AAF Nuclear Line Card
AAF Nuclear Grade Carbon Adsorbers remove gaseous radioactive iodine from the air stream in the form of elemental iodine (I2) or organic iodine (CH3I) by adsorption in nuclear reactor filtration systems. The charcoal adsorbent can be impregnated to improve its adsorptivity for radioactive iodines/iodides.
AAF can supply carbon adsorbers in three different filter types. In each case the adsorbent will need to be replacement at various intervals depending on plant conditions for each individual system. Speak to AAF for more details.

Fully compliant to latest standards
Type II Carbon Adsorbers are reusable 304 stainless steel filter trays that meet the requirements of ASME AG-1 Section FD and N509. The trays are reusable and refillable. Each tray is loaded with impregnated carbon that adsorb radioactive iodides and other gases.
The Type III Carbon Adsorber is a flexible system in which the carbon can be replaced without removing the tray or filter. The Type III is seismically qualified and proven for over 30 years. The design includes access doors for simplified maintenance, as well as temperature sensors and deluge pipe connections for fire protection.
The Type IV Carbon Adsorber is a Bag In/Bag Out (BIBO) type nuclear filter. Available in several standard sizes, the Type IV can be filled with appropriate adsorbent to capture any absorbable contaminant. The Adsorber is constructed with an 18-gauge, 304 Stainless Steel frame with a 26-gauge perforated screen.
