‘Click-and-Fit’ filter fan assemblies offer IP55 protection
Click-and-fit filter fan assemblies from Pfannenberg now include versions
that offer IP54 or IP55 environmental sealing. These assemblies protrude
just 6mm outside the enclosure, allowing easy replacement of the closed
pore foam filter element. Air throughput depends upon the level of
sealing; the smallest unit fitted with 350g/m3 IP54 material has a
throughput of 56m3/h, while the IP55 rated filter has a throughput of
36m3/h.
