The TE-6070DBLXZ-2.5 is a high volume air sampler configured for PM2.5 particulate matter collection per 40 CFR Part 50, Appendix L reference method standards. This method provides for the measurement of the mass concentration of fine particulate matter having an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM2.5) in ambient air over a 24-hour period for non-regulatory monitoring and institutional research applications.

Mass Flow Control Technology

The mass flow controller adjusts the motor speed as the filter media collects particulate to maintain a constant flow rate throughout the entire sample duration using a hot wire anemometer probe inserted into the flow stream. This active flow control compensates for filter loading effects and environmental conditions to deliver consistent sampling performance across the entire 24-hour sampling period.

Key Specifications

Flow Rate: 40 cfm (adjustable) (1.02 to 1.24m³)
Filter Media: 8" x 10" standard filter paper in stainless steel filter holder
Motor: Maintenance free brushless motor
Power: 220V, 60Hz configuration
Timer: US EPA recommended digital timer with auto calibration function
Enclosure: Anodized aluminum shelter with robust electrical components for continuous 24 hour operation

Brushless Motor Advantages

The brushless motor design eliminates routine brush replacement maintenance while supporting extended field operation. Unlike brush-style motors that require periodic brush replacement based on operating hours, the brushless configuration delivers consistent performance with minimal maintenance requirements in continuous monitoring applications.

Digital Timer Control

The integrated digital timer provides precise sampling period control with programmable start/stop functions. This EPA-recommended timer technology offers superior accuracy compared to mechanical timers and includes elapsed time indication for complete sampling documentation.

PM2.5 Size-Selective Sampling

The sampler utilizes a PM2.5 size-selective inlet that removes particles larger than 2.5 µm aerodynamic diameter while allowing fine particulate matter to pass through to the collection filter. The measurement process is considered to be nondestructive, and the PM2.5 sample obtained can be subjected to subsequent physical or chemical analyses.

Applications

Designed for ambient air quality monitoring including:

Non-regulatory PM2.5 monitoring studies
Institutional and academic research programs
Source assessment and characterization
Environmental impact studies
Background concentration monitoring

Calibration and Maintenance

PM10 High Volume Air Samplers should be calibrated upon installation, after any motor maintenance, once every quarter (three months), and after 360 sampling hours. The brushless motor design reduces maintenance frequency compared to brush-style motors while the MFC system provides built-in flow verification capabilities.
