Thumbnail Filmstrip of VFC for TSP Hi-Vol Air Sampler, 220V Brush Style Systems Images
The TE-10557TSPX Volumetric Flow Controller (VFC) delivers precise flow control for TSP high volume air sampling systems operating on 220-volt brush-style motors. This essential component maintains constant air flow during the sampling period as required by EPA specifications for TSP monitoring, ensuring accurate and compliant particulate matter collection.
Flow Control Technology
The VFC employs an orifice-based control mechanism that automatically compensates for filter loading and ambient conditions throughout the 24-hour sampling period. By maintaining constant volumetric flow, the controller eliminates the need for continuous flow rate recording to achieve accurate air volume measurements, simplifying operation while ensuring EPA compliance.
Key Specifications
- Voltage: 220V AC systems
- Flow Range: Maintains EPA-required flow rates between 39-60 CFM
- Configuration: Brush-style motor compatibility
- Includes: VFC orifice and calibration look-up table
Compatibility
Designed specifically for 220V brush-style TSP high volume air samplers. This controller integrates with Tisch Environmental's complete TSP sampling systems and is compatible with standard 8" x 10" filter assemblies. The VFC works in conjunction with continuous flow recorders and elapsed time indicators to provide comprehensive sampling documentation.
EPA Compliance
Engineered to meet EPA requirements for flow controlling mechanisms in TSP sampling systems as specified in 40 CFR Part 50, Appendix B. The VFC ensures sampling accuracy required for ambient air quality monitoring and maintains the precise flow velocities necessary for proper particulate collection efficiency.
Installation and Calibration
The complete VFC assembly includes the flow control orifice and manufacturer-supplied look-up table for system calibration. Calibration procedures follow EPA-approved protocols using conventional orifice-type flow transfer standards. Tisch Environmental recommends periodic calibration verification using NIST-traceable flow measurement standards to maintain sampling accuracy.
