12x12x4 PrecisionCell II Filters. PrecisionCell II filters dramatically reduce in-line space requirements when compared to 12″ - 36″ deep filters. Their nominal 4″ depth makes a convenient fit for most installations. High efficiency filtration, which is often required for acceptable Indoor Air Quality, may now be selected by the design engineer without having to compromise space.
PrecisionCell II filters are especially suitable for VAV systems and are designed to operate at face velocities up to 625 FPM. Two styles are available: standard box style and an optional headered (top and bottom) version that are manufactured with a header for use with existing side access housings. PrecisionCell II filters are UL 900 Classified.
