These controllers were installed and, to the best of my knowledge, never put into service. They are listed as used because there is no box. I have the FA110IH housings and filters from the same installation and they are clean.
I use them in my shop and love it. The Ingersoll Rand 1 L to R Pace Flow Controller, model number 49124373, is a stationary air compressor designed to provide precise control over the flow of air.
This model is ideal for industrial applications and is part of the Ingersoll Rand brand, known for quality pneumatic equipment. The power supply for this flow controller is air, making it a reliable and efficient option for businesses and industries requiring consistent air flow control.
