PM2.5 Hi-Vol Air Sampler, PLUS Controller, Brush Motor, 220V SKU: TE-PM2.5-HVPX

PM2.5 Hi-Vol Air Sampler, PLUS Controller, Brush Motor, 220V

The TE-PM2_5-HVPX is a high volume air sampler configured for PM2.5 particulate collection at 2.5 µm or less for non-regulatory studies and institutional research. This sampler draws ambient air at a flow rate of 40 cfm through a PM2.5 size selective inlet consisting of 40 stainless steel nozzles that allow only 2.5 µm particulates to get deposited on the filter.

PLUS Controller Technology

The PLUS controller features a microprocessor-based flow control system with built-in ambient temperature and barometric pressure sensors for accurate, real-time flow monitoring. The hot wire anemometer probe is inserted into the flow stream and automatically adjusts the motor speed as the filter begins to collect particulate. The controller includes a digital timer with battery backup, multiple elapsed time indicators, four data logs, and USB export capability for data retrieval.

Key Features

• Flow Rate: 40 CFM (1.13 m³/min) through PM2.5 size-selective inlet
• Filter Size: 8" x 10" (20.3 x 25.4 cm) quartz or glass microfiber
• Power Configuration: 220V, 50Hz
• Motor Type: Brush-style motor for proven field reliability
• Timer: Digital timer recommended by US EPA allows for 1 in 3, 1 in 6, 1 in 7, and custom sampling schedules with internal battery backup and LCD screen
• Data Logging: Four separate data logs capture average, minimum, and maximum ambient temperature and barometric pressure

Sampling Performance

The PM2.5 size-selective inlet uses 40 stainless steel nozzles to trap larger particulates inside the inlet while allowing smaller PM2.5 particulates to continue through and be collected on the 8" x 10" quartz filter paper. PM2.5 particulates are particularly hazardous to human health as they can work their way into lungs during respiration and be absorbed into the bloodstream.

System Components

PM2.5 particulate samplers are built with motor, timer, flow controller, elapsed time indicator, outdoor aluminum shelter, and pressure recorder. The anodized aluminum shelter is designed to allow particulate matter to be drawn onto the filter from all directions, with rugged construction that withstands the elements with minimal maintenance.

Applications

This sampler is designed for environmental monitoring professionals conducting non-regulatory PM2.5 studies, institutional research, and ambient air quality assessments. The collected samples can be analyzed for mass concentration determination and chemical speciation studies. The high volume collection capability makes it suitable for trace-level pollutant analysis where larger sample volumes are required for detection limits.

Regulatory Context

While this sampler is configured for non-regulatory monitoring, PM2.5 measurement methods are governed by 40 CFR Part 50, Appendix L for regulatory compliance applications. The required sample period for PM2.5 concentration measurements shall be 1,380 to 1500 minutes (23 to 25 hours).
