Moisture Separators & Drain Valves

The amount of condensate generated within a compressed air system can be surprising. As an example, a 500 scfm system operating in ambient conditions of 60°F and 65% relative humidity can generate nearly 2 gallons of liquid condensate per hour. That condensate, however, will be generated at a number of points within the system. All of this condensate must be removed from the compressed air system. This is accomplished with the use of drain valves.

When oil is present, as with oil lubricated compressors, the condensate must be purified to legal levels of residual oil content before it can be discharged to public water treatment systems. Typically, condensate will contain on the order of 5% oil. That level must be reduced to 20 ppm or lower, depending on local ordinances.

DS oil/water separators utilizes gravity to separate oil/water mixtures and purify the condensate to a residual oil content of 20 ppm or lower. Designed to effectively and efficiently separate oil from compressed air condensate this unit is available in 7 models ranging from 70 to 4,500 cfm. The DS Series are easy to install, operate and maintain. They require no power, unless fitted with an optional heater, and operate without intervention between maintenance intervals.
