We support you from the very start of the project in designing and developing the solution that best suits your needs. Our wide range of products offers many options for adjusting both the installation depth and the maximum pressure losses required.<\/p>\n

We supply all leading manufacturers in Europe (see References<\/a>) and have over 500,000 ventilation grilles in service worldwide in rail vehicles.<\/p>\n

In many cases, we also design and manufacture the entire component in which the ventilation grille (weather protection grille<\/b>, FSA filter<\/b>) is installed, such as front flaps, side panel flaps, and side panel doors. The bonding technology, which has been used for these components for many years and is now certified, enables a low weight and prevents the surface irregularities that can sometimes occur with welded components.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”50px”][\/vc_column][\/vc_row][vc_row bg_type=”bg_color” bg_override=”full” bg_color_value=”#F2F2F2″][vc_column][vc_column_text css=””]Krapf & Lex Ventilation Grilles (Weather Protection Grilles, FSA Filters)<\/b>[\/vc_column_text][vc_row_inner css=”.vc_custom_1777275611933{margin-top: -20px !important;}”][vc_column_inner width=”1\/2″]
