Bulgaria has emerged as a critical manufacturing hub in Southeast Europe, particularly within the automotive, electronics, and pharmaceutical sectors. As cities like Sofia, Plovdiv, and Varna continue to expand their industrial footprint, the necessity for high-standard indoor air quality (IAQ) and specialized filtration has never been higher.
Compliance with European Union regulations, such as EN 1822 for high-efficiency filters (EPA, HEPA, ULPA) and ISO 16890 for general ventilation, requires rigorous testing protocols. Bulgarian factories are no longer just looking for equipment; they are seeking technological partnerships that provide information increment and verifiable data to compete in the global market.
Our Air Filter Test Machines are engineered to bridge the gap between manufacturing output and stringent EU compliance, offering local Bulgarian enterprises the same level of precision found in the world’s leading metrology labs.
Supporting the Thrace Economic Zone and Sofia Tech Park with localized technical documentation and hardware integration.
