Synthetic fiber bag filters
|
 |
G3 - G4 - F5 - F6 - F7 - F8 |
| They are medium and high efficiency filters composed of a series pockets through which the air to be treated passes. These pockets are made of synthetic fibers filtering media and are properly clamped to a support frame. Strong seams or edge weldings ensure the good sealing of the pockets. The property of these filters is the high filtering surface (proportional to the depth of the bags and their number). | ||
| APPLICATIONS | They are used either as final filters or as prefilters to high efficiency filters for air treatment units and ventilation plants. Their high dirt storage capacity makes them suitable should high dust charge be present. |
| FEATURES | Their self-supporting capability ensures them to bear any working discontinuity. The following table shows the filtration class according to EN 779 for the available types, and the nominal capacities with the initial resistance for some standard available sizes. See the table below. |
| INSTALLATION & SERVICE | They can be installed into proper holding frames having frontal access and usually designed to fit any possible prefilters. It is advisable to replace these filters once having reached a resistance of 250-300 Pa. |
|
Synthetic media offers lower resistance than fiberglass at the same air flow rate. The following table shows the filtration class according to EN 779 for the available types, and the nominal capacities with the initial resistance for some standard available sizes. |

| Capacities comprised between the 75% and the 125% of the mentioned ones are allowed for a good performance of the filters. Approximately it is possible to consider, inside this range, a linear correspondence between resistance and capacity. The limit working temperature is of approx. 90°C. Filters with different number of pockets, different frontal and/or depth dimensions are available. |
