High Purity Nitrogen and Dry Air Generators

High purity nitrogen and dry air generators produce on-site gas supply for analytical instruments, laboratory equipment, and industrial processes. These systems eliminate dependence on delivered gas cylinders and remove the cost and risk of cylinder storage, handling, and replacement in laboratory and production environments.

Two core separation technologies drive available systems. Pressure Swing Adsorption (PSA) uses dual towers packed with Carbon Molecular Sieve (CMS). Oxygen, CO₂, and other gases adsorb onto the CMS while nitrogen flows through. Towers alternate between adsorption and regeneration cycles controlled by solenoid valves and a PLC. Furthermore, inline oxygen analyzers continuously monitor output purity and divert off-spec gas before it reaches connected instruments. PSA systems reach purity levels up to 99.999% — suitable for gas chromatography (GC), mass spectrometry, differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA).

Membrane separation systems pass filtered, dried air through hollow fiber bundles. Oxygen, CO₂, and water vapor permeate the membrane walls faster than nitrogen. As a result, the nitrogen-rich core stream exits as product gas. This method requires less maintenance but caps purity at approximately 99.5% — adequate for laser cutting, electronics blanketing, and food packaging applications.

The Parker G6 and G7 combined units produce 99.999% nitrogen alongside dry air from a single plug-and-play unit with an integral oil-free compressor. Flow rates cover 0.6 to 3 L/min at a maximum outlet pressure of 72.5 PSI. Additionally, inlet pressure requirements across PSA systems typically run 100–150 PSI with dew point suppression to -40°F to protect CMS beds from moisture damage.

These systems serve Pakistan’s pharmaceutical QC laboratories, university analytical departments, hospital diagnostic instrument rooms, forensic science labs, and electronics manufacturers across Karachi, Lahore, and Islamabad requiring continuous on-demand high-purity gas without cylinder logistics.
