New Filter Fans
The successful LV/GV series has been improved and redeveloped. The main features are the new design, some detail revisions, the IP 55 solution, new fans for some models as well as the extended model range. The type designations are not changed and the new parts are compatible with the existing components.                                                                   

Extended model range
The model range has been extended by some models between the others (LV 405, 410 and 550) and by the new high performance top model LV 800. Today Rübsamen & Herr offers the wide-ranging series of filter fans on the market.

The new Design – distinctive and timeless
The shape of the front grille was redesigned. The plane surface with chamfered edges is insensitive against dirtying. We are well aware that we go without a trendy and short-living look. 

IP 55 solution
The filter fans and exhaust filters can be equipped with Z-line-filters with filter class F5 as an option.
Therewith the degree of protection IP 55 is reached. The IP 55 version fans are suited for outdoor application because of the UV-resistant front grilles.

Cover plate BV 400/500
The cover plate is needed if a cut-out must be closed afterwards, for example if a cooling unit is applied. The mounting cut-out is 223 x 223 mm, the same as for the medium sized fans LV/GV 4XX/5XX.
