RP-I Three Dihedral rigid

SAGICOFIM RP-I high efficiency rigid bag filters with a larger filtration surface are tested in accordance with EN 779/2012 and are EUROVENT certified.

Efficiency classes: M6-F7-F8-F9.

These high efficiency rigid bag filters are a technologically innovative way of filtering fine dust particles.

By using specific materials and a special construction design, they are a valid alternative to soft bag versions.

In the standard RP-I version, the filters have a new 3-dihedral shape which, due to having optimised certain construction features, enables a reduction in pressure drops and the fan’s energy consumption.

High dust-accumulation energy-saving versions (HC) are also available, as well as a high temperature (HT) version.
