Edwards Vacuum Rotary Piston
Oil sealed rotary piston pumps cover a broad pressure range and provide very high volumetric efficiency throughout most of the pressure range. Power requirements are modest and water consumption is low since it is a valved compressor. The installation of oil sealed rotary piston pumps is simple and inexpensive.
For over a century, the Stokes Microvac has set the industry standard for robust, reliable vacuum performance. The J-Series continues this legacy, combining a time-tested mechanical design with modern refinements to deliver maximum uptime in the most demanding environments.
