Andair

What Andair does

Andair AG is a Swiss shelter technology company founded in 1968 and headquartered in Andelfingen, Switzerland. It designs and manufactures specialized equipment for civil protection shelters, with a portfolio spanning ventilation systems, NBC (Nuclear, Biological, Chemical) filtration units, explosion protection valves, EMP (Electromagnetic Pulse)-protected components such as doors and diesel generators, gastight shut-off valves, shock-resistant fans, acoustic and vibration damping systems, and shelter furnishing. Core technologies include explosion protection valves (types ESV 4, FC, KC-T and ESV San-100), ventilating installations (VA 150, VA 300, VA 2400), NBC filtration units including the Survivor 40 and mobile variants, gas filter cartridges (GF 600), and waveguide-style EMP grilles (type HC), with all products type-tested and approved by Switzerland's SPIEZ LABORATORY and manufactured under ISO 9001:2015 certification.

The business model is anchored on one-time hardware sales of custom-engineered safety equipment sold directly to end customers — government civil defence authorities, armed forces, and industrial facility operators in oil & gas, petrochemical, and nuclear power sectors — through official procurement channels and direct enterprise contracts. Pricing is not publicly disclosed, and there are no recurring SaaS or service subscription components described; revenue is project-based. The company markets through a bilingual (German/English) corporate website and direct enterprise sales rather than broad-channel marketing. Andair is privately held with no disclosed institutional investors or subsidiaries; Michael Riedo serves as CEO and authorized representative. The company has equipped more than 3,000 large protected installations in over 55 countries since founding, establishing a global but selectively-distributed footprint in certified shelter infrastructure.

Direct peers

• MIK Group: German shelter technology and protective-equipment manufacturer supplying NBC filtration, ventilation, and blast-protection components to civil-defense authorities. Direct overlap with Andair's shelter-product portfolio across Europe.
• Camfil AB: Global air-filtration manufacturer producing HEPA, NBC, and gas filtration media and housings used in cleanrooms, defense shelters, and industrial ventilation. Comparable at the filtration-component and air-handling level.

Broad incumbents

• Drägerwerk AG & Co. KGaA: Large German safety-technology group with NBC filtration, respiratory protection, gas detection, and shelter-related products. Overlaps Andair's NBC and ventilation offering but operates a much broader portfolio.
• MSA Safety Incorporated: Global safety-equipment manufacturer supplying respiratory protection, gas detection, and fixed gas-monitoring systems used in shelters, industrial, and first-responder applications. Comparable in NBC protection but far larger and broader in scope.
• Avon Protection (Avon Rubber plc): Supplies military and first-responder respiratory protection, NBC respirators, and protective equipment. Comparable NBC filtration domain though focused on personal protection rather than shelter-installed systems.
• Honeywell International (Safety & Industrial): Global conglomerate offering respiratory protection, gas detection, and industrial safety solutions that overlap with Andair's NBC filtration and ventilation monitoring. Not shelter-specialized but competes for defense/civil-protection budgets.
• 3M Personal Safety Division: Provides respiratory protection, powered air-purifying respirators, and gas-mask cartridges. Overlaps with Andair's NBC filtration offering at the filtration-component level.

Emerging players

• BLÜCHER GmbH: German manufacturer of NBC protective equipment, filtration systems, and decontamination solutions. Narrower portfolio than Andair but highly specialized in NBC filtration for defense and civil-protection customers.

Others

• Köttermann GmbH & Co. KG: Manufacturer of laboratory furniture and safety fume hoods. Indirectly comparable where Andair supplies air-quality/ventilation components to laboratory and bio-safety facilities.

Regional players

• Bauer Spezialtiefbau / Bauer Group: Large German foundation/specialty construction group whose civil-engineering activities include hardened and underground structures. Represents a complementary rather than directly competing party in shelter infrastructure projects.
