TE-5170V Hi-Vol TSP Sampler, VFC, Mechanical Timer, Brush Motor, 110V SKU: TE-5170V

The TE-5170V is a high-volume Total Suspended Particulate (TSP) air sampler designed for ambient air quality monitoring in compliance with EPA reference method 40 CFR Part 50, Appendix B. This sampler draws a measured quantity of ambient air through a filter during a 24-hour sampling period to determine TSP mass concentration. The TE-5170V features a Volumetric Flow Controller (VFC), 7-day mechanical timer, brush-style motor, and operates on 110V/60Hz power.

Volumetric Flow Control Technology

The VFC system uses a critical orifice with a predetermined diameter to maintain constant flow rate throughout the sampling period. The sampler maintains flow rates between 40-60 ft³/min (1.1-1.7 m³/min) to collect particles with aerodynamic diameters up to approximately 100 µm, corrected to EPA standard conditions of 25°C and 760 mm Hg. The motor operates at full capacity while the critical orifice regulates the actual sampling flow rate.

Key Specifications

• Flow Control: Volumetric Flow Controller (VFC) with critical orifice
• Motor: Brush-style, 110V, 60Hz
• Timer: 7-day mechanical timer for automated sampling schedules
• Sample Period: 24-hour nominal sampling periods
• Dimensions: 15" × 15" × 52" assembled
• Construction: Anodized aluminum outdoor shelter with gabled roof

System Components

The TE-5170V includes an anodized aluminum outdoor shelter designed to draw particulate matter from all four sides, a filter holder assembly, brush-style vacuum motor, VFC flow control system, pressure chart recorder for flow documentation, and an elapsed time indicator for motor maintenance tracking. The rugged outdoor enclosure withstands environmental conditions with minimal maintenance requirements.

Regulatory Compliance

This sampler meets EPA reference method requirements specified in 40 CFR Part 50, Appendix B for TSP measurement. TSP samplers continue to be required for lead monitoring in ambient air under current NAAQS standards. The collected samples provide data for determining compliance with ambient air quality standards and enable subsequent chemical analysis of collected particulates.

Applications

• EPA-compliant ambient air quality monitoring
• Lead monitoring under NAAQS requirements
• Environmental compliance monitoring for industrial facilities
• Research applications requiring TSP data
• Long-term air quality trend monitoring

Maintenance Notes

The brush-style motor requires periodic brush replacement based on operating hours recorded by the elapsed time indicator. The 7-day mechanical timer provides reliable sampling schedules with minimal maintenance. Regular calibration ensures accurate flow measurements throughout the sampler's operational life. This unit includes a 1-year manufacturer warranty and is made in the USA.
