Thumbnail Filmstrip of Filter Holder for Mass Flow Controlled TSP High Volume Air Sampler Images
The TE-5004 Filter Holder is a critical component for mass flow controlled (MFC) Total Suspended Particulate (TSP) high volume air sampling systems. This stainless steel filter holder is designed for EPA-compliant TSP monitoring according to 40 CFR Part 50, Appendix B and accommodates standard 8" x 10" glass fiber filters for ambient air quality monitoring applications.
Design and Construction
The TE-5004 features robust stainless steel construction with an integrated probe hole collar that accommodates the hot wire anemometer probe used in MFC systems. The mass flow controlled design uses a hot wire anemometer probe inserted into the flow stream to automatically adjust motor speed as the filter begins to collect particulate, maintaining constant flow rates between 39-60 CFM throughout the sampling period.
Key Specifications
- Material: Stainless steel construction for weather resistance
- Flow rate range: 39-60 ft³/min (1.1 to 1.7 m³/min)
- Filter compatibility: 8" x 10" glass fiber filters (TE-G653)
- Probe hole: Integrated collar for MFC hot wire anemometer probe
- Gasket seal: Requires TE-5005-9 filter holder gasket
System Compatibility
The TE-5004 filter holder is designed to mount directly onto TE-5005 or TE-5005BL blower motor assemblies and is compatible with various MFC TSP sampling systems including:
- TE-5170 Mass Flow Controlled TSP High Volume Air Sampler
- TE-5170D-BL Brushless Motor MFC TSP Sampler
- MFC PLUS advanced TSP sampling systems
Installation and Maintenance
During installation, ensure the TE-5005-9 gasket is properly positioned between the filter holder and blower motor assembly, and orient the probe slot so incoming air passes through the hot wire anemometer probe. The filter holder requires TE-5018 gaskets (2 required) for proper 8" x 10" filter sealing. Regular inspection of gasket seals ensures accurate flow measurements and prevents sample contamination.
Regulatory Compliance
The aerodynamic design favors collection of particles up to 25-50 µm (aerodynamic diameter) depending on wind conditions, with collection efficiency meeting EPA specifications for particles of 100 microns (Stokes Equivalent Diameter) and less. This filter holder is an essential component for maintaining 40 CFR Part 50, Appendix B compliance in ambient TSP monitoring programs.
