The TE-5170DVBL is a high-volume air sampler designed for total suspended particulate (TSP) collection in compliance with EPA reference method requirements. This complete sampling system delivers reliable TSP monitoring for ambient air quality assessment, environmental compliance, and research applications.

Volumetric Flow Control Technology

The sampler employs a Volumetric Flow Controller (VFC) that maintains consistent flow rates through differential pressure measurement. The VFC uses a calibrated critical orifice to control flow rate while the motor operates at full capacity, ensuring stable volumetric flow regardless of filter loading. This design provides excellent long-term flow stability throughout the required 24-hour sampling period (1,440 ±60 minutes).

Key Specifications

Flow Rate: 42-45 CFM continuous operation
Power Requirements: 110V, 60Hz single phase with earth ground
Motor: Brushless blower motor for reduced maintenance
Timer: Digital timer with programmable sampling periods
Operating Range: -30°C to +50°C ambient temperature, up to 10,000 feet elevation
Current Draw: 20 amps startup, 8 amps running

Regulatory Compliance

This sampler meets EPA TSP reference method requirements as specified in 40 CFR Part 50, Appendix B. The high-volume design collects particles with aerodynamic diameters of approximately 100 µm or less, providing comprehensive particulate matter assessment for TSP monitoring applications.

System Components and Compatibility

The complete system includes an anodized aluminum outdoor shelter (48" x 20" x 20"), brushless blower motor assembly, VFC unit, digital timer, 24-hour chart recorder, 30" water manometer, and filter holder assembly. Uses standard 8" x 10" glass fiber filters for sample collection. The brushless motor design eliminates routine brush replacement, reducing field maintenance requirements compared to traditional brush-style motors.

Digital Timer and Data Recording

The integrated digital timer provides precise sampling period control with programmable start/stop functions and sample delay capabilities up to 7 days. The system includes continuous flow/pressure recording via chart recorder for flow verification and regulatory documentation requirements.

Applications

Ideal for ambient air quality monitoring networks, environmental compliance monitoring, industrial source assessment, and research applications requiring TSP data collection. Suitable for permanent installation in monitoring networks or portable deployment for short-term studies.
