Overview

The TE-6070VBLXZ is a high volume air sampler configured for PM10 particulate matter sampling in compliance with EPA requirements for ambient air quality monitoring. This system collects particulate matter with an aerodynamic diameter less than or equal to 10 micrometers (µm) over 24-hour sampling periods for determining attainment and maintenance of 40 CFR Part 50, Appendix J reference method standards.

Volumetric Flow Control Technology

The VFC (Volumetric Flow Controlled) system uses a critical orifice with a predetermined hole diameter to control flow rate. The critical orifice is drilled and calibrated to allow only the predetermined flow rate to pass through the filter. The motor operates wide open while the critical orifice maintains a constant flow rate, providing reliable performance across varying field conditions without active feedback control.

Key Specifications

Power: 220V, 60Hz electrical configuration
Motor: Brush-style motor for proven field reliability
Timer: 7-day mechanical timer with on/off trippers
Flow Rate: 36-60 ft³/min through PM10 size-selective inlet
Filter Size: 8″ × 10″ quartz filter paper

Mechanical Timer Operation

The system includes a 7-day mechanical timer for simple, dependable start and stop control. Recognized by its bright yellow timer dial, the mechanical timer uses a series of on/off trippers to set the sampling schedule, providing straightforward operation without requiring digital programming or battery backup systems.

Brush Motor Design

Brush-style motors use carbon motor brushes to conduct current within the electric motor. They are economical and provide proven performance but require routine motor brush replacement. This configuration offers reliable operation with predictable maintenance intervals for field sampling applications.

Compatibility and System Integration

This sampler is part of Tisch Environmental's modular PM10 sampler family. The TE-6070VBLXZ shares core components with other configurations including alternative timer options (digital), motor types (brushless), and power configurations (110V, 220V 50Hz). The system is housed in an anodized aluminum outdoor shelter designed for continuous field operation.

Applications

This sampler is designed for EPA-compliant ambient air quality monitoring to determine attainment and maintenance of national ambient air quality standards for particulate matter. Applications include routine environmental monitoring at permanent sites, source assessment studies, and compliance monitoring where the non-destructive measurement process allows collected PM10 samples to be subjected to subsequent physical or chemical analyses.
