PM10 Quick Thumbnut Set - 4 Wing Nuts for 16.67 LPM EPA FRM Inlet Assembly SKU: TE-PM10-QT

The TE-PM10-QT Quick Thumbnut Set enables rapid assembly and disassembly of the upper inlet section on 16.67 L/min EPA FRM PM10 inlets without tools. This 4-piece wing nut assembly set with socket head screws replaces standard hex bolts to streamline field maintenance and filter changeouts on PM10 monitoring systems.

Technical Design

Each wing nut assembly combines a thumb-operated wing design with a socket head screw for secure, hand-tightenable connections. The thumbnut design maintains proper seal integrity on the inlet upper section while allowing quick access for routine maintenance. Compatible with all 16.67 L/min EPA reference method PM10 inlets that follow the 40 CFR Part 50, Appendix L specifications.

Key Specifications

• Quantity: 4 wing nut assemblies per set
• Material: Corrosion-resistant metal construction
• Thread compatibility: Standard PM10 inlet mounting threads
• Torque: Hand-tightening achieves proper sealing force

Compatibility

Works with any EPA FRM PM10 inlet operating at 16.67 LPM, including:

• TE-PM10-D inlet assemblies
• Standard louvered PM10 inlets per EPA specifications
• BGI PM10 inlet systems
• All EPA-designated reference method PM10 samplers

Installation and Maintenance

Replace existing hex bolts by removing with appropriate wrench, then installing thumbnut assemblies by hand. Tighten wing nuts firmly to ensure proper gasket compression and inlet seal integrity. Inspect threaded components during routine inlet cleaning to ensure smooth operation. The wing design allows technicians to perform inlet disassembly without carrying tools into the field.

Applications

Essential for field operations requiring frequent inlet access for:

• Filter cassette replacement in PM10 monitoring programs
• Inlet cleaning and maintenance procedures
• Impactor stage inspection and cleaning
• EPA audit preparation and compliance verification
