Compact Filters are often used as second filter stage in the supply air, either as last filter stage for comfort applications or as second prefilter stage for clean process applications. Compact filters need less space (depth) in air handling systems than bag filters: Opakfil ES is a A+ compact filter with very low energy consumption. Opakfil ST is a compact filter with low energy consumption.
