Compressed air from compressor is separated by polymer membrane when it passes through the Hakko FX-780/FX-781. N2 gas goes to the Hakko FX-791 via tube, and other air constituents are discharged outside.
It utilizes the different permeability of each air constituent. N2 has lower permeability than oxygen or carbon dioxide.

Connect the tube of compressor to the valve “AIR IN”. If connecting to the valve “N2 OUT”, N2 separation performance may decrease and nitrogen gas is not discharged from HAKKO FX-791.
*The picture on the right shows the connection sample of small-capacity type HAKKO FX-780.
Supply compressed air 0.3 to 0.7MPa to HAKKO FX-780 or FX-781. 0.5MPa is recommended.
NoteIf compressed air 0.2MPa or less is supplied, the performance may decrease and if 0.8MPa or more, HAKKO FX-780/FX-781 may be damaged.
In order to supply compressed air of 0.3 to 0.7MPa, followings are required.
Perform periodical maintenance of compressor, air dryer, air filter and water filter to keep HAKKO FX-780/FX-781 in good condition.
Check and clean compressor, air dryer, air fiilter and water filter periodically in accordance with the manufacture’s recommendations.
The life time of HAKKO FX-780/FX-781 is approx. 5 years under the condition of the 8-hours a day / 240 days a year operation, by the use in good condition with periodical maintenance.
NoteWhen the HAKKO FX-780 or HAKKO FX-781 end of life, the high polymer membrane needs to be replaced. As it costs as the same price as purchasing a new one, we would recommend purchasing instead of replacing.

HAKKO FX-791
Gas flow rate adjustment in 0.25L/min increments makes it easy to select the appropriate gas flow rate.
Turn the gas flow control knob to change flow rate.
Use the gas discharge valve to open or close N2 gas.
Operate the flowmeter in accordance with the usage note above.
NoteIf Gas Flow Control Knob is used to open/close the N2 gas, the unit may be broken.
It is possible to set up N2 System using your HAKKO soldering station. You can find out N2 soldering iron for your station.
