Dry Air Systems - Nitrogen Generator

Dry Air and Nitrogen Generator Systems are gas supply platforms that produce instrument-grade dry air or high-purity nitrogen on demand from compressed ambient air, eliminating the operational cost, logistics, and safety risks associated with bottled gas cylinder supply in laboratory, analytical, and industrial environments. By generating carrier and detector gases locally, these systems provide a continuous, uninterrupted gas supply independent of delivery schedules and cylinder inventory management.

Dry air generator systems remove moisture and hydrocarbon contaminants from compressed air through a sequential treatment train: a coalescing pre-filter removes liquid water and oil aerosols, a desiccant or membrane dryer stage reduces water vapor content to dewpoints between -40°C and -70°C, and a catalytic oxidizer or activated carbon stage eliminates residual hydrocarbon traces to below 0.1 parts per million. Output air meets the purity specifications required as carrier gas, zero air, or combustion air for gas chromatographs, flame ionization detectors (FID), and total organic carbon (TOC) analyzers.

Nitrogen generator systems use pressure swing adsorption (PSA) technology to separate nitrogen from compressed air across carbon molecular sieve beds, producing nitrogen at purities between 95 and 99.999 percent depending on flow rate and selected purity grade. Output flow rates range from 1 LPM for single GC detector supply up to several hundred LPM for multi-instrument laboratories or industrial blanketing and purging applications. PSA nitrogen generators require only a compressed air supply input, with no consumable gases or specialist handling.

Combination dry air and nitrogen generator units supply both gas types from a single instrument footprint, reducing bench space requirements in multi-instrument laboratory environments.

In Pakistan, dry air and nitrogen generator systems are installed in pharmaceutical quality control laboratories, petrochemical analytical departments, food safety testing facilities, university chemistry departments, and industrial process environments requiring on-site instrument gas supply.

Tactical Supply Pakistan supplies dry air and nitrogen generator systems for laboratory, analytical, and industrial gas procurement across Pakistan.
