1-7L/min Home Oxygen Concentrator ZY-1J

1. Two Therapies, One Simple Solution
Use your VARON concentrator for both oxygen therapy and breathing treatments (nebulizer).
Pro Tip: Simply switch to the lowest oxygen flow when using your nebulizer.
Enjoy whisper-quiet operation (quieter than a refrigerator!) so you can rest peacefully without disturbing family or caregivers. The built-in rolling handle lets you move it effortlessly from bedroom to living room.

2. 1-7 L/min Continuous Oxygen Flow
Tailor your oxygen intake with 1-7 L/min adjustable oxygen flow. The oxygen concentration reaches up to 90% at 1 L/min flow. The filter filters air impurities, and the negative ion function ensures clean oxygen. In addition, the humidification bottle improves breathing comfort by humidifying the oxygen.

3. Smart Timer for Worry-Free Use
Choose 0.5-4 hour sessions or continuous flow (with auto-shutoff after 24 hours to protect the machine). Perfect for:
✓ Nighttime oxygen therapy
✓ Afternoon breathing treatments
✓ Preserving machine lifespan

4. Designed for Effortless Control
① Large, intuitive buttons with tactile feedback
② Handheld remote (no smartphone required!)

1. What is the difference between continuous flow and pulsed flow?

Pulse flow concentrators deliver oxygen only when you breathe in, saving power and extending battery life. On the other hand, continuous-flow concentrators provide a steady stream of oxygen, regardless of whether you're breathing in or not. Continuous flow is best suited for individuals who require a constant supply of oxygen, while pulse flow is ideal for portable units due to its lower energy consumption, which helps the battery last longer.

2. What is a nebulizer and nebulizer therapy?

The ZY-1J home oxygen concentrator comes with a nebulizer function. A nebulizer is a device used in breathing therapy to turn liquid medicine into a mist, which you can then inhale directly into your lungs. This therapy is often used to treat conditions like asthma, COPD, cystic fibrosis, and others. It’s suitable for all ages and works by delivering medicine straight to your lungs for faster relief and better treatment.

3. Can I use ZY-1J overnight?

The ZY-1J has a high-quality compressor that lets you use it continuously for 24 hours. It runs quietly, with a noise level as low as 42 dB, so you can rest easy without any disturbance, even if you're using it overnight.
