The TE-5170VFCBL 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 sampler collects particles with aerodynamic diameters of approximately 100 µm or less at flow rates between 40-60 ft³/min during 24-hour sampling periods for ambient air monitoring and research applications.

PLUS Technology Flow Control

The VFC PLUS controller uses a microprocessor-based system with built-in ambient temperature and barometric pressure sensors for accurate, real-time flow control. The total volume of air sampled is corrected to EPA standard conditions (25°C, 760 mm Hg [101 kPa]), ensuring precise volumetric measurements throughout the sampling period. The PLUS controller automatically maintains constant flow rates using a critical orifice system, eliminating the need for manual adjustments as filter loading increases.

Key Specifications

Controller: VFC PLUS with microprocessor-based flow control
Motor: Brushless design for extended service life and reduced maintenance
Power: 110V, 60Hz electrical configuration
Timer: Digital timer with battery backup for uninterrupted operation
Flow Rate: 40-60 ft³/min (EPA compliant range)
Sample Type: Total Suspended Particulate (TSP)

Data Logging and Control Features

The PLUS controller includes comprehensive data logging capabilities with four separate data logs capturing average, minimum, and maximum ambient temperature and barometric pressure, along with total ambient and standard flow measurements. Data retrieval is simplified through USB export functionality. The built-in digital timer features battery backup, multiple elapsed time indicators, and programmable sampling schedules including 1-in-3, 1-in-6, 1-in-7, and custom intervals.

Applications

This sampler configuration is designed for:

EPA-compliant ambient air quality monitoring programs
Environmental research requiring TSP measurements
Industrial source assessment and compliance monitoring
Academic studies of atmospheric particulate matter
Baseline air quality characterization studies

Construction and Housing

The complete system includes an anodized aluminum outdoor shelter with gabled roof assembly, designed to allow particulate matter collection from all four sides. The rugged construction withstands environmental conditions with minimal maintenance requirements. The brushless motor design significantly reduces routine maintenance compared to brush-style motors, supporting reliable long-term field deployment.

Note: TSP sampling requires a 24-hour sampling period (1,440 ±60 minutes) for valid sample collection according to EPA reference method specifications. This sampler provides the reliable, high-volume collection capability needed for accurate TSP determination with an easy-to-operate PLUS technology control package.
