Oil Absorbent Ring for PM2.5 Inlet SKU: TE-6001-2.5-9

The TE-6001-2.5-9 Oil Absorbent Ring is a consumable component designed specifically for the PM2.5 Size Selective Inlet used in high-volume air sampling systems. This oil-absorbent media prevents the accumulation of oil droplets within the PM2.5 inlet during operation, ensuring consistent particle separation performance and maintaining sampling accuracy.

Technical Function

The oil absorbent ring captures oil aerosols that may be present in ambient air or generated by the sampling system's mechanical components. By absorbing these oil particles, the ring prevents contamination of the PM2.5 particle separation process and maintains the integrity of collected particulate samples on the filter media.

Compatibility

This oil absorbent ring is designed for use with:

• TE-6001-2.5-I PM2.5 Size Selective Inlet for High Volume Air Sampler
• TE-6001-2.5-8 Oil Absorbent Ring Hold Down (retention component)
• TE-6001-2.5-11 Oil Absorbent Ring Holder (mounting assembly)
• TE-6001-2.5 Retro-Fit Kit to convert High Volume PM10 Inlet into PM2.5 Inlet

Maintenance Requirements

Regular inspection and replacement of the oil absorbent ring is essential for maintaining optimal PM2.5 inlet performance. The replacement frequency depends on ambient oil concentrations and sampling duration. Tisch Environmental recommends monitoring the ring for oil saturation and replacing as needed to prevent breakthrough that could affect particle collection efficiency.

Application

PM2.5 reference and equivalent method samplers use specially shaped inlets followed by impactors for EPA-compliant ambient air quality monitoring under 40 CFR Part 50, Appendix L. The oil absorbent ring ensures these systems maintain their designated particle size separation characteristics throughout extended sampling periods.
