Compact HEPA Filter

The Compact HEPA filters are mainly used for the clean rooms to control the particulates that are larger than 0.3μm. The common depth is 70mm/90mm and adopts mechanical compression seal. But the seal effect isn’t as well as gel seal, so there’s a tendency to be replaced by gel sealed compact HEPA filter. There are two kinds of sealing: CR hand-made sealing and PU automatic foaming. Considering the factor of performance and efficiency etc, most of LENGE products produced by PU automatic foaming which will be much better.
