What Separation tech does

FST GmbH Filtrations-Separations-Technik is an independent, owner-managed German manufacturer of components and systems for compressed air treatment and technical gas purification. Founded in 2009 and headquartered in Essen-Kettwig with manufacturing in Netphen-Deuz, the company employs more than 40 specialists across manufacturing, sales, and administration. FST's product portfolio covers the full compressed-air treatment chain: nitrogen generators, five dryer types (adsorption, refrigeration, membrane, dew-point booster), compressed-air filters and filter elements, water separators, oil-vapor activated carbon adsorbers, compressed-air aftercoolers, breathing-air purification systems for industrial and medical use, and complete condensate-treatment systems (drains and oil-water separators). The company is differentiated by deep in-house production extending to raw materials (sheets, tubes, castings) and by special-engineering capability for systems up to 70 tonnes, 4,000 mm pipe diameter, and 1,000 bar pressure, realized through its strategic co-location with partner W&Z Rohrsystem-Technik GmbH.

The business operates a hybrid go-to-market model combining direct field sales, organized by German postal-code regions and country-specific export managers, with a Fachhändler specialist dealer network served by a dedicated portal containing a product-equivalence database and an online adsorption-dryer sizing tool. Revenue is generated through hardware sales of standard equipment, custom special-engineering projects, service kits (SEDAPAC, SEDAFILL, SEWAPAC), spare parts, accessories, and professional services including on-site commissioning, maintenance, and training delivered globally. Customer segments span industrial manufacturing (primary), food technology, chemical and pharmaceutical, medical and healthcare, and process industries, served across more than 50 countries in EMEA, the Americas, Asia-Pacific, the Middle East, and Scandinavia.

FST holds an unusually comprehensive portfolio of international pressure-vessel and quality certifications (ASME U-STAMP, NBBI, KGS, China SCOPE Level A1, Standards Australia AS 1210, DNV-GL, TÜV NORD HP0, DGRL Modules D/D1 and H/H1, DIN EN ISO 3834-2, DIN 2303, ISO 9001:2015) and its experts participate in ISO, PNEUROP, and VDMA standards committees. The General Director is Peter Wiebelhaus, with a management board covering domestic sales, technical operations, export sales and marketing, and HR/accounting. Revenue is not publicly disclosed.

Functional benefit

Brands

• W&Z Rohrsystem-Technik: Strategic partner company specializing in production of steel pipelines, pressure vessels, and plants. Located at same site as FST in Netphen-Deuz.

Products and services

• Nitrogen Generators On-site nitrogen generators that produce N2 from compressed air, eliminating the need for purchased nitrogen cylinders and avoiding supply bottlenecks. Targeted at industrial facilities requiring their own nitrogen supply.
• Compressed Air Dryers Five types of compressed air dryers (Adsorption DPS/DTS series, Refrigeration, Membrane, and Dew Point Booster) that remove condensation water from compressed air systems to ensure operational continuity. Achieves pressure dew points down to -70°C for demanding applications.
• Compressed Air Filters Industrial filters including coarse, fine, and ultra-fine filters (W, V, ZN, XN, XXN, A, CA, ST, STPL, SMPL, D grades), water separators (FCA, FWS, FMA, FMS series), and replacement filter elements ensuring compressed air purity for all ISO 8573-1 classes.
• Oil Vapor Activated Carbon Adsorbers Activated carbon adsorption systems (DSS and DSW series) that bind oil vapor to activated carbon pellets, reducing oil vapor content to residual oil levels of 0.003 ppm or less for oil-free compressed air, meeting ISO 8573-1 Class 0-1 purity requirements.
• Compressed Air Aftercoolers Air-cooled (HAO-RA) and water-cooled (HWO-A) aftercoolers that reduce compressed air inlet temperature (from 120°C down to 9°C above ambient in air-cooled models) and moisture content, improving downstream dryer efficiency.
• Breathing Air Purification Systems Industrial (DPS BI) and medical (DPS BM) breathing air systems providing germ-free compressed air compliant with DIN EN 12021 for industrial applications and European Pharmacopoeia standards for medical use.
• Condensate Treatment Systems Complete condensate management including automatic (CDF), electronic level-controlled (CDE-L), time-controlled (CDE-T), and manual (CDM) condensate drains, plus DIBt-certified oil-water separators (CSQ, CSJ, CSW series) for environmentally compliant condensate disposal meeting German federal water act (WHG) §7 requirements.
• Special Engineering Custom-designed compressed air systems beyond the standard portfolio, including large dryers, complete plants, special materials (e.g., stainless steel), alternative energy sources, and entire skid systems. Capabilities up to 70 tonnes weight, 4,000 mm pipe diameter, and 1,000 bar pressure.
• Service Kits and Spare Parts Maintenance packages including SEDAPAC desiccant packages, SEDAFILL desiccant packages, and SEWAPAC oil-water-separator maintenance kits, plus accessories and retrofit solutions (dew point sensors SP-ESH420, changeover controls, start-up devices) for all FST product lines.

Broad incumbents

• Kaeser Kompressoren: German-headquartered global compressor and compressed air treatment manufacturer. Competes with FST in dryers, filters, and condensate handling while also serving as a major compressor supplier whose installed base creates pull-through demand for treatment equipment.
• Parker Hannifin (Industrial Gas Filtration): Global motion and control incumbent offering compressed air and gas filtration, drying, and condensate treatment products through its Industrial Gas Filtration division. Overlaps with FST on filters, dryers, and condensate separators, but competes from a much larger installed base and product breadth.
• Donaldson Company: Large, diversified industrial filtration incumbent with a dedicated Compressed Air & Gas Filtration product line covering filters, dryers, and sterile filtration. Competes head-on with FST in filter elements and compressed air treatment, but as part of a much broader filtration portfolio.
• CompAir: European-headquartered compressor and compressed air treatment manufacturer offering oil-free and oil-lubricated compressors plus downstream filtration and drying equipment. Comparable to FST in the integrated compressed air system proposition.
• Atlas Copco (Compressor Technique): Global compressor OEM whose Compressor Technique business spans compressors, dryers, filters, nitrogen generators, and condensate treatment. FST's products are largely complementary accessories that often pair with Atlas Copco compressors, making it both a competitor (in dryers/filters) and an ecosystem partner.
• Ingersoll Rand: Global compressor and flow control incumbent offering dryers, filters, and nitrogen generation alongside its compressor portfolio. Competes with FST across most compressed-air treatment categories but from a significantly larger corporate footprint.

Direct peers

• Zander Aufbereitungstechnik: German manufacturer of compressed air treatment systems — adsorption and refrigeration dryers, filters, condensate treatment, and gas generation. Closely comparable to FST in product scope, Germany-centric manufacturing base, and industrial customer focus.
• Beko Technologies: German-headquartered specialist in compressed air treatment and condensate management, with overlapping product categories including adsorption and refrigeration dryers, filters, condensate drains, and oil-water separators. Closest direct peer to FST given similar Germany base, mid-market size, and Fachhändler-style distribution model.
• Pneumatech: Specializes in compressed air treatment — dryers, filters, nitrogen generators, and condensate management — serving industrial customers globally. Direct competitor to FST across the same core product categories, with similar standards-based marketing (ISO 8573-1) and dealer-led distribution.
• Ultrafilter International: Compressed air filtration specialist offering compressed air filters, sterile filtration, and condensate treatment with pan-European distribution. Highly comparable to FST in filtration, sterile air, and condensate management, and a frequent competitor in the German Fachhändler channel.
