5 L/min PSA oxygen concentrator that supplies anesthesia machines and ventilators and doubles as a nebulization source in the veterinary clinic.
Product Overview
The V-Y501W is a 5-litre oxygen concentrator that produces oxygen from room air by pressure swing adsorption (PSA) using an imported lithium molecular sieve. It delivers oxygen at 93% ± 3% with a maximum recommended flow of 5 L/min, removing the need for cylinder changes at the anesthesia station.
A 7 mm oxygen outlet connects to anesthesia machines and ventilators, while a second outlet drives nebulization, so one unit covers both oxygen supply and aerosol therapy. A large display with touch keys, voice prompts, infrared remote control, and timed shutdown keep operation fast in the prep room, surgery, and ward.
Key Features

Clinical Applications
- Oxygen supply for inhalation anesthesia machines in surgery and dental suites
- Oxygen source for veterinary ventilators
- Pre-oxygenation before induction and oxygen support during recovery
- Supplemental oxygen for canine and feline patients with respiratory compromise in the ward
- Nebulization therapy using the dedicated nebulizer outlet
Workflow & Installation Notes
- Connect the anesthesia machine or ventilator oxygen inlet hose to the 7 mm oxygen outlet
- Press the oxygen key to start production; set the required flow with the front knob and read it on the flowmeter
- Use the display to confirm oxygen concentration and to set timed shutdown; the remote control operates the unit from a distance
- For aerosol therapy, connect a nebulizer set to the nebulizer outlet
- Contraindications stated by the manufacturer: oxygen toxicity and oxygen allergy
- If stored below 5 °C, keep the unit at normal operating temperature for more than four hours before use
- Store in a well-ventilated room away from strong sunlight and corrosive gas; transport upright and avoid sharp shock

Why Choose the V-Y501W
- Workflow efficiency: continuous on-site oxygen removes cylinder changes and refill logistics at the anesthesia station
- Clinical accuracy: live oxygen concentration display with low-concentration alarm confirms delivered oxygen quality
- Practice economics: one unit covers anesthesia oxygen supply and nebulization, and eliminates recurring cylinder costs
Warranty & Support
Warranty terms for the main unit are confirmed at the time of order. Probes, cuffs, cables and other accessories follow standard wear-item terms.
Frequently Asked Questions
- Can the V-Y501W supply an anesthesia machine?
- Yes. It is designed for use with anesthesia machines and ventilators through its 7 mm oxygen outlet, with a maximum recommended flow of 5 L/min.
- What oxygen concentration does it deliver?
- 93% ± 3% within the recommended flow range. The manufacturer states 30%–90% when flow is set above 5 L/min.
- Can it be used for nebulization?
- Yes. A dedicated nebulizer outlet allows oxygen generation and nebulization from the same unit.
- What happens if the oxygen concentration drops or power fails?
- The unit raises a low oxygen concentration alarm and a power failure alarm. The compressor is protected against over-temperature and the unit shuts down on overcurrent or a loose connection.
- What power supply does it need?
- AC 220 V mains power.
