SEMTECH-FS: Gravimetric Filter System
The SEMTECH Filter System includes a cyclonic separator, which removes coarse particles upstream of the 47mm filters. The system can be completely operated with the easy-to-use interface panel, allowing for the selection of one of three fiters, or a bypass line. The front panel door allows for easy access to change the filter elements. Power is provided for a heated sample line. The system meets US EPA 1065 measurement criteria and can be used either on-board or in a test cell.

1065 Compliant:The SEMTECH Filter System is designed to meet the sampling requirements and recommendations of CFR40 part 1065 for both in-use and test cell applications.
Cyclonic Separator: The exhaust sample first passes through a heated cyclonic separator to remove coarse elements prior to passing through the filter elements.
Three Filter Paths: The system contains three, 47mm diameter filter holders. The system can be set to automatically switch between these filters and the bypass line, in accordance with pre-set test conditions. Pneumatic ball valves and downstream isolation solenoids are used to select the desired flow path.
Low Maintenance: The unit was designed with an easy access door to remove the filter holders and replace the filter elements. Other access panels enable easy removal of the cyclone and fuse panel.
Easy Operation:The built-in display panel shows all of the information needed to manually operate the unit. Temperature settings, flow settings and status indicators are all clearly defined and user configurable.
