Filters for dust removal
Filter media for dust removal elements
Antistatic fi lter media
• High operational dependability without restricting the fi lters’ performance
• Retain their antistatic effect even with abrasive dusts or after being washed
in conformity with the washing instructions
• DMT test reports with electric surface and resistances to ground < 10 8 Ω
are on fi le
Full-area thermal bonding of the media involved creates very smooth nonwoven
surfaces. This means removal of the dust cake during cleaning is signifi cantly
better than with spunbonded nonwovens featuring punctiform or linear bonding.
FE 2506-sinus and FE 2507-sinus
• Save up to 35 % energy costs when operating your cartridge system. How?
Because the pleat grooving signifi cantly reduces the pressure drop, and the
material, thanks to its full-area thermal bonding, exhibits a considerably
smoother surface than do linearly embossed spunbonded nonwovens. A
plus that additionally has a benefi cial effect on the cleaning characteristics.
• You benefi t from an extended operational lifetime and reduced maintenance
costs.
• The patented pleat stabilization is thermally stable up to 90 °C and remains
mechanically stable even under alternating loads in the fi ltration and
cleaning phases.
• Increase your fi lters’ air fl ow rate, since the cartridges fi nished with FE 2507-
sinus offer a higher effective fi ltering area.
The measurements of the fractional arrestance effi ciencies prove it: FE 2507-
sinus meets the requirements of increasingly stringent dust emission guidelines.
This applies especially to arrestance of particles measuring < 2.5 μm, since the
fi ber structure is signifi cantly more homogeneous compared to spunbonded
nonwovens.
NEXX + NEXX as
• This patented microfi ber material has been developed specifi cally for the
stringent requirements obtaining in dust removal systems, and possesses
unique properties for surface fi ltration.
• Dusts can be quickly and easily washed off the microfi ber layer of the
Viledon ® NEXX fi lter medium.
• With Viledon ® NEXX clean-gas values of < 1 mg / m 3 can be lastingly
achieved.
• In comparison to needlefelts, Viledon ® NEXX requires around 50 % less
resources to produce. Coupled with the same (or an even higher) fi ltration
performance! This means you’re making a proactive contribution to protecting
the natural environment and ensuring sustainable resource-economy.
