PUF Motor Spacer Ring for PUF Motor Assembly SKU: TE-1004-8

The TE-1004-8 PUF Motor Spacer Ring is a critical component for polyurethane foam (PUF) motor assemblies used in high volume air sampling systems for semi-volatile organic compounds. This precision-machined spacer ring ensures proper alignment and spacing within PUF sampler motor assemblies, which are designed to collect airborne particulate and vapor contaminants including volatile organic compounds, pesticides, and semi-volatile organics.

PUF samplers operate in compliance with EPA methods TO-4A, TO-9A, and TO-13A for the determination of toxic organics in ambient air. The motor spacer ring maintains critical mechanical tolerances within the motor assembly, ensuring consistent airflow characteristics and proper sealing between components during high volume sampling operations.

Technical Function

The spacer ring provides precise dimensional control within the PUF motor assembly, maintaining proper clearances between rotating and stationary components. PUF systems typically operate between 125-250 lpm and use either brush style or brushless vacuum blower motor assemblies with critical orifices to control and calculate ambient flow rates. The TE-1004-8 ensures these motor assemblies maintain their calibrated performance specifications.

Compatibility

This spacer ring is designed specifically for PUF motor assemblies and is compatible with:

• TE-1004 110V PUF Brush Style Blower Motors
• TE-1004-BL 110V Brushless Motor Assemblies
• TE-1004X-BL 220V Brushless Motor Assemblies
• Related PUF motor assembly components including TE-1004-1 Motor Flange, TE-1004-2 Flange Gasket, TE-1004-3 PUF Motor Housing, and TE-1004-7 Motor Back Plate

Installation Notes

The spacer ring must be installed in the correct orientation and position within the motor assembly stack-up. Proper installation ensures optimal motor performance and prevents mechanical interference during operation. For brush style motors, proper spacing is critical for brush contact and current conduction, while brushless motors require precise clearances for electromagnetic field generation.

Applications

PUF samplers are classified as high volume air samplers used for collecting airborne volatile organic compounds, particulate matter, and airborne pesticides. These systems are well suited for environmental monitoring applications requiring high volume VOC sampling, including ambient air quality monitoring, source emission assessment, and long-term environmental studies where reliable, repeatable system configuration is essential.
