Highly Corrosion Resistant NucFil®-019 HCR
(UNS-N06022 Alloy) Drum Vent Filter

The NucFil®-019 HCR drum vent filter is highly resistant to chemical corrosion from chlorinated solvents and strong acids, including HCI and nitric, due to the combination of its UNS-N06022 Alloy housing and a patent pending press fit mechanical seal that eliminates adhesive or cements such as RTV. The only two components to the filter are chemically inert porous carbon-carbon and chemically resistant UNS-N06022 Alloy.

•	Nuclear Filter Technology's NucFil®-019 HCR highly corrosion resistant drum vent filter is engineered to provide the same hydrogen diffusivity as our original NucFil®-019 design, plus provide excellent chloride and acid corrosion resistance.

•	Filters are certified carbon-carbon HEPA drum vent filters that meet WIPP WAC and TRUPACT-II SAR Appendix 1.3.5 requirements:
		•	H2 permeability exceeds 20 E-06 mol/s/mol fraction- a 5X filter
		•	Greater than 99.97% removal of 0.45 micron DOP
		•	Greater than 200 ml/min air flow capacity at <1.0" W.C.

•	The carbon-carbon composite filter media:
		•	Resists acid and chloride corrosion
		•	Is 70% porous
		•	Is unaffected by extreme temperatures.


•	Chemical resistance testing conducted in Nuclear Filter Technology's R&D Laboratory:

		•	Tested in 1 liter desiccators with 12 molar (concentrated) hydrochloric acid (HCI) vapors.

		•	Accelerated tests:

				•	Vapor Pressure of 12 molar HCI at room temperature produces a vapor concentration of about 100,000 ppmv of HCI

				•	HCI concentration in desiccators kept constant; not decreasing concentration over time

				•	Worst case expected in TRU waste drums is a vapor concentration of about 30 ppmv of HCI

				•	Accelerated test by more than 3,000 times expected challenge (HCI concentration)

				•	100% immersion of filter sample in vapor, not just one side in vapor and the other in cleaner air.
