Nuclear Overview Brochure
AAF offers a wide range of nuclear grade pre-filters with a range of filtration efficiencies to ensure we can offer a suitable combination of filters in any air filtration system in a nuclear power plant. Pre-filters serve to protect and extend the life of HEPA filters, removing larger particles from the airstream. They can also be used as central filters in systems where HEPA filtration is not required.
Our nuclear grade pre-filter product range begins with our entry-level nuclear grade MetaNet. This washable metal pre-filter has a filtration efficiency of up to G2. For added protection, the nuclear grade ChevroNet has an efficiency up to G4 and has been supplied to nuclear power plants around the world. Finally, if you are looking for maximum protection then the nuclear grade VariCel filters have a high dust holding capacity, low airflow resistance and a filtration efficiency up to F9, the perfect complement to AAF’s AstroCel III NG HEPA filter.
