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.

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.

What is the difference between continuous flow and pulse flow?
Pulse flow concentrators deliver the required oxygen only when you breathe in. While continuous-flow oxygen concentrators provide a constant flow of oxygen, regardless of whether you are inhaling.
Continuous flow is suitable for those who need a non-stop oxygen supply, while pulse flow is mainly used on portable oxygen machines for lower power consumption and longer battery life.
What is a nebulizer and nebulizer therapy?
VH-4 home oxygen concentrator has a nebulizer function. A nebulizer is a medical device used in respiratory therapy to deliver medication directly into the lungs in the form of a mist. It converts liquid medication into fine particles that can be easily inhaled by the patient. Nebulizer therapy involves using a nebulizer to administer medication for the treatment of respiratory conditions such as asthma, COPD, cystic fibrosis, and more. It is suitable for patients of all ages, and is highly effective in delivering medication directly to the lungs, providing quick relief and targeted treatment.
Can I use VH-4 overnight?
Yes. The high-quality compressor in Vh-4 allows for continuous use up to 72 hours. It operates quietly with a low noise level at 45 dB, so you can sleep soundly while using it over the night.
