AirSep AS-D+ PSA Oxygen Generator
AirSep AS-D+ PSA Oxygen Generator
The AirSep AS-D+ PSA Oxygen Generator provides a dependable, on-site oxygen supply for medical, veterinary, industrial, and environmental applications. Using Pressure Swing Adsorption (PSA) technology, it separates oxygen from compressed air to deliver consistent purity without relying on delivered cylinders or liquid oxygen. Ideal for hospitals, surgical centers, and veterinary facilities, the AS-D+ ensures cost-effective, self-sufficient oxygen generation with minimal maintenance.
Key Features and Benefits
- High Oxygen Output: Produces 80–100 SCFH (2.10–2.63 Nm³/hr) of oxygen at 93% ± 3% concentration.
- Reliable Performance: Generates oxygen from an independent compressed-air source using proven PSA technology.
- Microprocessor Controlled: Fully automatic, unattended operation with easy-to-read system indicators.
- Optional NEMA 4 Touchscreen: Integrated oxygen concentration monitor and digital control interface available.
- Energy Efficient: Low operating cost with minimal power draw and water-saving design.
- Durable Construction: Stainless steel and powder-coated components designed for long-term continuous use.
- Compact Footprint: Floor-mounted system with 27 × 22 × 69 in dimensions and a weight of 498 lb.
- Quiet Operation: Engineered for smooth, low-noise performance suitable for clinical environments.
- Easy Installation and Maintenance: Plug-and-play setup with accessible service panels and low-maintenance components.
- Optional Accessories: Available oxygen receiver tanks, hose kits, isolation valves, regulators, and cylinder backup manifolds for complete system integration.
