Aluminum Cover for 4 inch Filter Holder SKU: TE-1008-9

The TE-1008-9 aluminum cover serves as the top closure component for the TE-1008 4-inch filter holder used in dual sampling module (PUF) systems. This precision-machined aluminum cover ensures proper sealing and secure retention of particulate filter media during high volume air sampling operations.

Technical Design

The cover integrates with the dual chambered aluminum sampling module's upper chamber which supports airborne particulate filter media in a circular filter holder. The aluminum construction provides corrosion resistance for outdoor sampling applications while maintaining dimensional stability under varying environmental conditions.

Compatibility

This cover is specifically designed for the TE-1008 complete 4-inch filter holder assembly and works with related components including:

• TE-1008-1 4-inch hold down frame
• TE-1008-2 4-inch filter holder body with stainless steel screens
• TE-1008-5 Teflon gaskets (2 required)
• TE-1008-8 4-inch filter holder gasket (silicone, 4.5" OD)

Installation and Maintenance

Installation involves securing the cover with the hold down ring and swing bolts after positioning clean 102mm diameter glass fiber filter media between Teflon gaskets. Regular maintenance requires cleaning any dirt buildup around the module and filter holder. The aluminum construction allows for repeated cleaning cycles without degradation.

Applications

Compatible PUF sampling systems operate in accordance with U.S. EPA Method TO-4 for determination of organochlorine pesticides and polychlorinated biphenyls in ambient air. Additional applications include EPA Method TO-4A, TO-9A, and TO-13A sampling protocols for comprehensive ambient air quality monitoring and pollutant assessment.
