Friendly Reminder: PGH-2000B Pure Water FilterAirGenerator, eliminates alkali addition. It features compact size, lightweight, high conversion efficiency, and sufficient gas output, making it a substitute for Qing.GasAn ideal upgrade and replacement product for steel cylinders.

I. Working Principle

PGH-2000BqingGasThe generator electrolytic cell employs the most advanced international solid polymer electrolyteqing technology available today, ensuring the producedqingNitrogenOxygen content less than 0.1ppm; it uses pure water as the electrolyte and titanium metal as the electrodes. Upon applying electricity, the cathode produces...GasAnode produces oxygen. Oxygen is vented.GasAfter entering the air-water separator, the water is separated, followed by cold drying and dehydration, and then fully dried through the drying tube before being output from the exhaust port. This instrument employs a high-sensitivity, fuzzy automatic tracking control system, producing gas on demand, generating gas when in use and not producing gas when not in use. It achieves automatic constant pressure and flow, ensuring that the pressure stability precision range is less than 0.001 Mpa, guaranteeing the instrument's output.GasHigh purity, stable pressure - safe, secure, and consistent.

Please use "qing."GasEquipment, pressure not exceeding

Instrument external air pathway connection leaks

Product QingNitrogenFlow rate value

Deviation is too great.

Electrolytic cell aging

2. Abnormal power output current

1. Replace electrolytic cells, clean electrolytic cells

2. Adjust power supply, replace power supply

qingAirImpure

Desiccant has expired

Replace desiccant

Water inside the purification and drying tube

The soda separator is unable to drain properly.

Replace air-water separator

Clean separator gas-water

Excessive pure water consumption

1. Leaking in the water recirculation pipeline

2. Electrolytic cell temperature too high

Observe and eliminate water leakage

Electrolytic cell aging - replace electrolytic cell or clean electrolytic cell
