TE-5170VZ TSP Hi-Vol Sampler - VFC, Mechanical Timer, Brush Motor, 110V 50Hz SKU: TE-5170VZ

The TE-5170VZ is a high volume air sampler configured for Total Suspended Particulate (TSP) sampling in accordance with EPA reference method requirements. This system provides measurement of the mass concentration of total suspended particulate matter in ambient air for determining compliance with national ambient air quality standards.

Volumetric Flow Control System

The VFC configuration uses a critical orifice with a predetermined orifice hole diameter to control the flow rate, drilled and calibrated to maintain the predetermined flow rate through the filter. The motor operates wide open while the critical orifice maintains constant flow rate. Flow rates are maintained between 40-60 ft³/min (1.1-1.7 m³/min) over the sampling period.

Control and Timing Components

The mechanical timer provides simple, dependable start and stop control for routine field operations. The elapsed time indicator is a mechanical clock that counts hours and minutes during active sampling, used to track motor life, brush changes, and verify sampling time. This configuration includes a brushed motor assembly - a proven, field-ready drive system widely used in hi-vol sampling applications.

Key Specifications

• Power: 110V, 50Hz configuration
• Flow control: Volumetric Flow Controlled (VFC) with critical orifice
• Motor type: Brush-style motor assembly
• Timer: Mechanical 7-day timer system
• Sample period: 24-hour nominal (1,440 ±60 minutes for valid samples)

Shelter and Construction

Housed in an anodized aluminum shelter with gabled roof assembly, designed to allow particulate matter to be drawn onto the filter from all four sides, with rugged construction to withstand elements with minimal maintenance.

Regulatory Compliance

TSP sampling complies with EPA reference method requirements codified at 40 CFR Part 50, Appendix B. The sampler geometry and flow rate favor collection of particles up to 25-50 µm (aerodynamic diameter), depending on wind speed and direction.

Applications

Designed for ambient air quality monitoring programs requiring EPA-compliant TSP measurements. The measurement process is nondestructive, and collected samples are typically adequate for subsequent chemical analysis. Suitable for environmental monitoring agencies, research institutions, and industrial compliance monitoring programs.
