Nuclear Grade VariCel

Nuclear grade high efficiency pre-filter

Nuclear grade VariCel pre-filters are a series of medium and high efficiency rigid cell side disposable filters for removal of atmospheric dust and particulate from nuclear power plant air streams. These filters have low initial resistance, high dust holding capacity and a choice of three efficiency ranges: 60-65%, 80-85% or 90-95% particle removal efficiency.

VariCel pre-filters are designed to extend the life of AAF’s AstroCel I HEPA filters or can be used in a separate duct or line mounted unit where HEPA efficiency is not required. VariCel nuclear grade pre-filters can be installed for either upstream or downstream service requirements.
