About Döller Maschinen
Döller Maschinen (Absaugwelt24 GmbH), based in Dortmund, is a manufacturer-independent system provider for industrial extraction and compressed air technology. The company plans, designs, procures, installs and maintains mobile and stationary extraction systems for welding fume, laser and soldering smoke, grinding and fine dusts, metal chips, oil and emulsion mist as well as wood dust, paint mist and stone materials – with volume flows from a few hundred up to 50,000 m³/h. In addition, the company offers compressor technology from screw to piston compressors and boosters up to 40 bar including heat recovery, soundproof cabins in element construction, fire protection systems according to FprEN 16770:2016, piping systems, inspections according to BetrSichV as well as financing services. Customers can be found in metal and woodworking, in forging and switchgear construction, in the plastics (GRP/CFRP), chemical and stone processing industries as well as in paint shops. Via the online shop absaugwelt24.de, dust extractors, extraction tables, extraction arms, piping, filter media and accessories are sold; deliveries are made to Germany, Austria and Switzerland.
