VARON VH-4 | Continuous Flow Home Oxygen Concentrator (1-9 settings)

Experience dependable oxygen support with the VARON VH-4, a versatile home oxygen concentrator designed for everyday comfort.

VH-4 delivers continuous oxygen flow with 9 adjustable settings, achieving up to 90% oxygen concentration at 1 L/min, and providing stable, efficient supplemental oxygen for daily use. 

Designed with flexibility in mind, VH-4 features dual therapy modes for oxygen and nebulizer use. The included nasal cannulas and nebulizer set allow you to switch between oxygen therapy and nebulizer treatment as needed (note: the two modes should be used separately. For nebulizer therapy, a flow rate of 1 L/min is recommended).

For enhanced comfort, VH-4 operates quietly at approximately 45 dB, supporting restful sleep and a peaceful home environment. The built-in negative ion function, replaceable filter, and dust cap help ensure cleaner oxygen delivery, while the humidifier bottle reduces dryness for more comfortable inhalation.

User-friendly design is at the heart of VH-4. You can control the unit using intuitive touch buttons or the included remote control. The large LED display clearly shows flow rate, oxygen concentration, timing, and accumulated runtime. A sturdy carrying handle and smooth-rolling casters make it easy to move the unit from room to room. The built-in timer allows you to set therapy sessions from 30 minutes to 4 hours, while the unit automatically shuts off after 12 hours if no timer is selected.

Choose the VARON VH-4 for a convenient daily oxygen solution, ideal for home use by seniors and individuals seeking reliable respiratory comfort.

--Regularly maintain the exterior of the oxygen concentrator and carefully wipe around the vents. To remove dirt, rub the surface lightly.
--Clean the nasal cannula at least once a week. If it is used daily, it is best to change the nasal cannula every two months. If you don't use it frequently, replace it every three to six months.
--The filter of the oxygen generator can remove dust, dirt, and pollen from the air. Cleaning the filter once a month can extend the service life of the unit.
