Top Plate for PM2.5 Size Selective Inlet SKU: TE-6001-2.5-1

The TE-6001-2.5-1 Top Plate is a critical component of Tisch Environmental's PM2.5 size selective inlet system, which is made up of 40 stainless steel nozzles that allow only 2.5µm particulates to get deposited on the filter. This precision-machined top plate serves as the upper assembly component that houses and protects the multi-nozzle arrangement essential for accurate PM2.5 particle separation.

Function and Design

The top plate provides the structural foundation for the PM2.5 inlet's multi-nozzle configuration. As particulates travel through the size selective inlet at 40 CFM, the larger particulates are trapped inside of the inlet as the smaller PM2.5 particulates continue to travel through the PM2.5 inlet and are collected on the 8" x 10" quartz filter paper. The top plate's precision design ensures proper airflow distribution across all 40 nozzles for consistent particle separation performance.

Compatibility

This top plate is specifically designed for use with:

• Tisch Environmental PM2.5 high volume air samplers
• TE-6001-2.5-I PM2.5 size selective inlet assemblies
• Non-FRM PM2.5 sampling systems operating at 40 CFM flow rates
• Compatible with gasket TE-6001-2.5-2 for proper sealing

Installation and Maintenance

The top plate requires periodic inspection and cleaning to maintain optimal performance. Tisch Environmental PM2.5 samplers are non-Federal Reference Method instruments designed for non-regulatory sampling and institutional studies. Regular maintenance of inlet components, including the top plate, ensures consistent particle size separation and prevents sampling artifacts that could compromise data quality.

For proper installation, use with the appropriate gasket (TE-6001-2.5-2) and securing hardware. The precision machining of this component requires careful handling during maintenance procedures to preserve the critical dimensional tolerances needed for accurate PM2.5 sampling.
