Acceleration Nozzle Plate with Nozzles for PM10 Inlet SKU: TE-6001-2

The TE-6001-2 acceleration nozzle plate is a critical component of PM10 size-selective inlets that contains multiple acceleration nozzles designed to evacuate ambient air from the buffer chamber. The acceleration nozzles have critical diameters to provide the necessary changes in velocity to effect correct particle size fractionation within the impaction chamber.

Operating Principle

Particles are accelerated as they pass through the nozzles to an impaction chamber where particles greater than 10 microns aerodynamic diameter impact onto a greased impaction shim plate due to their larger momentum. The particles smaller than 10 microns are carried vertically upward by the air flow and down sixteen vent tubes to the standard 8 x 10-inch filter where they are collected.

Key Specifications

• Designed for 68 m³/h (40 CFM) flow rate operation
• Contains nine acceleration nozzles for proper particle fractionation
• Precision-manufactured for EPA-compliant PM10 monitoring

Compatibility

This acceleration nozzle plate is designed for use in PM10 size-selective inlets on Tisch Environmental high-volume air samplers. The PM10 high volume air samplers are designed according to the guidelines outlined in 40 CFR appendix J to part 50 and designated as a federal reference method sampler. Compatible with related PM10 inlet components including the gasket TE-6001-4 and individual PM10 acceleration nozzles TE-6001-3.

Maintenance Notes

Clean the nine acceleration nozzles with a bottle brush and wipe the surfaces clean with a damp cloth during routine maintenance. The acceleration nozzle plate and the use of the greased shim prevents re-entrainment of particles larger than 10 microns. Use factory specified replacement parts only as each PM10 sampler when properly configured is a United States Environmental Protection Agency (U.S. EPA) Designated Reference Method.

Applications

Essential for EPA-compliant ambient air quality monitoring of PM10 particulate matter. PM10 high volume air samplers are federal reference method (FRM) instruments designed to collect ambient particulate matter with an aerodynamic diameter of 10µm or less, using a size selective inlet to separate out particulate matter larger than 10µm. Used in environmental monitoring networks, industrial hygiene assessments, and regulatory compliance monitoring programs.
