HEPA FILTERS
They are desinged, manufactured and tested under a Nuclear Quality Assurance Program meeting all requirements of ASME NQA-1 and 10CFR50 App. B. They also meet the requirements of ASME N509 and are qualified to ASME AG-1 (Formerly MIL-F-51068) and to UL 586. Capacity of up to 1500 CFM in a variety of sizes

Type II - Reusable Type 304 filters meet the requirements of ASME AG-1 and N509. They are filled with impregnated carbon that absorb radioactive lodides and other gases. Each Type II tray is rated for 333 CFM |
Type IV - This carbon filter is a BIBO type rated for 1,000-1,250 CFM |
Type III - A flexible system in which the carbon can be replaced without removing the tray or filter. Good for systems 2,000-30,000 CFM |

Walk-In Filter House - For systems up to 30,000 CFM. |
Side Access TSC - Designed for smaller systems and confined spaces. The AAF TSC housing is in use in over 75% of the nuclear power plants in the US today. |
Absorbent Test Canisters - They are used to determine the operating life remaining in a given bed of absorbent. Since it is not practical to take samples from an absorbent bed, small canisters are piped up in parallel to the main beds to pass a proportional amount of air flow and periodically removed from the system and sent for analysis of remaining life. |
