Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for general stack gas particulate control
CO2 scrubbers without selective permeation are general gas cleaning equipment.
If configured as check valves with minimal separation
Membrane valve assemblies prioritize valve function over separation.
If for environmental emission monitoring gas samplers
Gas separation in monitoring instruments falls under Chapter 90.
