VFC Flange Gasket with 8 Holes SKU: TE-5070-1

The TE-5070-1 is a precision-engineered flange gasket featuring 8 bolt holes, specifically designed for VFC (Volumetric Flow Controlled) motor assemblies in Tisch Environmental's high volume air sampling systems. This critical sealing component ensures airtight connections between motor housing components, preventing air leaks that could compromise sampling accuracy and flow control performance.

Function and Installation

The gasket creates a reliable seal at the motor flange interface within VFC blower assemblies. Proper sealing is essential for maintaining the precise volumetric flow control required for EPA-compliant ambient air monitoring. The 8-hole configuration matches the bolt pattern of VFC motor housings, ensuring accurate alignment and consistent sealing pressure across the entire flange surface.

Compatibility

The TE-5070-1 gasket is compatible with the following VFC motor assemblies:

• TE-5070 110V Brush Style Motor Assembly for VFC systems
• TE-5070X 220V Brush Style Motor Assembly for VFC systems
• TE-5070-2 VFC Motor Housing (8-bolt hole configuration)
• VFC motor assemblies used in TSP, PM10, and PM2.5 high volume air samplers

This gasket works in conjunction with other VFC assembly components including motor spacer rings (TE-5005-5) and motor cushions to create a complete sealing system.

Maintenance and Replacement

Regular inspection of flange gaskets is critical for maintaining system integrity. Tisch Environmental recommends checking that all gaskets are in good shape and seal properly during routine maintenance procedures. Replace gaskets if they show signs of compression set, cracking, or deterioration that could allow air leaks. Proper gasket condition is essential for accurate flow measurements and regulatory compliance in ambient air monitoring applications.

Applications

The TE-5070-1 gasket supports EPA-compliant air quality monitoring in VFC-equipped samplers designed for Total Suspended Particulate (TSP) monitoring per CFR 40 Part 50 Appendix B. VFC systems provide precise flow control across varying filter loading conditions, making reliable sealing components like this gasket essential for maintaining sampling accuracy throughout extended monitoring periods.
