Steam air sterilizer for aqueous solutions
Overcome the pressure challenge in sterilizing aqueous solutions, effectively preserving container integrity and product quality with precise control of thermal and pressure conditions.

Sterilizes and Preserves Liquid Formulations
The Steam Air Sterilizer – FOA Series by Fedegari is a fully customizable autoclave designed for rigorous sterilization requirements in the pharmaceutical, biopharmaceutical, food, and cosmetic industries. Its unique approach to counterpressure sterilization allows for precise control of temperature and pressure, ensuring the integrity of liquid formulations in sealed containers like large volume parenterals, pre-filled syringes, and canned foods. The system is capable of processing diverse loads, such as injectable antibiotics, hyaluronic acid serums, COVID-19 vaccines, and canned green beans, emerging dry and ready for subsequent production steps.
Equipped with the Thema4 process controller, the FOA Series integrates seamlessly into SCADA systems and complies with GAMP5 and 21 CFR Part 11, providing rapid validation while minimizing project risks. Its chamber, available in sizes ranging from 830 to 14,800 liters, is crafted from durable polished stainless steel with optional automatic sliding or semi-automatic hinged doors. Compliance with GMP, FDA, and multiple international standards ensures it meets the rigorous demands of global manufacturing environments.
The autoclave’s magnetic drive system reduces maintenance needs and guarantees 100% door tightness with Fedegari’s patented gaskets. Additionally, the innovative rotating drum feature accommodates suspensions and emulsions for enhanced heat transmission. With extensive customization options and expert engineering support, the FOA Series represents a highly adaptable solution for advanced sterilization challenges.
