The TE-5170DVBLX is a high volume air sampler engineered for Total Suspended Particulate (TSP) collection following 40 CFR Part 50, Appendix B reference method requirements. This configuration delivers reliable ambient air monitoring with reduced maintenance demands through brushless motor technology and precise volumetric flow control.

Volumetric Flow Control (VFC) Operation

The VFC system uses a critical orifice with predetermined diameter to control flow rate. The critical orifice is drilled and calibrated to maintain the specified flow rate throughout the sampling period, automatically compensating for filter loading without requiring operator intervention. TSP sampling operates at flow rates between 40-60 ft³/min over constant sampling periods, ensuring EPA compliance for ambient particulate monitoring.

Key Specifications

Power: 220V, 50Hz configuration for international applications
Motor: Brushless design reduces maintenance requirements and extends service life
Timer: Digital programming for precise, repeatable sampling schedules
Flow Control: VFC maintains consistent volumetric flow regardless of filter loading
Housing: Anodized aluminum shelter with weather-resistant construction

Brushless Motor Advantages

The brushless motor eliminates the need for routine brush replacement, a significant maintenance requirement in continuous field monitoring applications. This motor technology provides consistent performance over extended deployment periods while reducing operational costs and site visits for routine maintenance.

Digital Timer Control

The digital timer offers programmable sampling schedules with greater precision than mechanical timers. Digital control ensures accurate start/stop timing for regulatory compliance sampling, with clear display of elapsed time and remaining sample period.

Applications

TSP monitoring supports ambient air quality assessment for particles with no size-selective inlet, collecting the full range of suspended particulate matter. This sampler configuration serves ambient air quality networks, industrial boundary monitoring, and research applications requiring 24-hour integrated TSP samples on glass fiber filters for gravimetric analysis and subsequent chemical characterization.

The TE-5170DVBLX provides field-proven reliability for continuous ambient monitoring programs where consistent performance and minimal maintenance are essential operational requirements.
