High Purity Nitrogen Generators for Beer Dispensing

Beer dispensing typically requires nitrogen purity between 99.5% and 99.999% to prevent oxidation and contamination of the beverage. Gardner Denver's PSA nitrogen generators can achieve purity up to 99.999%, ensuring the gas meets food-grade standards for draft beer systems and protecting product quality throughout dispensing.

Membrane generators are compact, low-maintenance units suited for lower flow rates (1–153 CFM) and moderate purity needs (95–99.5%). PSA (Pressure Swing Adsorption) generators provide higher purity up to 99.999% and greater capacity (15–2,353 CFM), making PSA the preferred choice when ultra-high purity is critical for sensitive beer dispensing applications.

Flow requirements depend on the number of taps, keg turnover, and line length. Gardner Denver's GDN2 and XGN2 Series cover capacities from 1 to 2,353 CFM, accommodating small craft breweries to large commercial operations. Comp-Air Ohio's specialists can assess your specific dispensing setup and recommend the correct generator model and capacity.

Yes. Gardner Denver nitrogen generators are designed to comply with strict industry standards including ISO 8573-1 air quality standards. The systems are built to deliver contaminant-free, high-purity nitrogen suitable for direct food and beverage contact applications, including draft beer dispensing, packaging, and preservation in commercial and brewing environments.

Absolutely. The XGN2 and GDN2 Series feature modular, skid-mounted designs that allow for flexible installation and scalability. As your draft beer operation expands - adding taps, kegs, or locations - additional generator capacity can be integrated without major infrastructure changes, protecting your initial investment and supporting long-term growth.

Gardner Denver nitrogen generators are engineered for long-term reliability with minimal maintenance. Comp-Air Ohio offers tailored Maintenance Service Plans, in-house and field service, and 24/7 emergency support for contract customers. Routine maintenance typically involves filter element replacement and periodic system checks, all supported by factory-trained technicians using genuine OEM parts.

Gardner Denver XGN2 and GDN2 Series nitrogen generators and Generon nitrogen generators are both available for draft beer and beverage dispensing, with filtration supplies and aftermarket parts carried alongside them.
