If your doctor has recommended home oxygen therapy, you will need to choose between two types of medical oxygen cylinders: the traditional B-Type cylinder and the newer aluminium oxygen cylinder. Both are medical-grade, but they suit different needs and lifestyles.
This guide by Ankur Oxygen Gas Agency — Delhi's trusted oxygen supplier since 1995 — breaks down the key differences so you can make the right choice for your patient.
At a Glance: B-Type vs Aluminium Oxygen Cylinder
Here is a quick comparison of the two most popular medical oxygen cylinders in India:
B-Type Cylinder
• Material: Steel
• Weight: approximately 17 kg (full)
• Oxygen capacity: approximately 7,000 litres
• Best for: stationary home use, long-duration therapy
• Portability: low — used with a trolley
• OXT Kit: not included, purchased separately
• Refillable: yes
Aluminium Oxygen Cylinder (4.6L or 10L)
• Material: Aluminium alloy
• Weight: 2.5 kg (4.6L) to 5 kg (10L) — significantly lighter
• Oxygen capacity: approximately 460–1000 litres depending on size
• Best for: travel, mobility, short-duration use, ambulance
• Portability: high — lightweight, easy to carry
• OXT Kit: included (regulator, flowmeter, mask)
• Refillable: yes
When to Choose a B-Type Oxygen Cylinder
The B-Type cylinder is the right choice when:
• Your patient needs continuous oxygen therapy at home for many hours per day
• The patient is mostly stationary — bed-ridden or sitting in one place
• You need longer duration between refills to reduce logistics
• You are looking for a lower upfront cost
B-Type cylinders are the workhorse of home oxygen therapy in India. Most families use them as their primary oxygen source at home.
When to Choose an Aluminium Oxygen Cylinder
An aluminium oxygen cylinder is the better choice when:
• The patient needs to travel — to hospital appointments, family visits, or outdoors
• You need a backup cylinder that is easy to handle and store
• The patient is on a lower flow rate and does not need continuous all-day therapy
• You want a complete ready-to-use kit without buying accessories separately
The complete OXT Kit that comes with our aluminium cylinders includes a regulator, flowmeter, and face mask — making it genuinely ready to use straight from the box.
💡 Ankur Oxygen tip: Many families buy one B-Type for home base use and one aluminium cylinder (4.6L or 10L) for travel and as a backup. This combination covers all situations.
Which is More Affordable — B-Type or Aluminium?
B-Type cylinders typically have a lower upfront purchase or rental cost. However, aluminium cylinders are more durable over the long term because they do not rust, and they come with a complete kit included. The total cost of ownership over several years can be comparable.

Are Both Types Available in Delhi?

Frequently Asked Questions
Can I use a B-Type cylinder regulator on an aluminium cylinder?
No. B-Type cylinders and aluminium cylinders use different valve and regulator fittings. Always use the accessories designed for your specific cylinder type. Our OXT Kits are matched to the aluminium cylinders we supply.
Which cylinder is safer for home use?
Both are safe when used correctly. Aluminium cylinders do not corrode, which can be an advantage in humid environments. Always ensure your cylinder is from an authorised supplier and has been filled at a licensed plant — whether B-Type or aluminium.
Do I need a prescription for either type?
Yes. Both B-Type and aluminium oxygen cylinders are medical oxygen and require a doctor's prescription in India under the Drugs and Cosmetics Act.
Conclusion
For long-duration, stationary home oxygen therapy, the B-Type cylinder is the practical and cost-effective choice. For portability, travel, and backup use, the aluminium oxygen cylinder — especially with a complete OXT Kit — is hard to beat.
