Valmig O-GEN Medical Oxygen Generator

On-site medical oxygen, generated on demand.

The Valmig O-GEN produces medical-grade oxygen right at your facility using Pressure Swing Adsorption (PSA), drawing from compressed air to deliver a continuous 93–96% oxygen supply with no reliance on cylinder deliveries. A Valmig Smart Cycle controller pairs with variable-speed air compressors to hold energy use near 0.7 kWh/m³, while a zirconia-oxide or paramagnetic analyzer with dew point, CO, and CO² sensors continuously verifies gas quality and cuts supply automatically on a purity failure. Built-in telemetry allows remote monitoring and preventive maintenance, and the modular design scales from 6 to 54.5 m³/h across seven standard models for hospitals of any size.

Features

Reliable Oxygen, Full Autonomy

  • PSA Technology

    Pressure Swing Adsorption generates oxygen from ambient air.

  • Smart Cycle Efficiency

    Variable-speed control holds energy use near 0.7 kWh/m³.

  • Continuous Gas Analysis

    O₂ analyzer with dew point, CO, and CO² sensors.

  • Remote Telemetry

    Monitor performance and service the plant from anywhere.

  • Purity Protection

    Automatic system isolates supply if purity drops below spec.

  • 304 Stainless Build

    SS piping and pneumatic valves rated for 1,000,000 cycles.

  • Flexible Assembly

    IP55 container, stack-mount skid, or in-room installation.

  • Touchscreen Control

    Valmig controller, 4.3″ touch screen, Ethernet Modbus.

How It Works

System Flowchart

The O-GEN draws compressed, purified air and separates oxygen on site — supplying it straight to the hospital pipeline, or filling cylinders through an optional booster and manifold.

  • Standard Supply

    Air compression and purification → compressed air tank → oxygen generation → oxygen tank → oxygen to the hospital pipeline.

    O-GEN standard supply flow: air compression and purification, compressed air tank, oxygen generation, oxygen tank, then oxygen to hospital

  • With Cylinder Filling

    The same supply chain, extended with an oxygen filling booster and cylinder filling manifold to fill backup and transport cylinders on site.

    O-GEN cylinder-filling flow: adds an oxygen filling booster and cylinder filling manifold after the oxygen tank

Standard Models

Seven standard O-GEN models at 93–96% O₂ purity, each paired with a recommended Valmig compressor. For higher flow rates, modular systems can be combined.

Installation

Assembly Styles

The O-GEN can be delivered in three assembly styles to suit your site and installation preference.

  • O-GEN oxygen generator assembled inside an IP55 container
    CTN – Container

    IP55 Container

    Assembled in a closed, IP55-certified container. Recommended when there is no dedicated location for the generator — it eases installation while protecting the equipment from the weather and reducing noise.

  • O-GEN oxygen generator on a modular stack-mount metal skid
    SM / SMC – Stack Mount

    Modular Skid

    Assembled on a modular metal base (SM), with an optional noise enclosure (SMC). Recommended when a room already exists and the ease of a plug-and-play install is preferred.

  • O-GEN oxygen generator components installed in a room
    RA – Room Assembly

    In-Room Install

    For facilities with a room designed for the generator. All components are pre-assembled at Valmig to ease installation; this type may require a specific design and the inclusion of exhaust systems.
