SF100 Filtration Unit

1.0 INTRODUCTION

1.1 System Description

The SF100 Self Cleaning Filter Unit is designed to protect the

CA-6 Colorimetric Analyzer from fouling due to particles in the

sample stream. Air pressure is used to clean the filter element.

Timers periodically actuate a solenoid that sends pressurized air

back through the filter element, blowing any material off of the

filter and back into the sample line. Both the period and the

duration of the Blow Back Cycle are user selectable.

The Filter Unit should be plumbed into an area of high velocity

to maximize the time between cleaning cycles. Higher velocities

seem to minimize sedimentation on and fouling of the filter

element.
