The TE-6070VFCX is a high volume air sampler engineered for precise 40 CFR Part 50, Appendix J compliant PM10 particulate monitoring. This EPA reference method provides for the measurement of particulate matter with an aerodynamic diameter less than or equal to 10 micrometers in ambient air over a 24-hour period for determining attainment and maintenance of National Ambient Air Quality Standards.

PLUS Technology Controller

The VFC PLUS (Volumetric Flow Control) technology uses a microprocessor-based controller with built-in ambient temperature and barometric pressure sensors for accurate, real-time flow control. The actual PM10 concentration can be calculated from the corrected concentration, using the average ambient temperature and barometric pressure during the sampling period. The PLUS controller automatically compensates for changing environmental conditions to maintain precise volumetric flow rates throughout the sampling period.

Key Specifications

Sample Type: PM10 particulate matter (≤10 µm aerodynamic diameter)
Power Configuration: 220V, 50Hz
Motor Type: Brushless design for extended service life
Timer: Digital with battery backup
Controller: VFC PLUS with microprocessor-based flow control
Built-in Sensors: Ambient temperature and barometric pressure

Digital Timer and Data Logging

The integrated digital timer provides straightforward programming for repeatable sampling periods with battery backup to maintain settings during power outages. The PLUS controller includes four comprehensive data logs capturing average, minimum, and maximum ambient temperature and barometric pressure, plus total ambient and standard flow measurements. Data retrieval is simplified through USB export capability for analysis and regulatory reporting.

Brushless Motor System

The brushless motor assembly delivers reliable, maintenance-free operation compared to traditional brush-style motors. This design eliminates carbon brush replacement, reduces electrical noise, and provides consistent performance over extended operational periods. The brushless configuration is particularly advantageous for continuous monitoring applications and remote site installations.

PM10 Size-Selective Inlet

The sampler uses a precision-engineered size-selective inlet that draws ambient air at a constant flow rate where suspended particulate matter is inertially separated into size fractions within the PM10 size range. This inlet design ensures accurate particle size separation according to EPA reference method specifications, collecting only particles with aerodynamic diameters of 10 µm or less.

Applications

The TE-6070VFCX serves ambient air quality monitoring networks, regulatory compliance monitoring, environmental impact assessments, and research applications requiring EPA-compliant PM10 data. The 220V, 50Hz power configuration makes this unit suitable for international installations and regions with 50Hz electrical systems.

Compatibility and Configuration Options

This sampler is part of the TE-6070 series family, available in multiple configurations including different power options (110V/220V), timer types (mechanical/digital), motor styles (brush/brushless), and controller technologies (MFC/VFC/VFC PLUS). The TE-6070VFCX specifically combines digital timing, brushless motor operation, and VFC PLUS flow control in a 220V, 50Hz configuration optimized for international deployment.
