Thumbnail Filmstrip of TE-1004-7 Motor Back Plate for PUF Motor Assembly Images
The TE-1004-7 Motor Back Plate is a critical structural component of the TE-1004 PUF Blower Motor assembly used in Tisch Environmental's Polyurethane Foam (PUF) high volume air samplers. This aluminum back plate provides secure mounting and proper alignment for the blower motor within the PUF sampler housing.
System Integration
PUF systems are designed to meet the requirements described for sampling using US EPA method TO-4A, TO-9A, and TO-13A for the collection of volatile organic compounds and airborne pesticides. The motor back plate ensures proper motor positioning within the sampler housing to maintain consistent airflow characteristics essential for EPA-compliant sampling.
Technical Function
The back plate secures the motor assembly to the PUF housing and provides structural support for the high-volume blower motor during operation. The flow is pulled through a critical orifice with either a brushless or brush-style vacuum blower motor assembly that operates at flow rates between 125-250 lpm. Proper motor mounting via the back plate is essential for maintaining these flow specifications.
Compatibility
The TE-1004-7 back plate is specifically designed for use with:
- TE-1004 PUF Brush Style Blower Motors (110V and 220V versions)
- TE-1004-BL and TE-1004X-BL Brushless Motor Assemblies
- TE-1004-3 PUF Motor Housing assemblies
- TE-1004-1 Motor Flange components
This back plate works in conjunction with the TE-1004-2 Flange Gasket to ensure proper sealing and vibration isolation within the motor assembly.
Applications
Essential for PUF samplers used in:
- EPA TO-4A pesticide and PCB monitoring
- EPA TO-9A dioxin and furan sampling
- EPA TO-13A PAH determination
- Semi-volatile organic compound collection
- Ambient air quality monitoring programs
Installation Notes
When replacing the motor back plate, ensure proper alignment with the motor housing and verify that all mounting hardware is secure. The back plate must be properly positioned to maintain motor alignment and prevent excessive vibration that could affect sampling accuracy. Always disconnect power before servicing motor assembly components.
