project, I could have recommended either a larger VFD air compressor or a small base-load air compressor, and a target sequencer, but the air compressors. .
A case study illustrates the problem. In this case, an actual 75 HP air compressor system was improved by the addition of a 75 HP VFD air.

Mount a thermometer in the compressor room. Increase ventilation if room temperature exceeds operating limits. Inspect and remove/vacuum loose dust from inlet filters. Frequency depends on ambient dust load. Inspect and vacuum ambient side of coolers. Frequency depends on ambient dust load.
