The success story of Willibrord L\u00f6sing Filtertechnik e. K. began in October 1955. Since then, we have focused on high-quality products with the aim of being a reliable partner to our customers for all filtration solutions.
The cornerstone of our product range was laid with products from the manufacturer Hengst Filterwerke. Over time, several renowned filter manufacturers were added to our range, including Air Refiner (USA), Argo Filter (Germany), Fairey Arlon B.V. (Netherlands), Diamond Filtri (Italy) and Donaldson Inc. (USA) \u2013 and many more. <\/p>\n

The 1970s saw our operations expand, with two new branches opening in Germany and a further one in Austria. This meant that even back then, we were able to support customers across a wide area with filter products and our expertise. <\/span><\/p>\n After German reunification in 1990, another branch was opened near Leipzig. Because we have always strived to meet the requirements of our customers, we have continuously adapted to their needs and to the market. Today, we are proud to offer a complete product range with over 11,000 items in stock \u2013 true to our motto: \u201cEverything from a single source\u201d. <\/p>\n <\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/loesing-filter.de\/wp-content\/uploads\/2025\/01\/OelHyKlei-4700×2400-1.png” title_text=”OelHyKlei-4700×2400-1″ force_fullwidth=”on” align_tablet=”center” align_phone=”center” align_last_edited=”on|desktop” _builder_version=”4.27.4″ custom_margin=”|||” custom_padding=”|||” border_radii=”|24vw|||24vw” border_color_all=”gcid-96852864-b3c6-4bdf-9c73-962f9799e1a4″ border_width_left=”2vw” border_color_left=”gcid-96852864-b3c6-4bdf-9c73-962f9799e1a4″ box_shadow_style=”preset4″ box_shadow_horizontal=”-30px” box_shadow_spread=”-10px” box_shadow_color=”gcid-4f44057d-3375-40d1-ac4e-66bbfe98898d” global_colors_info=”{%22gcid-96852864-b3c6-4bdf-9c73-962f9799e1a4%22:%91%22border_color_all%22,%22border_color_left%22%93,%22gcid-4f44057d-3375-40d1-ac4e-66bbfe98898d%22:%91%22box_shadow_color%22%93}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ use_custom_gutter=”on” gutter_width=”2″ specialty=”on” padding_top_2=”20px” padding_right_2=”5%” padding_2_tablet=”0px|10%||10%||true” padding_2_phone=”” padding_2_last_edited=”on|tablet” _builder_version=”4.16″ inner_width=”100%” inner_max_width=”100%” use_custom_width=”on” width_unit=”off” custom_width_percent=”100%” global_colors_info=”{}”][et_pb_column type=”1_3″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/loesing-filter.de\/wp-content\/uploads\/2025\/05\/Liquid-Overhead-Full-Family.jpg” title_text=”Liquid Overhead Full Family” force_fullwidth=”on” align_tablet=”center” align_phone=”center” align_last_edited=”on|desktop” _builder_version=”4.27.4″ custom_margin=”|||” custom_padding=”|||” animation_style=”slide” animation_direction=”right” animation_intensity_slide=”5%” hover_enabled=”0″ border_radii=”||30px|15vw|” border_color_all=”#2f8cff” border_width_bottom=”2vw” border_color_bottom=”gcid-96852864-b3c6-4bdf-9c73-962f9799e1a4″ box_shadow_style=”preset3″ box_shadow_vertical=”30px” box_shadow_blur=”80px” box_shadow_spread=”-30px” box_shadow_color=”rgba(102,141,186,0.7)” locked=”off” global_colors_info=”{%22gcid-96852864-b3c6-4bdf-9c73-962f9799e1a4%22:%91%22border_color_bottom%22%93}” sticky_enabled=”0″][\/et_pb_image][\/et_pb_column][et_pb_column type=”2_3″ specialty_columns=”2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” padding_tablet=”0px|10%||10%||true” padding_last_edited=”on|tablet” custom_padding__hover=”|||” padding_phone=”0px|10%||10%||true”][et_pb_row_inner _builder_version=”4.16″ global_colors_info=”{}”][et_pb_column_inner saved_specialty_column_type=”2_3″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.27.4″ text_font=”Almarai|300|||||||” text_font_size=”16px” text_line_height=”2em” header_font=”||||||||” header_2_font=”Montserrat|300|||||||” header_2_text_color=”#212d3b” header_2_font_size=”40px” header_2_line_height=”1.5em” max_width=”600px” custom_margin=”|||” custom_margin_tablet=”0px|50px||50px” custom_margin_last_edited=”off|desktop” custom_padding=”|||” global_colors_info=”{}”] A special chapter in our company history began in 1982 with the launch of our own filter production.

In 1995, we established a subsidiary in Florida, USA \u2013 marking yet another milestone in our development. <\/p>\n
By 2000, production volumes had grown to such an extent that we had to move to larger facilities. Since then, we have been certified according to DIN EN ISO 9001 and meet the highest quality standards. <\/p>\nSend us a message<\/strong><\/h2>[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ text_font=”Almarai|300|||||||” text_font_size=”22px” header_font=”||||||||” text_orientation=”center” background_layout=”dark” global_colors_info=”{}”]
