The TE-5170BLX high-volume air sampler delivers EPA-compliant total suspended particulate (TSP) sampling per 40 CFR Part 50, Appendix B, the federal reference method for ambient air quality monitoring. Configured for 39-60 ft³/min flow rates over 24-hour sampling periods, this sampler captures particles up to 25-50 µm aerodynamic diameter without size-selective separation.

Mass Flow Control Technology

The integrated MFC (Mass Flow Controller) system uses a hot wire anemometer probe positioned in the airstream to maintain constant volumetric flow throughout the sampling period. This flow controlling mechanism maintains constant air flow during the sampling period, automatically adjusting motor speed as filter loading increases resistance. The controller compensates for ambient temperature and barometric pressure variations to deliver consistent mass flow rates essential for accurate concentration calculations.

Brushless Motor Design

The brushless motor assembly eliminates routine brush replacement maintenance while providing reliable operation in continuous field deployment. This motor configuration reduces service intervals and extends operational life compared to traditional brush-style motors, particularly valuable for remote monitoring locations where maintenance access is limited.

Key Specifications

Power Requirements: 220V, 50Hz configuration
Flow Rate: 39-60 ft³/min (1.1-1.7 m³/min)
Filter Size: 8″ × 10″ glass fiber filters
Timer: 7-day mechanical timer with dependable start/stop control
Sampling Period: 24-hour nominal (1,440 ±60 minutes)

Complete Shelter Package

Housed in an anodized aluminum shelter with gabled roof design, the sampler draws ambient air from all four sides for representative particulate collection. The weather-resistant enclosure protects internal components while maintaining the open-face inlet geometry required by the EPA reference method. Includes chart recorder for pressure monitoring and elapsed time indicator for maintenance tracking.

EPA Compliance Applications

Essential for ambient air monitoring networks supporting National Ambient Air Quality Standards (NAAQS) compliance, particularly for lead monitoring where measurement of airborne Pb continues to be performed by Hi-Vol TSP samplers in accordance with 40 CFR Part 50, Appendix B. Suitable for State and Local Air Monitoring Station (SLAMS) networks, industrial source monitoring, and research applications requiring gravimetric particulate analysis.

Configuration Note

The TE-5170BLX represents the MFC, brushless motor, 220V 50Hz version within Tisch Environmental's TE-5170 sampler series. Alternative configurations include VFC (Volumetric Flow Control), brush-style motors, and different voltage/frequency combinations to match specific site requirements and regional power standards.
