TE-5005-8 Pressure Tap with Nut and Gasket for Hi-Vol Air Samplers SKU: TE-5005-8

The TE-5005-8 Pressure Tap with Nut and Gasket is a critical connection component for Tisch Environmental high volume air sampling systems. This pressure tap connects from the blower motor to the continuous flow recorder or manometer, enabling accurate flow measurement and monitoring during TSP, PM10, and PM2.5 ambient air sampling operations.

Technical Function

The pressure tap serves as the pneumatic connection point between the blower motor assembly and flow measurement devices. It enables continuous flow/pressure recording by providing a stable pressure signal proportional to the air flow rate through the system. The included nut and gasket ensure leak-free operation under the vacuum conditions created by the high volume air sampler.

System Compatibility

This pressure tap assembly is designed for use with Tisch Environmental TE-5005 Blower Motor Assemblies and connects to:

• TE-5009 Continuous Flow/Pressure Recorders
• Water manometers (TE-5030 30" models)
• Oil manometers (TE-5008)
• Electronic manometers and calibration equipment

Compatible with all Tisch Environmental high volume air samplers including TE-5000 series TSP samplers, TE-5100 series PM10 samplers, TE-5170 series VFC models, and TE-6070 series PM2.5 samplers that utilize TE-5005 blower motor assemblies.

Installation and Maintenance

The pressure tap installs directly onto the blower motor housing using the provided nut and gasket. Proper connection requires tubing from the pressure tap of the blower motor to the flow recorder or manometer. The gasket must be properly seated to prevent air leaks that could compromise flow measurement accuracy. Inspect the gasket periodically and replace if cracking or compression damage is observed.

Important: Never conduct leak tests with a manometer connected to the pressure tap, as liquid from the manometer could be drawn into the system and cause motor damage.

EPA Compliance Applications

This component supports EPA-compliant ambient air quality monitoring per 40 CFR Part 50, Appendix B for TSP sampling, ensuring accurate flow measurement critical for valid particulate matter concentration calculations. TSP samplers operate within 1.10 to 1.70 m³/min (39 to 60 CFM), requiring precise pressure monitoring to maintain EPA compliance.
