The TE-6070BLX-2_5 is a high volume air sampler specifically configured for fine particulate matter having an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM2.5) collection in ambient air. Designed for non-regulatory institutional studies and research applications requiring reliable, high-volume PM2.5 sampling capabilities.

The Mass Flow Controller uses a hot wire anemometer to maintain a steady flow rate throughout the sampling period. The hot wire anemometer probe is inserted into the flow stream and automatically adjusts the motor speed as the filter begins to collect particulate, compensating for increasing pressure drop as the filter loads with particles. This active flow control maintains consistent sampling conditions throughout the 24-hour sampling period.

Key Specifications

Flow control: Mass Flow Controller (MFC) with hot wire anemometer probe
Timer: 7-day mechanical timer for dependable start/stop control
Motor: Brushless design for reduced maintenance and extended field service life
Power: 220V, 50Hz configuration
Filter size: 8" x 10" quartz microfiber filters
Sampling rate: Maintains constant volumetric flow throughout sample period

System Components and Operation

The sampler consists of a sample air inlet, downtube, particle size separator (impactor), filter holder assembly, air pump and flow rate control system, flow rate measurement device, ambient and filter temperature monitoring system, barometric pressure measurement system, timer, outdoor environmental enclosure, and the necessary control systems for autonomous operation. The PM2.5 size-selective inlet uses precision-engineered impaction surfaces to separate and collect only particles 2.5 µm and smaller on the quartz filter.

Compatibility and Configuration

This model represents the PM2.5 configuration of the Tisch Environmental Model TE-6070 PM10 High-Volume Air Sampler platform, specifically adapted for fine particulate collection. The BLX designation indicates brushless motor with 220V 50Hz power configuration and MFC flow control. Compatible with all standard 8" x 10" quartz microfiber filters designed for high-volume PM2.5 sampling applications.

Maintenance and Field Operation

Brushless style motors do not use motor brushes or require maintenance. They are higher in cost and do not have any emissions. The mechanical timer provides reliable scheduling without the complexity of digital controls, making this configuration well-suited for remote monitoring locations where simplicity and reliability are priorities. The anodized aluminum shelter protects all components from environmental conditions during extended field deployment.

Applications

Designed for institutional research, air quality studies, and non-regulatory ambient monitoring where measurement of the mass concentration of fine particulate matter is required. Suitable for environmental impact assessments, health studies, and source apportionment research. The measurement process is considered to be nondestructive, and the PM2.5 sample obtained can be subjected to subsequent physical or chemical analyses.
