Short answer: A PSA (pressure swing adsorption) nitrogen generator passes clean, dry compressed air through a bed of carbon molecular sieve, which holds back oxygen and lets nitrogen through. Two beds … read more

Short answer: Adsorption is when molecules of a gas or liquid collect on the surface of a solid, including the walls of its pores. Absorption is when a substance is taken into the whole volume of anot … read more

Short answer: Bottled nitrogen in high-pressure cylinders or manifold packs suits low, irregular or mobile demand, where a generator would take too long to pay back. Bulk liquid suits high, continuous … read more

Short answer: A PSA nitrogen generator separates nitrogen with beds of carbon molecular sieve (CMS), and oil, water and dirt in the feed air can damage that sieve for good. A pre-treatment train of wa … read more

Short answer: AS/NZS 1715 is the Australian and New Zealand standard for selecting, using and maintaining respiratory protective equipment (RPE). For compressed breathing air, it sets the air quality … read more
