Panel filter / synthetic / flat / pleated - PFA/4, PFA/5 series
PFA/4 - PFA/5 panels have a high filtration efficiency, limited pressuredrop and high dust holding capacity.
They are fitted with a humidity-proof, punched cardboard frame; the filter medium is a blend of synthetic and cotton fibers, pleated and held into position by stretched aluminum grids. The medium is fixed to the frame through a very strong anti-aging glue.
PFA/4 - PFA/5 panels come with two different frame thickness: 48 and
98 mm, which have pressure drop levels between 80 and 120 Pa,
according to the models.
The pleated panels offer a filtration surface which is double or three times the flat panels of the same size. Thanks to their high filtration efficiency, strong construction, high dust holding capacity and high manufacturing quality these filters are widely used in conditioning and ventilation plants.
They offer a long operating life with very low fan energy consumption
levels.
