Oil Absorbent Ring Hold Down for PM2.5 Hi-Vol Air Sampler SKU: TE-6001-2.5-8

The TE-6001-2.5-8 Oil Absorbent Ring Hold Down secures the oil absorbent ring within PM2.5 high volume air samplers, ensuring proper positioning and operation of the size-selective inlet system. This component is essential for maintaining the "perfect absorber" mechanism that prevents particle bounce and reentrainment in the inlet's collection system.

Technical Function

The hold down assembly maintains precise positioning of the TE-6001-2.5-9 Oil Absorbent Ring during sampling operations. The oil-coated surface eliminates particle bounce and reentrainment in the PM2.5 size-selective inlet, ensuring accurate fractionation of particles ≤ 2.5 µm aerodynamic diameter. The secure positioning prevents displacement during the high airflow conditions typical in continuous ambient air monitoring.

Compatibility

This hold down component is designed specifically for use with:

• TE-6001-2.5-9 Oil Absorbent Ring
• TE-6001-2.5-I PM2.5 Size Selective Inlet
• PM2.5 high volume air samplers operating at 40 cfm (1.13 m³/min)
• Related components including TE-6001-2.5-11 Oil Absorbent Ring Holder

Maintenance Requirements

Regular inspection ensures proper seating and alignment of the oil absorbent ring system. The hold down should be checked during routine inlet maintenance when the absorbent ring is serviced or replaced. Verify secure positioning before each sampling period to maintain EPA compliance for ambient PM2.5 monitoring applications. Use with TE-6001-2.5-15 Wins Oil for proper inlet operation.

Applications

Essential component for ambient air quality monitoring stations conducting PM2.5 particulate sampling in accordance with NAAQS requirements. Used in non-Federal Reference Method samplers for non-regulatory sampling and institutional studies. Critical for maintaining sampling accuracy in environmental monitoring programs, research applications, and air quality assessment studies.
