Brass Thumb Nuts for TE-3000 Filter Media Cartridge (Set of 2) SKU: TE-3000-3

The TE-3000-3 brass thumb nuts are essential fastening components for the TE-3000 Filter Media Cartridge system used in TSP, PM10, and PM2.5 high volume air sampling applications. These hand-tightened fasteners are designed for quick, tool-free assembly and adjustment, featuring a textured (knurled) surface that provides secure grip for easy installation and removal without wrenches.

Technical Operation

The brass thumb nuts secure the TE-3000 Filter Media Cartridge to high volume air sampler filter holders, allowing the entire cartridge assembly to be removed to a convenient location for filter changes. They work in conjunction with the rubber gasket system to create an airtight seal around the filter periphery, with the thumb nuts being tightened to hold the base plate securely in position. This tool-free operation enables fast maintenance changeovers and repeatable adjustments ideal for frequent filter replacement schedules.

Material Benefits

Brass construction provides an attractive finish while being non-magnetic and spark-resistant, making these thumb nuts well-suited for air sampling equipment applications. Brass performs optimally in dry indoor environments and controlled sampling conditions. The thumb nuts are highly reusable components designed for repeated installation and removal, with durable construction that maintains threading integrity through multiple sampling cycles.

System Compatibility

The TE-3000-3 thumb nuts are specifically designed for use with the TE-3000 Filter Media Cartridge and TE-3000-2 aluminum hold down frame. The TE-3000 Filter Media Cartridge facilitates filter changing by keeping contamination off clean filters and protects collected particulate from being disturbed during transit. The complete system holds 8" x 10" filter paper for high volume air samplers.

Maintenance Guidelines

Installation requires no special tools — simply hand-tighten onto compatible mounting hardware using the textured gripping surface. Tisch Environmental recommends periodic inspection of thread condition and replacement when wear becomes evident. The thumb nut design makes them ideal for frequent access applications where quick removal and reinstallation is required.

Each set includes two brass thumb nuts to secure both sides of the filter cartridge hold down frame, ensuring proper sealing and filter positioning for accurate air sampling results.
