Description
The Comweld Series-O Air Regulator is the medical air variant of the Series-O premium clinical regulator. Same Encapsulated Seat Technology, large-diameter diaphragm, triple-filter system, and tamper-resistant safety design as the oxygen variant — with calibration and a gas-specific inlet for medical air supply. Suited to clinical environments running blended-gas therapy, ventilator support, or any setup requiring clinical-grade medical air regulation.
Key Features
- Encapsulated Seat Technology (EST) — surge resistance and accuracy.
- Large-diameter diaphragm — double-stage-equivalent performance.
- Triple-filter system.
- Tool-free routine disconnection.
- Built-in safety relief valve.
- Tamper-resistant design.
- Colour-coded gauges and labels.
- Medical-air-specific inlet.

Why this costs more than the oxygen variant
The Series-O Air is priced higher than the Series-O Oxygen (AU$560 vs AU$396). This reflects lower production volumes for medical air regulators (most clinical setups use predominantly oxygen). The components and engineering are equivalent quality. For sites running both oxygen and air regulators, the price difference is unavoidable — pair the right regulator with the right gas regardless.
Frequently Asked Questions
Series-O Air vs Series-O Oxygen — what's actually different?
Internally, the engineering is similar. Differences: gas-specific inlet (different connection geometry to prevent cross-connection), calibration (oxygen and air have slightly different gas densities affecting flow indication), and labelling (colour-coded for the correct gas).
Can I cross-use?
No — never. The gas-specific inlet design prevents cross-use, and using the wrong regulator on the wrong gas can damage the regulator and cause patient harm.
Where is medical air actually used?
Blended-gas respiratory therapy (mixing oxygen and air at controlled ratios), ventilator support requiring controlled gas mix, and some specialty therapies. Most home and basic clinical setups use oxygen only.
