SEMTECH-PFS: Particulate Filter System
The innovative filter holder uses the industry standard 47 mm filter cartridge along with custom inlet and outlet cones to achieve required filter face velocities for a wide range of flow rates. The system is controlled by a microprocessor, which directs the sample through one of three filters, or through a bypass using solenoid valves.

- Options
- 1065 Compliant: The SEMTECH-PFS meets the US EPA 1065 compliance requirements for in-use testing.
- Direct Sample Path: Diluted sample is routed directly from the MPS to the PFS through a gas interconnect, which joins the bottom outlet of the MPS module to the top inlet of the PFS module.
- Quick Release Filter Holder Assembly: Easily change both filters and filter holders with this quick-release design to access all three filters at once.
- Graphical Panel Display: A full color, graphic touch screen displays live data, and enables system setup and basic functions.
- Power Supply Monitoring: Power can be either 12 VDC, 110 VAC or 220 VAC, with both current and voltage monitoring.
- Weatherproof Construction: All components meet IP54 (NEMA 3) standards.
- Shock Resistance: The mechanical design has been optimized for resistance to shock and vibration, ensuring data in the most rugged of in-use environments.
- Design Details: Over a decade of experience in in-use emissions testing has gone into the design details of the SEMTECH ECOSTAR system, including:
- EMI protection, including gaskets, filters and capped connectors
- Stress relief for pneumatic connections
- Channels for cable management
- Standard Swagelok™ bulkhead connectors
- Rugged Deutsch connectors for power and auxiliary connectors
- Handles that lock to other SEMTECH ECOSTAR modules for stable system integration
