 |  |  1. Nitrogen Separation Membranes (UBE N2 Separator)
These modules use a polyimide hollow fiber membrane that provides higher permeability to oxygen than nitrogen to easily obtain a 97.0-99.9% pure nitrogen gas from compressed air, at roughly the same pressure as the supplied air.
●Applications
Oil well injection, marine on-board use, laser cutting, plastic molding, tire filling, analysis instruments, tank and piping purging, lead-free solder, aircraft fuel tank filling, other

a) Materials of bodies on NM-815T and NM-1015 are stainless steel equivalent for SUS304.
b) An initial N2 product volume has 1.15-times or more the value of the table.
c) NM-1015 is cartridge type. Value of dimensions and weight are only on the cartridge.
2-2. Recovery rate
Air Supply conditions: Pressure 0.7 MPaG, Temperature 25°C | N2gas purity [%] and generated volume [Nm3/h] | | 99 | 98 | 97 | 96 | 95 | | 26 | 34 | 39 | 43 | 47 |
2-3. Required amount of compressed air
(1) Theory to calculate amount of compressed air:
a) for NM-B01A - C10F (refer to Table in para. 2-1 of page 2)
= Product Flow Rate [Nm3/h] / (Recovery [%] / 100) X 1.15(*1) X 1.2(*2)
