"LOM BAG" VH FIBERGLASS BAG  FILTERS

They are high efficiency filters composed of a series of pockets through which the air to be treated passes. These pockets are made in glass microfibres media supported on the air outlet side by a nonwoven coverig, and are properly clamped to a support frame. Strong seams ensure the good seal of 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 in air treatment units and ventilation plants either as final filters or as pre-filters to absolute filters in order to make their life longer.
FEATURES	Four different type are available: VH45, VH65, VH85 and VH95. The following table shows the filtration class according to EN 779 and the nominal capacities with the pertaining initial resistance for some standard sizes. Of course filters with different number of pockets, different frontal and/or depth dimensions are available. See the table.
INSTALLATION & SERVICE	It is advisable to foresee a prefiltration stage before these filters. The LOM-BAG filters can be installed into proper holding frames having frontal access and usually designed to fit any possible prefilters.
