Source-backed oil-free and process-gas compressor references for B2B review. Oxygen-service suitability is confirmed from your purity, pressure, flow, materials, cleanliness and safety requirements — never inferred from an air-compressor photo.
Every public entry carries an evidence level and media policy.

Review RFQ details →The site is designed to make the RFQ more precise without turning general compressor evidence into an oxygen approval.
Purity/composition, pressure, flow and temperature are the first matching inputs.
CM_B, CM_G, CM_GPV, CMW and CMT boundaries remain tied to Drive evidence.
Source photos and diagrams are labeled by match class rather than presented as exact O2 models.
Materials, cleanliness, seals, lubrication/isolation and safety basis require project review.
The approved material documents oil-free screw, medium-pressure and process-gas compressor architectures. Oxygen-specific gas-contact and safety design remains separate.
Source technical reference only — not an oxygen-service P&ID.
Choose the engineering path that matches what you already know about the project.
Define gas, pressure, flow, cleanliness and controls from the project specification.
Use the documented 20-40 bar air-compressor families only as platform references until oxygen suitability is approved.
Start from composition and contaminants; never transfer compatibility from a different documented gas.
Provide old model/part data, photos, P&ID and current operating conditions for independent engineering matching.
The catalogue keeps unsupported engineering values out of public model cards.
Suction, discharge, normal/min/max flow and duty profile.
Purity/composition, materials, seals, cleanliness and isolation requirements.
Cooling water, electrical supply, ambient/site conditions and package footprint constraints.
Fixed/variable-frequency logic, local/remote control, interlocks and plant interface.
Only the family-level facts directly supported by the source are published.
| Catalogue family / solution | Source-backed public boundary | O2-specific status |
|---|---|---|
| CM_G / CM_GPV | 20-40 bar oil-free screw air-compressor families; fixed vs variable frequency distinction | Oxygen suitability, exact model and flow are RFQ-confirmed |
| CM_B | Fixed-speed oil-free screw air-compressor family | Oxygen suitability and project configuration are RFQ-confirmed |
| CMW | Oil-free scroll air-compressor family | Oxygen suitability and operating envelope are RFQ-confirmed |
| CMT process-gas platform | Special-requirement/process-gas screw compressor; source lists several non-oxygen gases | Oxygen not listed; compatibility is RFQ-only |
| O2 engineering entries | RFQ solution pages only | All oxygen-service technical fields require engineering review |
Keep the decision trail auditable from gas data to approved configuration.
Purity/composition and contaminants.
Suction/discharge pressure, flow, temperature and duty.
Materials, seals, cleanliness and isolation policy.
Match only to a source family whose evidence scope is understood.
Confirm package, controls and project safety basis before order.
The approved Drive material is used to establish product families and visual evidence, while O2-specific suitability remains a separate engineering decision.
Send the exact project specification, P&ID, old model data or drawings when available. We will not use a brand name, photo or 20-40 bar label as automatic proof of oxygen compatibility.
Request engineering reviewA practical B2B path for source-controlled compressor RFQs.
Gas, pressure, flow, purity and site utility checklist.
Confirm whether the requested claim exists at family, model or RFQ-only level.
Use customer specifications, drawings and P&IDs to define the required package.
Keep the approved duty and configuration available for future service review.
