The TE-6070VBL-2.5 is a high volume air sampler engineered for PM2.5 particulate matter collection according to EPA reference methods for fine particles with aerodynamic diameters ≤ 2.5 µm. This configuration combines volumetric flow control (VFC) with a brushless motor system to deliver reliable field performance for non-regulatory monitoring and institutional research applications.

Volumetric Flow Control Operation

The VFC system uses differential pressure measurement across the PM2.5 size-selective inlet to maintain consistent volumetric flow rates despite variations in filter loading and environmental conditions. This approach ensures accurate sample volume calculations throughout the 24-hour sampling period, providing more consistent mass concentration data compared to constant mass flow systems.

Key Specifications

Power: 110V, 60Hz single-phase
Motor: Brushless design reduces maintenance requirements
Flow Control: VFC (Volumetric Flow Controlled)
Timer: Mechanical 7-day programmable timer
Sample Type: PM2.5 fine particulate matter
Filter Size: 8" × 10" (20.3 × 25.4 cm)

PM2.5 Size-Selective Inlet

Equipped with a PM2.5 size-selective inlet designed to collect particles according to 40 CFR Part 50, Appendix L specifications for PM2.5 reference method sampling. The inlet uses cyclone or impactor technology to remove particles larger than 2.5 µm aerodynamic diameter while allowing fine particles to pass through to the filter.

Brushless Motor Advantages

The brushless motor eliminates carbon brush replacement, reducing routine maintenance compared to brush-style motors. This design provides consistent performance over extended field deployments with lower maintenance frequency, making it ideal for remote monitoring locations or continuous operation studies.

Compatible Applications

Non-regulatory PM2.5 ambient air monitoring
Research studies requiring high-volume sample collection
Source apportionment and chemical speciation sample preparation
Urban air quality assessment
Industrial hygiene and occupational exposure monitoring

Shelter and Installation

Housed in an anodized aluminum outdoor shelter with weather protection for electronic components. The shelter includes mounting provisions for secure field installation and access panels for routine maintenance and filter changes. Compatible with standard meteorological tower mounting systems.

Alternative Configurations

This sampler is part of the TE-6070 series, available in multiple configurations including different motor types (brush/brushless), timer options (mechanical/digital), power specifications (110V/220V), and flow controllers (MFC/VFC). For PM10 sampling requirements, see TE-6070 PM10 configurations.
