Graham-White Manufacturing Co.
Graham White
Air Dryers

As the world leader in air drying technology, we can safely boast of an unmatched ability to customize this technology into drying products that match exact and unique applications. Custom applications include size and envelope concerns, withstanding severe shock and vibration along with the ability to survive in dirty, extreme temperature environments. Other challenges include the filtering and drying of severely contaminated hot compressed air, dew point performance tailoring, mounting orientation, and strict AC or DC voltage requirements. The technology leadership of Graham-White is most evident in the heavy rail and rail transit industries worldwide. These markets are where our exceptional track record of fulfilling custom challenges has produced cost effective solutions.

In addition to the high performance filtration packages that are an inherent part of each Graham-White Air Dryer, we also make available an assortment of stand-alone, heavy-duty filters. These unique, high efficiency, stand-alone filters fall into two groups. The first group is a series of Centrifugal / Coalescing filters with automatic drains. The second group is comprised of high efficiency Particulate Filters. It is important to remember that a Centrifugal /Coalescing filter is not an air dryer that reduces the dew point or the relative humidity of the compressed air. Although the Centrifugal filters will remove some of the free water and the Coalescing filters will remove free water and oil aerosols, they do not remove the water vapor that will eventually condensate as the compressed air temperature cools.

Graham-Whites Custom Gauges have long been the standard in Pressure and Flow analog gauge technology for both the heavy rail and rail transit industries. From a pressure stand point, our unique Duplex Pressure Gauge series is an extraordinary single gauge that delivers two separate pressure readings simultaneously. This dual function does the work of two single gauges, requires half the panel space, and costs less. A Series of Air Flow (AF) Indicator Gauges and Air Flow Method (AFM) Indicator Gauges are also available. Both are enhanced with an adjustable base to measure air system leakage across a 19/64" orifice using a pressure differential (psi) or airflow (cfm) scale. All GW gauges are designed with high quality bronze bourdon tubes and precision phosphor bronze movements for optimum performance and reliability. An integral quick disconnect and test feature makes all GW gauges easy to install within your control stand or console and inspect in place using the GW 706-000 Air Gauge and Pressure Switch Tester. An assortment of GW "Quick Disconnect" Test Fittings are available for quick and easy testing of stand alone air gauges and pressure switches.
