The TE-5170VFCX is a high volume air sampler configured for Total Suspended Particulate (TSP) sampling in compliance with 40 CFR Part 50, Appendix B. This EPA reference method captures particles with aerodynamic diameters of approximately 100 µm or less at flow rates between 39-60 ft³/min, making it suitable for ambient air monitoring, research applications, and regulatory compliance monitoring.

PLUS Technology Flow Control

The VFC PLUS controller represents advanced ambient air sampling technology. It utilizes a microprocessor based controller for instantaneous and accurate flow control. The system's built in temperature and barometric pressure sensors along with the microprocessor-based mass flow controller allow the system to accurately calculate the flow rate. The total volume of air sampled, corrected to EPA standard conditions (25°C, 760 mm Hg [101 kPa]), is determined from the measured flow rate and the sampling time.

Key Specifications

Power: 220V, 50Hz configuration
Motor Type: Brush-style motor for proven field reliability
Controller: VFC PLUS with microprocessor-based flow control
Timer: Digital timer with battery backup
Flow Rate: 39-60 ft³/min constant flow
Sample Period: 1,440 ±60 min. for a valid sample

Data Logging and Control Features

The PLUS technology flow controllers include a built in digital timer with internal battery backup, multiple elapsed time indicators, and four data logs with an external USB drive for data retrieval. Data logs capture average, minimum, and maximum ambient temperature and barometric pressure, along with total ambient and standard flow measurements. Auto calibration functionality ensures consistent performance throughout sampling periods.

Compatibility and Applications

Designed for TSP monitoring applications including ambient air quality assessment, source emission monitoring, and environmental compliance. The system operates with standard 8×10 inch glass fiber filters meeting EPA specifications. The concentration of total suspended particulate matter in the ambient air is computed as the mass of collected particles divided by the volume of air sampled, corrected to standard conditions, and is expressed in micrograms per standard cubic meter (µg/std m³).

Regulatory Compliance

Fully compliant with EPA TSP reference method requirements. The collected samples can be analyzed for particulate mass concentration and are suitable for subsequent chemical analysis of metals and other constituents. This configuration supports regulatory monitoring programs requiring accurate, traceable particulate matter measurements under varying environmental conditions.
