The TE-5170VXZ is a complete high-volume air sampler configured for Total Suspended Particulate (TSP) sampling in compliance with EPA primary and secondary national ambient air quality standards. This system draws ambient air through a filter to collect particles with aerodynamic diameters of approximately 100 µm or less, providing comprehensive particulate matter collection for regulatory monitoring and research applications.

Volumetric Flow Control Operation

The Volumetric Flow Control (VFC) system uses a calibrated critical orifice to maintain consistent volumetric flow rates throughout the sampling period. The critical orifice is drilled and calibrated to allow only the predetermined flow rate to pass through the filter, while the motor operates wide open as the critical orifice maintains constant flow. This approach provides reliable flow control with minimal electronic complexity, making it well-suited for continuous field deployment.

Key Specifications

Power: 220V, 60Hz configuration
Motor Type: Brush-style motor for proven field reliability
Timer: Mechanical 7-day timer for simple operation
Flow Rate: 40-60 ft³/min (1.1-1.7 m³/min) per EPA requirements
Sampling Period: 24-hour nominal (1,440 ±60 minutes)
Housing: Anodized aluminum outdoor shelter with gabled roof

Regulatory Compliance

This sampler meets the requirements of 40 CFR Part 50, Appendix B for TSP reference method sampling. The system is designed for 24-hour sampling periods where a measured quantity of ambient air is drawn through a filter, enabling gravimetric determination of total suspended particulate matter concentration expressed in micrograms per standard cubic meter.

System Configuration

The TE-5170VXZ includes all core components needed for routine TSP monitoring: VFC flow controller, mechanical timer, brush motor assembly, anodized aluminum shelter, and integrated mounting hardware. The shelter design allows particulate matter to be drawn onto the filter from all four sides, ensuring representative sampling per EPA method requirements.

Applications

Ideal for environmental monitoring agencies, industrial facilities, and research institutions conducting ambient air quality assessment. The TSP method remains the required sampling approach for lead monitoring in accordance with 40 CFR Part 50, Appendix B, and supports various research applications requiring comprehensive particulate matter collection. The 220V 60Hz configuration suits international deployment and locations with higher voltage power systems.

Maintenance Considerations

The brush-style motor provides field-proven performance with established maintenance intervals. Regular inspection of motor brushes and replacement per manufacturer guidelines ensures consistent sampling performance. The mechanical timer offers dependable operation with minimal electronic components requiring maintenance in harsh field environments.
