(Envent Field Station)

Self-Contained Pre-Sampling System

The EFS is a multi-function miniaturized pre-sample conditioning system probe-mounted and installed at the sample point. The EFS allows for the filtration and pressure reduction of process samples allowing for faster response times and a representative sample to the analyzer. With over 300 preassembled, field-serviceable configurations, the EFS is designed to meet a multitude of sample conditions. Envent engineers can design a custom solution specific to your unique applications.
