TE-5170DBL TSP Hi-Vol Air Sampler - MFC, Digital Timer, Brushless, 110V SKU: TE-5170DBL

TE-5170DBL TSP Hi-Vol Air Sampler - MFC, Digital Timer, Brushless, 110V

The TE-5170DBL is a high volume air sampler engineered for Total Suspended Particulate (TSP) collection in compliance with 40 CFR Part 50, Appendix B. This system delivers reliable ambient air monitoring with no size-selective inlet, capturing particles with aerodynamic diameters of approximately 100 µm or less. Designed for environmental agencies, industrial hygienists, and research institutions conducting regulatory monitoring and ambient air quality assessment.

Mass Flow Control Technology

The MFC (Mass Flow Controller) maintains stable flow rates by continuously monitoring and adjusting motor speed based on real-time flow feedback from a hot wire anemometer probe. The hot wire anemometer probe is inserted into the flow stream and automatically adjusts the motor speed as the filter begins to collect particulate. This ensures consistent sampling conditions throughout the collection period, compensating for filter loading and environmental variations. The flow rate is user adjustable between 39 and 60 cfm, meeting EPA specifications for TSP reference method sampling.

Key Specifications

• Flow Rate Range: 39 to 60 CFM (user adjustable with MFC)
• Motor Type: Brushless (maintenance-free operation)
• Power: 110V, 60Hz
• Timer: Digital programmable timer with battery backup
• Filter Size: 8" × 10" glass fiber filters
• Shelter: Anodized aluminum outdoor enclosure

Digital Timer and Data Management

The integrated digital timer provides precise sampling period control with programmable start/stop functions and internal battery backup to maintain schedules during power interruptions. These systems are available with either a 7 day mechanical timer or a US EPA recommended digital timer to ensure accurate sampling results. The digital timer eliminates the need for manual timing adjustments and provides consistent 24-hour sampling periods required by EPA regulations.

Brushless Motor Advantages

Brushless motors do not use motor brushes or require maintenance, significantly reducing operational costs and downtime. Unlike brush-style motors that require periodic carbon brush replacement, the brushless design provides extended service life and consistent performance in continuous field operation. This motor configuration is particularly suited for remote monitoring locations where routine maintenance access is limited.

System Components and Construction

The TE-5170DBL includes an anodized aluminum shelter designed for long-term outdoor deployment, stainless steel filter holder with integrated pressure monitoring, continuous flow/pressure recorder, and elapsed time indicator. The shelter is designed to allow particulate matter to be drawn on to the filter from all four sides. The rugged construction of the outdoor enclosure allows it to withstand the elements with minimal maintenance. The system provides comprehensive documentation of sampling conditions through integrated monitoring instruments.

Regulatory Compliance and Applications

This sampler meets all requirements specified in 40 CFR Part 50, Appendix B for TSP reference method sampling. This method provides a measurement of the mass concentration of total suspended particulate matter (TSP) in ambient air for determining compliance with the primary and secondary national ambient air quality standards for particulate matter. The measurement process is nondestructive, and the size of the sample collected is usually adequate for subsequent chemical analysis. Applications include NAAQS compliance monitoring, industrial perimeter monitoring, research studies, and environmental impact assessment.

Compatibility and Calibration

The TE-5170DBL requires the TE-5028 calibration kit for field calibration and flow verification. The system accepts standard 8" × 10" glass fiber filters meeting EPA specifications. For laboratories conducting lead analysis, collected samples can be analyzed using EPA-approved methods including ICP-MS procedures as specified in current federal regulations. Regular calibration ensures data quality and regulatory compliance for ambient air monitoring networks.
