MPL panel filters are ussually used in HVAC units, where there is not enough space for a pocket filter.
For our MPL filters we only use high performance synthetic media with integrated NANOfibre technology and rigid metal frames.
PLT and PLT XL panel filters are ussually used for general applications in HVAC units as prefilters or as the main filters, where there is not enough space for a pocket filter.
For our pleated panels we use only high performance selfsupporting synthetic media, which we glue to the rigid metal frames.
