Sourcing a CE-certified oxygen regulator that holds flow accuracy under hospital pressures remains a challenge for procurement teams. The Mady-C3 Flow Meter with Oxygen Regulator from Guangzhou Maya Medical Equipment Co., Ltd. addresses this with a brass…
Product Description
Medical gas delivery demands predictable flow rates and pressure control, especially in oxygen therapy settings. The Mady-C3 Flow Meter with Oxygen Regulator is designed for oxygen gas, with a listed input pressure of 150 bar and an output pressure maintained between 2 bar and 3 bar. The unit uses a pressure-based theory and includes a safety valve set at 3.5 bar ± 0.5 bar, which helps prevent over-pressurization.
Built with a brass body, this flow meter offers a range of 1 liter per minute to 15 liters per minute, making it suitable for various clinical and emergency oxygen applications. The connecting thread is available in male or female G5/8, a common fitting in medical gas systems. The device weighs 18 kg and is packed in a carton or wooden box for transport.
In oxygen therapy, a stable output pressure is critical to ensure the patient receives the prescribed flow rate. The Mady-C3's output pressure of 2–3 bar means the device can compensate for fluctuations in cylinder pressure as the oxygen is consumed. The safety valve, set to release at 3.5 bar ± 0.5 bar, adds a layer of protection against regulator failure. Brass construction contributes to durability in repeated medical use, while the 1–15 L/min flow range covers both low-flow pediatric and higher adult emergency requirements.
This product is listed under the Health & Medicine category and is trademarked MAYA, with a CE specification. The manufacturer indicates a monthly production capacity of 10,000 pieces for this oxygen regulator model. The CE specification is listed by the manufacturer, which may help streamline importation into markets requiring CE-marked medical devices. However, buyers should request a copy of the certificate and verify its scope.

Practical benefits for procurement teams:
- Pressure stability: Output stays within a narrow 2–3 bar window, reducing flow fluctuation risks.
- CE marking: Listed specification indicates compliance with relevant EU directives.
- Brass construction: Durable, corrosion-resistant material suitable for medical gas environments.
- Wide flow range: 1–15 L/min covers low-flow adult and pediatric oxygen delivery.
- Standard fittings: G5/8 thread option in both male and female connection for flexibility.
These specifications are drawn directly from the supplier's product listing. Note that the safety valve pressure of 3.5 bar ± 0.5 bar provides an upper limit before venting, which is critical for preventing accidental oxygen over-pressurization in hospital pipelines.
Company Profile
Guangzhou Maya Medical Equipment Co., Ltd. is based in Guangdong, China, and operates as a medical equipment supplier. Its product portfolio spans a broad range of hospital and clinical categories, including X-ray machines, ultrasound scanners, hemodialysis machines, patient monitors, anesthesia machines, dental equipment, laboratory equipment, and hospital furniture.

The company also provides medical disposable materials, indicating a supply chain geared toward recurring consumable orders alongside capital equipment. The Mady-C3 Flow Meter with Oxygen Regulator fits within this catalog as a component for medical gas delivery systems. Buyers seeking a single vendor for multiple medical device categories may find this breadth useful, though verification of specific certifications and warranties is recommended directly with the supplier.
As a manufacturer of medical equipment, Guangzhou Maya Medical Equipment Co., Ltd. is positioned to support bulk orders for oxygen regulators, with a stated production capacity of 10,000 units per month. This capacity suggests readiness for mid-size hospital projects or distribution agreements. The company's listing also includes diagnostic imaging and life support equipment, suggesting capabilities in electro-mechanical and gas-related devices.
Export & Logistics
The listed production capacity for this oxygen regulator is 10,000 pieces per month, which supports mid-to-large volume procurement. Packing is specified as carton or wooden box, suitable for international shipping. The product originates from Guangdong, a major export hub in southern China with established logistics infrastructure.

For buyers planning container loads or mixed-pallet orders with other medical equipment, consulting the supplier about exact packaging dimensions, HS codes, and documentation requirements is advised. While CE marking is listed, importers should confirm the exact certification scope and any additional compliance needs for their destination market.

Because the device weighs 18 kg per unit, shipping costs will depend on order quantity and destination. Buyers should request packing details and incoterms from the supplier before finalizing logistics plans. The carton or wooden box packaging provides basic protection during transit, but additional crating may be required for fragile components if specified by the buyer. Common export practices for such goods include providing a commercial invoice, packing list, and certificate of origin. Because the product is CE-marked, a Declaration of Conformity may also be available on request. Buyers should clarify whether the wooden box packaging meets the destination country's phytosanitary requirements.
