Oxygen concentrator is a device that provides oxygen therapy to patients at substantially higher concentrations than that of ambient air and keeps the level of oxygen in their blood stable. It is a medical equipment which compresses the air around the patient to deliver it to him/her in a purer form. The supply of oxygen is continuous and unlike an oxygen tank, can never run out as long as the battery is powered or the compressor plugged into an electrical outlet. We have a wide range of top grade stationary and portable O2 concentrators from experienced manufacturers. These devices, also referred to as oxygen generators or oxygen machines, provide a continuous stream of oxygen-enriched air and offer a cost-effective and most preferred at-home or on-the-go treatment.

Portable Oxygen Concentrators – Why choose them?

1. Battery Packs for Portable Oxygen Solution

Portable O2 concentrator uses battery packs and allows the oxygen user to stay mobile. It is small in size and lightweight, and can be carried around easily. Since the portable oxygen machine runs on a battery, a fully-charged battery will keep the machine operable outdoors unlike a stationary unit.

2. Multiple Power Options for convenient use of Portable Concentrator

Apart from portability, an extra benefit is that this type of portable breathing machine also runs on AC and DC current. It can be plugged into an electrical outlet if at home and if in the car, it can be charged through a DC power cord thus preserving the battery for outdoor use. Multiple power options of AC and DC current and rechargeable battery make it a convenient machine to have at home and outdoors.

3. Varied Usage Options for POC

Portable variety includes pulse dose oxygen concentrators which are smaller in size. Some portable oxygen units provide continuous flow of oxygen but these are larger in size and have built-on wheels. The portable variety has more options in terms of usage – portable type with high flow settings and personal oxygen concentrators less than 5 pounds.


The Inogen One G5 Portable Oxygen Concentrator is designed for 24 x 7 use and conforms to all applicable FAA requirements for POC use on board an aircraft. The Devilbiss iGo2 Portable Oxygen Concentrator System is designed with revolutionary SmartDose Technology that adjusts oxygen delivery in real time to fulfill patient requirements. Precision Medical EasyPulse Portable Oxygen Concentrator comes with 5 pulse dose settings and EasyPulse POC3 Portable Oxygen Concentrator comes with 3 pulse dose settings.

Stationary Oxygen Concentrators – Why choose them?

Stationary oxygen concentrator system provides a continuous flow of oxygen. It can be used 24x7 because to start functioning, it just needs to be plugged into a wall socket. The outflow of oxygen is higher (liter-per-minute) than the portable variety type and it can be wheeled around the house.

How does an Oxygen Concentrator work?

An oxygen concentrator takes in the regular air in the room and compresses it using filters and sieve beds to filter out the other gases present, including nitrogen. Concentrated and medical grade oxygen is delivered to the user via a mask or nasal cannula. An O2 machine delivers oxygen either as a continuous flow or in pulse doses.

1. Continuous Flow Delivery

If delivery is required constantly and at all times, then a continuous flow oxygen concentrator is necessary. The Inogen At Home Portable Unit for Oxygen Therapy provides continuous flow up to 5 liters per minute.

2. Pulse Dose Delivery

Pulse dose oxygen concentrator delivers oxygen in doses or bursts, every time you inhale. It is based on the breathing rate and the amount of oxygen taken in. This ensures delivery of an appropriate amount of oxygen based on different activity periods – sleep, rest or daily tasks. For more sophisticated and efficient solution, pulse dose works better. The Oxlife Independence Portable Oxygen Concentrator is versatile in nature and delivers oxygen in both continuous flow and pulse dose mode.


The selection of an oxygen concentrator will depend on your lifestyle as well – active or at home. Additional considerations include weight, size, power options and battery life. If you are looking for a quieter oxygen machine, then the size will be bigger. Smaller the size, the noisier it is.

What to use with Oxygen Machines?

  • Oxygen Cannula & Mask Oxygen cannulas and masks are used with oxygen machines to deliver oxygen to the user.
  • Humidifier BottleHumidifier bottles are used to provide humidity to solve the problems of sore, dry, or bloody nose.
  • Oxygen CompressorOxygen compressors are used to fill compressed oxygen from concentrator to Home Fill cylinders.
  • Home Fill Cylinders Oxygen cylinders help the user carry supplemental while on-the-go. They can be refilled by an oxygen concentrator.
  • Carry Bags Carry bags or backpacks are used to carry oxygen machines from one place to the other.
