Introduction — What Is a Nitrogen Generator? / 什麼是氮氣發生器？
EN:
A nitrogen generator is an on-site gas generation system that separates nitrogen from compressed air using either Pressure Swing Adsorption (PSA) or membrane technology. In Hong Kong’s industrial environment — where space, cost efficiency, and purity are critical — nitrogen generators provide a reliable and sustainable solution for continuous nitrogen supply without relying on bottled or liquid nitrogen deliveries.
粵語：
氮氣發生器（Nitrogen Generator） 係一種現場產氣系統，透過 變壓吸附（PSA） 或 膜分離技術（Membrane Technology），將壓縮空氣中嘅氮氣分離出嚟。喺香港咁嘅高密度工業環境之下，氮氣發生器可以提供穩定、安全同經濟嘅氮氣來源，唔需要再靠樽裝或液氮配送，大大節省成本同時間。
Technologies Used — PSA vs Membrane Systems / 技術對比：PSA同膜分離系統
EN:
- PSA Nitrogen Generator — uses carbon molecular sieves to adsorb oxygen, producing nitrogen with purity up to 99.999%, ideal for electronics, pharmaceuticals, and laser cutting.
- Membrane Nitrogen Generator — uses hollow-fiber membranes to separate gases; more compact, requires less maintenance, but purity typically ranges from 95% to 99.5%.
粵語：
- PSA制氮系統：利用碳分子篩吸附氧氣，產出純度可達 99.999% 嘅氮氣，特別適合電子、藥品、生物科技、鐳射切割等行業。
- 膜分離系統：利用中空纖維膜分離氣體，體積細、結構簡單、保養方便，但純度一般介乎 95%–99.5%，適合一般工業同食品包裝用途。
