TE-6001-2.5 Hi-Vol PM10 to PM2.5 Retrofit Conversion Kit SKU: TE-6001-2.5

The TE-6001-2.5 retrofit kit converts existing high volume PM10 air samplers into PM2.5 reference method samplers using EPA-designed WINS (Well Impactor Ninety-Six) technology. This conversion kit provides a cost-effective solution for facilities needing PM2.5 monitoring capabilities without purchasing an entirely new sampling system.

How It Works

The WINS impactor operates downstream of the existing PM10 inlet at a volumetric flow rate of 16.7 L/min. The single-stage, single-jet impactor uses inertial separation where particles greater than 2.5 µm aerodynamic diameter are captured on a 37 mm diameter glass fiber filter immersed in low volatility oil. Particles 2.5 µm and smaller pass through to be collected on the main filter for gravimetric analysis.

Key Specifications

• Cutoff diameter (D50): 2.5 ± 0.2 µm
• Operating flow rate: 16.7 L/min (1.0 m³/hr)
• 37 mm diameter glass fiber impaction substrate
• Compatible with 8" × 10" filter media

Kit Components

The TE-6001-2.5 includes all components needed for PM10 to PM2.5 conversion:

• WINS impactor assembly with oil reservoir
• PM2.5 inlet top plate and gasket
• Acceleration nozzles and nozzle plate adapter
• Screen and nozzle plate components
• Mounting hardware (bolts and nuts)
• WINS oil for impaction substrate

Compatibility

This retrofit kit is designed for Tisch Environmental high volume PM10 samplers in the TE-6000 series. The conversion allows the sampler to operate in multiple configurations - PM10 reference method or PM2.5 equivalent method - with proper labeling to indicate current configuration. Compatible with both mass flow controlled (MFC) and volumetric flow controlled (VFC) sampler platforms.

Maintenance Requirements

The WINS impactor oil reservoir and glass fiber substrate require replacement every five sampling days to prevent particle overloading that affects cutoff diameter accuracy. Regular inspection of O-rings, gaskets, and nozzle components ensures proper seal integrity and sampling performance.

Applications

Essential for ambient air quality monitoring networks transitioning to PM2.5 compliance monitoring. Supports EPA PM2.5 Federal Reference Method (FRM) requirements for regulatory monitoring programs. Ideal for research applications requiring fine particulate characterization and source assessment studies where higher sample volumes are needed for detailed chemical analysis.
