The TE-5170VBLX is a high volume air sampler specifically configured for Total Suspended Particulate (TSP) sampling in compliance with EPA reference method requirements. This system collects ambient particulate matter with no size-selective inlet, capturing particles with aerodynamic diameters of approximately 100 µm or less as specified in 40 CFR Part 50, Appendix B.

Volumetric Flow Control Technology

The VFC (Volumetric Flow Controlled) system uses a critical orifice with a predetermined orifice hole diameter to control the flow rate, with the critical orifice drilled and calibrated to let only the predetermined flow rate pass through the filter. This design maintains consistent volumetric flow rates across varying field conditions by measuring differential pressure, ensuring accurate sample collection over the entire sampling period.

Key System Components

Brushless Motor: Reduces routine maintenance requirements and extends service life in continuous field applications
Mechanical Timer: Provides simple, dependable start and stop control with proven reliability
220V 50Hz Power: Configured for international electrical standards
Anodized Aluminum Shelter: Weather-resistant housing designed for long-term outdoor deployment

Flow Rate & Performance

The system operates at flow rates between 39-60 cubic feet per minute (ft³/min), maintaining consistent volumetric sampling throughout the required 1,440 ±60 minute (24-hour) sampling period. The VFC technology ensures accurate volume measurement without the complexity of electronic flow controllers.

Compatibility & Configuration Options

The TE-5170VBLX is part of Tisch Environmental's comprehensive TE-5170 series, which includes multiple timer, motor, power, and controller configurations. Alternative models in the same series include brush motor versions (TE-5170V, TE-5170VX, TE-5170VXZ), 110V versions (TE-5170VBL), and MFC-controlled options for different operational requirements.

Applications

This sampler serves ambient air quality monitoring programs, environmental compliance assessments, and research applications requiring EPA Federal Reference Method (FRM) compliant TSP collection. The collected samples support gravimetric analysis for particulate concentration determination and subsequent chemical analysis for metals content, including lead monitoring applications.

The TE-5170VBLX delivers reliable, maintenance-efficient TSP sampling with straightforward operation, making it suitable for long-term monitoring stations, compliance networks, and field research deployments requiring consistent performance in varied environmental conditions.
