Product Details

I. Main Features:

1. Can replace high-pressure steel cylinders, making the laboratory safer.

2. Easy operation: just turn on the power switch, and the instrument produces gas with stable output pressure. The nitrogen, hydrogen, and system are equipped with flow display, which is more eye-catching and intuitive.

3. No electrolyte consumption: the electrolyte only plays a role in ion conversion and is not consumed, so only a small amount of distilled water lost through evaporation and electrolysis needs to be replenished.

4. Safe and reliable performance: incorporating the advantages of nitrogen, hydrogen, and air series generators and similar products, it is equipped with multiple protection devices, making it a safe, reliable, and convenient combination.

5. Long lifespan: can be used intermittently or continuously, with stable gas production and no easy attenuation.

6. High efficiency and energy saving: uses switching power supply to improve electrolysis efficiency. The working process is fully automatic, simple to operate, and easy for daily maintenance.

7. The nitrogen part adopts new double-purification technology, and the hydrogen part adopts a high-tower structure electrolysis separation cell.

8. Equipped with three-stage purification and two-stage pressure stabilization, facilitating observation of the instrument's working status and fault diagnosis.

9. Long lifespan, can be used continuously or intermittently, with stable gas production and no attenuation.

Features of the nitrogen-hydrogen-air integrated machine:
　　1. Laboratory instrumentation, can replace traditional high-pressure steel cylinders. The nitrogen-hydrogen-air integrated machine can be used alone or simultaneously; it can be used intermittently and is recommended for continuous use; the gas purity does not attenuate.
　　2. The domestic on-site nitrogen, hydrogen, and air three-gas generator AYAN-T300 is easy to operate: just turn on the power switch to produce gas, with stable output flow. The nitrogen and hydrogen systems are equipped with LED digital display, which is more eye-catching and intuitive.
　　3. The nitrogen-hydrogen-air integrated machine combines the advantages of generators and similar products, and is equipped with multiple protection devices, making it a safe, reliable, and convenient combination.
　　4. (1) The nitrogen part adopts new double-purification technology to improve purity, truly solving the problem of two gases and one cylinder in the laboratory;
　　(2) The hydrogen part adopts a high-tower structure electrolysis separation cell. The nitrogen-hydrogen-air integrated machine can store liquid, produce hydrogen, and discharge oxygen simultaneously. It has a large electrolysis area, low cell temperature, and higher purity, making it a replacement for plate-type electrolysis cells.
　　(3) The air part has the advantages of three-stage purification, two-stage pressure stabilization, and multiple protection.
　　5. Both the nitrogen and hydrogen systems of this instrument are equipped with anti-backflow devices to ensure no backflow occurs.
　　6. Daily use of the nitrogen-hydrogen-air integrated machine only requires replenishing distilled water.

Method for replacing purification tube packing
Check the color of the indicating silica gel in the purification tube through the observation window on the front of the instrument. It is recommended to replace the silica gel when two-thirds of it has changed color. When replacing, turn off the power, wait until the pressure indication drops to zero, then rotate the purification tube clockwise to remove it, unscrew the end cap counterclockwise, remove the absorbent cotton, and pour out the packing.
Users can perform drying treatment as needed; after replacing the packing (not too full), place new absorbent cotton inside the tube wall, screw on the end cap clockwise, then screw on the purification tube counterclockwise and check for leaks;
The activated carbon purification tube is located on the right side of the gas storage tank inside the instrument, made of stainless steel. It is recommended to replace the internal packing once a year. When there is no pressure, unscrew the tube body counterclockwise, then unscrew the end cap counterclockwise. The packing does not need drying and can be replaced directly with new material.
3. Maintenance of the electrolysis cell
For the domestic on-site nitrogen, hydrogen, and air three-gas generator AYAN-T300, it is recommended to replace the electrolyte once a year. Specific method: siphon out the electrolyte, rinse twice with distilled water, and then add new electrolyte according to the method for preparing electrolyte. 

1. The drying tube should be replaced regularly. When 50% of the indicating silica gel in the drying tube has changed color, the internal packing should be replaced. Replacement method: turn off the power and vent the system gas (pressure drops to zero). Rotate the purification tube in the direction indicated by the arrow to remove it, then unscrew the end cap of the purification tube and replace the silica gel desiccant.
2. Packing treatment method: bake the indicating silica gel in an oven at 120°C for 12 hours. Calcine the molecular sieve in a muffle furnace at 250°C-300°C for 24 hours. For the instrument's activated carbon purification tube, it is recommended to replace the internal activated carbon packing every 1000 hours.
3. When replacing the desiccant, care should be taken to place all the absorbent cotton into the tube to ensure no effect on the sealing end face, thereby ensuring a seal after the end cap is tightened. (Note: When filling the packing, it is forbidden to inject the packing material into the gas pressure tube to avoid blocking the gas path.)
4. When installing, tighten in the direction indicated by the arrow, and after starting, use soap solution to check for leaks and ensure sealing.
5. It is not allowed to arbitrarily wrap various sealing tapes on the threaded surface of the drying tube, otherwise it will cause the drying tube to crack and fail to seal.
6. The instrument consumes electrolyte during operation. Distilled water should be replenished regularly according to usage conditions to ensure the liquid level is between the upper and lower limit marks.
7. The instrument does not consume electrolyte solution during operation, but it is recommended to replace the electrolyte every six months. When replacing the electrolyte, first extract the waste electrolyte from the instrument, add distilled water, start the instrument, let the system clean the electrolysis system for about 5-10 minutes, extract the distilled water, and then add new electrolyte alkali solution.
8. The flow display value of the instrument is converted from the current applied to the electrolysis cell. It may have slight changes due to vibration. A display value change within ±10 is normal, but the flow supply can still be output stably.
9. The instrument panel has a drainage switch. It is recommended to press this switch to drain water during startup operation every week. The instrument itself has automatic drainage on startup. To avoid contamination, the drainage tube should always be connected to a liquid collection bottle.
10. If the air pressure needs to be readjusted, rotate the knob on the rear panel of the instrument. Clockwise rotation increases the output pressure, while counterclockwise rotation decreases it.
