Zero Air Generator 30lpm SKU: ZA-747-30

The ZA-747-30 Zero Air Generator delivers up to 30 LPM of ultra-pure air at 60 PSI, designed for labs that require consistent, contaminant-free gas for critical applications. Built for reliability and long-term performance, this system combines advanced purification technology with low maintenance and operating costs.

Two-Stage Purification Process

1. Pressure Swing Absorption (PSA): Dual chambers and a molecular sieve remove moisture and contaminants from incoming air.
2. Heated Catalytic Reactor: A high-temperature chamber with a precious metal catalyst eliminates methane (CH₄) and traces of hydrocarbons, converting them into trace CO₂ and water vapor.

Key Benefits

• Improved Detector Performance: Reduces hydrocarbons and methane to less than 0.005 ppm, lowering background noise and stabilizing baselines for more accurate results.
• Cost Efficiency: Requires only a power source and oil-free dry air, often paying for itself within 6 to 12 months compared to cylinder costs.
• Uninterrupted Operation: Provides a continuous, high-purity air supply, eliminating the downtime and risks associated with changing gas cylinders.
• Simple, Safe Design: Compact, rack-mountable or bench-top configuration with multiple fail-safes for dependable use.
• Expert Support: Designed and manufactured in Cleves, Ohio by Tisch Environmental, with over 40 years of experience in zero air technology.
• Comprehensive Warranty: Comes standard with a 3-year warranty, with an optional 2-year extension available.

The ZA-747-30 eliminates the need for gas cylinders, reducing handling risks and improving analytical consistency. It’s the dependable choice for laboratories that demand clean, stable zero air for sensitive instruments.
