FILTERING CELLS "DF" TYPE |
|
|
They are cheap, disposable filtering cells at medium efficiency. The
filtering media, with density growing from the air inlet side to the air
outlet side, is composed of continuous filament glass fibers and it is
supported front and back by two metal grids which are fastened to a cardboard
frame. |
|
|
APPLICATIONS |
They are used for fan-coil, air treatment units, warm air generators,
ventilation equipement of machines and as prefilters to filters having higher
performances (like LOM-BAG pockets filters, rigid pockets or activated carbon
filters). The high dust storage capacity of fiberglass media make them
suitable should high dust charge be present. |
|
FEATURES |
The filtration class of these filters, according to EN 779 Standards,
is G 3. See the
Table. |

INSTALLATION & SERVICE |
The DF filters can be installed
into C-shaped guides or into holding frames at frontal access. Replace the
