PM2.5 High Volume Air Sampler with VFC Control

The TE-6070VX-2_5 delivers precise PM2.5 particulate sampling for environmental monitoring and research applications. This complete high volume air sampler integrates a size-selective PM2.5 inlet with volumetric flow control (VFC) technology to maintain consistent sampling flow rates across varying field conditions.

Volumetric Flow Control Technology

The VFC system uses differential pressure measurement to automatically adjust blower speed and maintain the target volumetric flow rate. Unlike mass flow controllers that measure mass flow, VFC ensures consistent volumetric sampling regardless of temperature, pressure, and filter loading variations encountered during field deployment.

Key Specifications

Sample Type: PM2.5 (particles 2.5 µm and smaller)
Flow Control: Volumetric Flow Control (VFC)
Timer: Mechanical timer for dependable start/stop control
Motor: Brushed motor assembly - proven field-ready drive system
Power: 220V, 50Hz configuration
Housing: Anodized aluminum shelter with weather protection

PM2.5 Monitoring Applications

This sampler supports PM2.5 monitoring requirements found in 40 CFR part 58 Appendix D for non-regulatory studies and institutional research. The PM2.5 size-selective inlet captures fine particulate matter associated with combustion sources, secondary aerosol formation, and long-range transport - critical for understanding air quality impacts on public health.

EPA has set the primary annual PM2.5 standard at 9.0 micrograms per cubic meter, making accurate PM2.5 sampling essential for environmental monitoring programs assessing compliance trends and public health protection.

Mechanical Timer and Brush Motor Reliability

The mechanical timer provides simple, dependable sampling schedule control without the complexity of electronic programming. The brushed motor assembly offers proven performance in high volume sampling applications, with straightforward maintenance requirements and widely available replacement parts.

International Power Configuration

The 220V, 50Hz power configuration suits international deployments and regions with 50Hz electrical systems. This sampler delivers the same sampling performance as 110V models while accommodating different power infrastructure requirements.

Complete Field-Ready Package

Housed in a durable anodized aluminum shelter, this sampler includes all core components needed for routine PM2.5 sampling operations. The integrated design minimizes field assembly requirements and provides weather protection for reliable long-term deployment.
