Particulate Filter System

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.

  • Features
  • Specifications
  • 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 240 VAC, with both current and voltage monitoring.
  • Rugged Construction: The unit can be used off-road and in other harsh environments.
  • 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
