Oxygen Concentrators vs Oxygen Tanks: Understanding the Key Differences

For individuals suffering from respiratory conditions like COPD, emphysema, or sleep apnea, supplemental oxygen therapy can be a life-changing treatment. It increases the amount of oxygen in your bloodstream, alleviating symptoms like shortness of breath, fatigue, and cognitive decline. But when it comes to delivering this vital gas, two primary options emerge: oxygen concentrator and oxygen tank. VARON-UK, your trusted provider of Varon Oxygen Concentrator, dives deep into the differences between these two methods to help you make an informed decision.

In-Depth Comparison: Oxygen Tank vs. Oxygen Concentrator

A. Oxygen Tank

  • Size & Weight: Variable, typically bulky and heavy (10-60 kg).
  • Mobility & Portability: Mobile with carts, not portable for travel (FAA restrictions).
  • Safety: Risk of pure oxygen leaks.
  • How it Works: Stores and delivers pure oxygen at specific doses, regulated by a pressure gauge and flowmeter.
  • Pros: No power source needed, quieter operation, lower upfront cost.
  • Cons: Heavy and difficult to transport, expensive in the long run due to refills.

B. Oxygen Concentrator

  • Size & Weight: Variable, stationary models heavier (15 kg), portable models lighter (1-3 kg).
  • Mobility & Portability: Stationary models less mobile, portable models designed for travel (FAA approved).
  • Safety: No pure oxygen leaks, as it filters surrounding air.
  • How it Works: Uses Pressure Swing Adsorption (PSA) technology to separate oxygen molecules from nitrogen in the air, delivering medical-grade concentrated oxygen.

Detailed Explanation of Pressure Swing Adsorption (PSA):

PSA technology utilizes zeolite beds, a mineral with a high affinity for nitrogen. Air is passed through these beds; the zeolite traps nitrogen molecules, allowing concentrated oxygen to flow through the system and be delivered to the patient. This process is cyclical, with beds regenerating for continuous oxygen production.

Additional Considerations for Oxygen Concentrator


  • Portability: Varon Oxygen Concentrator offers unmatched portability for active lifestyles and travel.
  • Versatility: These concentrators are suitable for various oxygen therapy needs, from home use to exercise regimens.
  • WHO Support: The World Health Organization (WHO) recommends oxygen concentrator for COVID-19 patients requiring supplemental oxygen therapy.


  • Noise: Some models may generate operational noise.
  • Reliance on Power Source: Stationary models require a constant power supply, while portable models rely on batteries.

Additional Considerations for Oxygen Tanks

Benefits of Oxygen Tanks:

  • Immediate Availability: Oxygen tanks are pre-filled with compressed oxygen, eliminating the wait time associated with setting up a concentrator. This instant access to oxygen can be lifesaving in emergency situations.
  • Power Source Independence: Unlike concentrators which require electricity, oxygen tanks operate independently of a power source. This makes them ideal for situations where power outages are a concern or for outdoor activities like camping or hiking.

Drawbacks of Oxygen Tanks:

  • Limited Mobility: Oxygen tanks themselves can be bulky and heavy, ranging from 10-60 kg. While carts are available for easier transport, they're not ideal for extended use or travel.
  • Refill Costs: While the initial cost of an oxygen tank is lower, refills can become expensive over time. The frequency of refills depends on your prescribed oxygen flow rate.
  • Safety Concerns: Oxygen tanks store pure oxygen, which poses a fire hazard if mishandled. It's crucial to follow safety guidelines for storage, use, and transportation of oxygen tanks.
  • Limited Oxygen Supply: Oxygen tanks have a finite amount of oxygen, requiring regular monitoring and refills to avoid interruptions in therapy.

Choosing Between Oxygen Concentrator vs Oxygen Tank

Selecting the right oxygen delivery system depends on your specific needs and lifestyle. Here are some key factors to consider:

  • Purpose: What activities do you require oxygen for? For stationary use at home, either option might be suitable. Portable oxygen concentrators are ideal for maintaining active lifestyles and travel.
  • Size & Weight: Oxygen tanks can be bulky and heavy (ranging from 10-60 kg), making them difficult to transport. Varon Oxygen Concentrators come in both stationary and portable models, with portables designed for easy travel.
  • Mobility & Portability: Stationary oxygen concentrator requires a power source and are less mobile. Portable oxygen concentrators are designed for on-the-go use and outdoor activities. Oxygen tanks, while mobile with carts, are not portable as oxygen concentrator because of its weight and size.
  • Cost: Oxygen tanks have a lower upfront cost, but refills can be expensive over time. Varon Oxygen Concentrator requires a higher upfront investment but eliminate refill costs, making them a better long-term value.
  • Safety: Oxygen tanks pose a risk of leaks, as they store pure oxygen. Varon Oxygen Concentrator filters the surrounding air, eliminating the risk of pure oxygen leaks.

The best choice for you depends on your specific needs and lifestyle. Here's a quick comparison to help you decide:

Feature Oxygen Tank Oxygen Concentrator
Portability Limited (bulky, requires cart) Excellent (portable models available)
Power Source Independent Requires electricity (stationary) or batteries (portable)
Oxygen Supply Finite, requires refills Continuous, no refills needed
Safety Considerations Risk of fire if mishandled

No risk of pure oxygen leaks
