The nitrogen generators described in this manual, thanks to its built in scroll-compressor, are able to provide
by itself the necessary quantity of compressed air to supply the N2 Membrane section and produce a stable
and safe flow of pure nitrogen at a setted pressure.
NGA CASTORE XS iQ SHI is also able to produce Dry Air combined with Nitrogen up to 40 l/min.
The appliances can be used in laboratories and/or light industrial environments.
