Pneumatech AD-425 Non-Cycling 425 cfm Refrigerated Air Dryer, 460v 3 Phase, 2"NPT

The Pneumatech AD series of non-cycling air dryers is one of the most cost effective and reliable solutions to remove condensation and the resultant corrosion from your compressed air system. The AD-425 dryer is a 425 cfm air dryer and is typically paired with a 75hp or 100hp rotary screw air compressor.

Refrigerated air dryers are one of the most common and effective ways to remove moisture and condensation from compressed air systems. Refrigerated dryers (aka fridge dryers) take the warm compressed air that is discharged from the air compressor and cools it rapidly to a 35-39ºF dew point. The cooling process lets the water vapors condense into a liquid which is drained out via the internal automatic drain, causing the air exiting the dryer to be very dry.

Without an air dryer, a significant amount of moisture can accumulate within a compressed air system. Depending on the end use equipment.

Refrigerated air dryers are a fantastic way to remove water from your lines, but often times pre and post dryer filtration are required. A general purpose pre filter will remove dust/debris from entering the dryer, therefore prolonging the life of the dryer. A coalescing oil removal filter can be installed after the air dryer to capture trace oil vapors down to .01ppm and will assist in removing trace water vapors that happen to escape past the dryer.

Do you have questions on compressed air treatment and what would be the most effective solution at removing water and/or containments from your system? Give our office a call and we are happy to assist.
