The TE-6070X-2_5 is a high volume air sampler specifically configured for collecting fine particulate matter at 2.5 µm or smaller for non-regulatory ambient air monitoring and institutional research applications. This complete sampling system integrates a PM2.5 size-selective inlet with proven mass flow control technology to maintain consistent sampling conditions throughout extended field deployments.

Flow Control Technology

The integrated mass flow controller (MFC) automatically maintains the set flow rate by continuously adjusting motor speed based on real-time flow feedback. This closed-loop control system compensates for filter loading, ambient temperature variations, and barometric pressure changes that would otherwise affect sampling accuracy. The MFC ensures stable volumetric flow rates critical for quantitative PM2.5 mass concentration measurements.

Operational Specifications

Power Configuration: 220V, 50Hz for international field applications
Motor Type: Brushed motor assembly delivers field-proven reliability in high-volume sampling applications
Timer Control: Mechanical timer provides simple, dependable start/stop scheduling without electronic complexity
Sample Collection: PM2.5 size-selective inlet captures particles ≤2.5 µm aerodynamic diameter

System Configuration and Housing

The sampler is housed in an anodized aluminum shelter that protects all core components from environmental conditions while maintaining proper ventilation and access for routine maintenance. The shelter includes mounting provisions for the sampling head, motor housing, control electronics, and flow measurement instrumentation. All components are configured for reliable operation in ambient temperature ranges from -30°C to +45°C.

Applications

This configuration serves research institutions, environmental consultants, and industrial hygiene professionals conducting ambient PM2.5 characterization studies. The sampler supports non-regulatory monitoring programs focused on fine particulate matter exposure assessment, source apportionment studies, and enclosed environment monitoring. While not designed for 40 CFR Part 50, Appendix L compliance, the system provides quantitative PM2.5 mass measurements suitable for comparative studies and trend analysis.

Maintenance and Operation

The mechanical timer eliminates the need for complex programming while providing reliable unattended operation. Brushed motor design allows for straightforward field maintenance with readily available replacement components. Regular maintenance includes filter changes, flow rate verification, and periodic brush inspection according to Tisch Environmental's recommended service intervals.
