Evac AG

What Evac AG does

Evac AG is a privately held Swiss specialty manufacturer founded in 1973 in Buchs, Switzerland, by Heinrich Fend and now headquartered in Grabs (with a planned relocation to purpose-built premises in Gams). The company designs, develops, and manufactures precision vacuum sealing components spanning the full vacuum-to-pressure spectrum, covering ultra-high vacuum through 300 bar overpressure and temperatures from -271°C to +450°C (up to +1000°C for quartz variants). Its product portfolio is organized around four proprietary connection systems — CeFiX® (patented area-pressing EUHV system, invented 2002), ISO Tapered™ (one/two-screw quick connection, invented 1995), KF chain-clamp (invented 1993), and sTeRIc-clamp™ (metal-free, sterilizable connections for pharmaceutical and food & beverage) — together with chain clamps, flanges, seals, fittings, and adapters available across more than 500 active part numbers.

Evac serves enterprise customers in semiconductor manufacturing (PVD, CVD), science and research (particle accelerators, nuclear), aerospace and space (ISRO Mars Orbiter, JAXA asteroid sample return, lunar missions), medical and pharmaceutical, food and beverage, and railways. Marquee reference customers include CERN (100,000 metal seals for the LEP collider, 1987), Fermilab, JAXA, ISRO, and the PHARAO atomic-clock project, indicating deep penetration in mission-critical, qualification-locked applications. Customers access products via a 3D-enabled online configurator, downloadable STP files, and a global sales network comprising two wholly-owned subsidiaries in Japan and the USA and an authorized representative network covering 12 markets across Europe, Asia, the Middle East, and North America.

Evac's business model is direct B2B hardware sales of standardized catalog components plus custom-engineered sealing solutions, with quote-based pricing and no public list price. Standard products ship within 14 working days; bespoke orders carry longer lead times. The company is privately held by founder-family interests under CEO & President Brigitte Blanco-Fend (appointed 2006), with no disclosed external funding, no parent company, and no public listing. It is presently investing in facility expansion (new Gams headquarters, new Japan office), a 2024 brand refresh, and Website 2.0 with multilingual support.

Products and services

• CeFiX® Systems Evac's patented ultra-high vacuum connection system (NW16-NW250) using an area-pressing mechanism instead of traditional knife-edge compression. Delivers leakproof seals with <10E-11 mbar vacuum performance, 200,000+ reuse cycles, -271°C to +450°C temperature range and overpressure resistance up to 300 bar. Used by semiconductor OEMs, particle physics labs and aerospace programs.
• KF Systems Quick-release vacuum connection system (NW10/16 to NW63) using chain clamps with elastomer or aluminum edge-type seals, supporting vacuum levels up to 10E-9 mbar and peak pressures up to 50 bar across a -271°C to +450°C temperature range. Used for rough to high vacuum general-purpose applications.
• ISO Tapered™ Systems Proprietary quick-connection system (NW80-NW250, custom up to NW700) that requires only 1-2 screws compared to 8 for traditional ISO-K. Available in stainless steel and glass (Duran® and quartz), operating from -271°C to +350°C with overpressure up to 20 bar. For high-vacuum process and research applications.
• sTeRIc-clamp™ Systems Metal-free, gap-free, fully sterilizable vacuum connection system (NW8-NW80) with zero deadspace, manufactured from SUS316L stainless steel and compliant with ISO 2852 and ISO 1127.
