Novair (Noxerior, NOVAIR group) NitroSwing is the new generation of modular PSA (Pressure Swing Adsorption) nitrogen generators that produce nitrogen on-site from compressed air, providing full autonomy and supply continuity with no recurring gas deliveries. They produce nitrogen at purities from 97% to 99.999% (residual oxygen from 3% down to 10 ppm), with flow of 1–265 Nm³/h and inlet pressure of 7–13 bar. The modular daisy-chain design lets capacity be increased at any time by simply adding modules — achievable without skilled personnel. All process components are made from non-corrosive materials (aluminium and stainless steel), and all models share common components, simplifying spare-parts management and maintenance. NITROPLUS, LASERPACK, and FOODPACK variants are also available.
