The TE-6070D-2_5 is a high volume air sampler configured for PM2.5 particulate matter monitoring and research applications. This complete sampling system delivers reliable collection of fine particles 2.5 µm and smaller using a precision size-selective inlet assembly.

Mass Flow Control Technology

The integrated mass flow controller (MFC) maintains consistent volumetric flow rates by automatically adjusting motor speed based on real-time flow feedback. This closed-loop control compensates for filter loading and environmental conditions, ensuring stable sampling performance throughout extended collection periods. The MFC system delivers superior flow regulation compared to constant-speed operation, particularly critical for quantitative PM2.5 mass determination.

Digital Timer and Control System

The digital timer provides precise programming capabilities for automated sampling cycles. Set start times, run duration, and sampling intervals with digital accuracy. The timer system integrates with the MFC controller to deliver coordinated operation and reliable unattended sampling for routine monitoring programs.

Brush Motor Assembly

The proven brush-style motor assembly provides robust, field-tested performance for high volume air sampling applications. This motor configuration offers reliable startup characteristics and consistent operation across varying environmental conditions. Regular brush maintenance ensures continued performance - replacement brushes available separately.

Key Specifications

Power: 110V, 60Hz single-phase
Particle size: PM2.5 (2.5 µm cutpoint)
Flow control: Mass flow controlled (MFC)
Timer: Digital programmable
Motor: Brush-style high volume
Housing: Anodized aluminum weather shelter

Compatibility and Configuration

This sampler accepts standard 8×10 inch or 20.3×25.4 cm filter media. The PM2.5 size-selective inlet requires regular inspection and cleaning to maintain proper cutpoint characteristics. Compatible with quartz microfiber, glass fiber, and PTFE membrane filters depending on analysis requirements.

Applications

Designed for ambient air quality monitoring, source assessment studies, and institutional research programs. Current EPA primary annual PM2.5 standards are set at 9.0 micrograms per cubic meter, making accurate PM2.5 measurement increasingly important for compliance and health protection studies. This sampler configuration supports non-regulatory monitoring programs requiring reliable, high-volume particulate collection with automated operation capabilities.
