Invacare Oxygen Conserver Tanks Overview

Here is a summary of the features and specifications of 4 Invacare Oxygen Conserver Tanks.

Invacare M2 Conserver with Bag

The smallest conservation tank available for the Homefill system can hold up to 57 liters of oxygen! It delivers up to 2 LPM (liters per minute) of pulse dose oxygen, and is perfect for those who need only this amount, for up to 24 minutes at a time.

It also only takes 24 minutes to refill. That means you can fill it up, go outside and work in the garden, or take a trip to the store, and be back in time to refill it for a second dose. It's also the most lightweight, smallest and most unobtrusive of the Homefill conservation tanks, weighing just 2 lbs. It measures 3 inches in diameter and 8.25 inches tall. The bag it comes with makes it easy to strap it on while you're using it, and going about your day.

Invacare M4 Conserver with Bag

The second largest of the Homefill system's conservation tanks can hold up to 113 liters of oxygen, and will deliver 2 LPM of pulse dose oxygen for up to 55 minutes. This is perfect for those who need to use 2 LPM equivalent of pulse dose oxygen for a longer period of time, and if you need to be away from home longer and can't stop your oxygen therapy for up to 55 minutes. It will also take 55 minutes to refill this conservation tank.

The M4 conservation tank only weighs 3.1 lbs, so you will barely notice that it's there. It's size is 4.38 inches in diameter, and 9 inches high. This slightly larger conservation tank's carry bag has a different strap to compensate for the placement of size and weight to be carried comfortably on your body while you move around. You can wear it over one shoulder, or across your body from one shoulder to the other hip.

Invacare M6 Conserver with Bag

The M6 conservation tank, along with its bag, offer a considerable amount of freedom with its oxygen capacity and small size, even though its the third largest of the Homefill tanks. It holds up to 175 liters of oxygen. At a pulse dose equivalent of 2 LPM, just like the others, you'll be able to use it for as long as 75 minutes before needing a refill! The M6 conservation tank sits at 4.38 inches in diameter, and 11 inches tall.

It also takes 75 minutes to refill, since it's a slightly larger tank. Despite its oxygen capacity, it only weighs 3.5 lbs, only .3 lbs heavier than the M4 tank, which has a considerably smaller oxygen capacity. This is a great option for those who need to use 2 LPM equivalent of pulse dose oxygen for longer than one hour at a time. This might just meet your dosage need for the whole day!

The carry bag that comes with the M6 conservation tank is fit especially for the M6 Homefill tank, even though it looks the same as the M4 tank. This is because they are not that much different in size. The bag is designed for a tank that is 4.38 inches in diameter, just like the M4 tank, only 2 inches taller to make sure the whole tank is covered and secure.

Invacare M9 Conserver with Bag

The largest conservation tank compatible with the Homefill system, makes a big jump from the second smallest size. This is so it can be sure to cover the needs of oxygen patients who need to use it for longer than 75 minutes at a time. The M9 tank can hold a whopping 255 liters of oxygen, and can deliver 2 LPM equivalent.

It can be used for as along as 125 minutes before needing to be refilled – that's just a little over 2 hours of oxygen! Just like the others, it will take an equal amount of time to refill, which in this case, would be 125 minutes. It weighs 4.8 lbs and sits at 4.38 inches in diameter and 14 inches tall, so it's only 3 inches taller in size than the M6 tank. The carry bag is also similar, but is designed specifically to fit the M9 tank.
