VFC Motor Hold Down Ring with 8-Hole Pattern SKU: TE-5070-3

The TE-5070-3 is a clamp ring with an 8-hole pattern designed specifically for VFC (Volumetric Flow Controlled) motor housing assemblies. This precision-manufactured hold down ring secures the motor assembly within the VFC blower housing, providing critical structural support for high volume air sampling operations.

Function and Performance

The TE-5070-3 creates a secure mechanical connection between the motor assembly and the VFC aluminum blower housing. The 8-hole bolt pattern distributes clamping forces evenly around the motor perimeter, preventing vibration and ensuring reliable operation during extended sampling periods. This ring works in conjunction with the VFC flange gasket to create a properly sealed motor mounting system.

Compatibility

The TE-5070-3 is compatible with all Tisch Environmental VFC motor assemblies, including:

• 110V brush-style motors (TE-115923)
• 220V brush-style motors (TE-116111)
• Brushless VFC motors (TE-5070-BL series)
• VFC aluminum blower motor housing (TE-5070-2)

Installation Requirements

The TE-5070-3 must be used with the matching VFC flange gasket (TE-5070-1) to ensure proper sealing and prevent air leakage at the motor mounting interface. Always inspect both the hold down ring and gasket during motor assembly or replacement to verify proper alignment of all 8 bolt holes.

Applications

This hold down ring is an essential component for EPA-compliant ambient air monitoring systems using VFC technology. It supports continuous operation in TSP, PM10, and PM2.5 sampling applications where precise volumetric flow control is required for regulatory compliance.
