OxygenFree An2Di - Nitrogen generator, a modern, environmentally friendly device for self-disinfection of books, documents, and archival materials. Designed for museums, libraries, and cultural institutions, it effectively protects collections without the use of chemicals.
How it works
The generator produces nitrogen from the air, creating an oxygen-free environment that eliminates all pest stages, from eggs to adults. The process lasts 21-25 days and is completely safe for the disinfested objects.
Ecologically and safely:
The device does not use toxic substances, and nitrogen returns to the atmosphere at the end of the process. The absence of chemicals means no risk to people or the environment.
Easy, cheap and DIY:
Disinsection is carried out in sealed EVOH film balloons, which are oxygen-resistant and reusable. The process can be performed anywhere, without the help of external companies.
The complete set includes:
Nitrogen generator with control panel,
100 l tank,
pulse sealer, EVOH film, compressor, valves and hoses.
Key technical parameters:
Working output: 560 l/min at 1 bar • Working pressure: 10 bar • Power: 3 kW • Noise level: 68 dB • Power supply: 230 V / 50 Hz • Weight: ~55 kg
