Introduction to Oxygen Cylinder Sizes and Capacities
Oxygen cylinders are portable or stationary containers designed to store compressed oxygen under high pressure. They serve critical functions in hospitals, emergency response teams, industrial applications, and even recreational activities such as scuba diving. Knowing the different sizes and capacities of these cylinders helps in selecting the right type for specific needs, estimating usage duration, and ensuring safety standards are met.
In many cases, organizations and safety protocols rely on detailed documentation, often in PDF format, that provides standardized information about oxygen cylinder sizes, capacities, dimensions, and pressure ratings. These PDFs serve as vital references for technicians, healthcare workers, and safety officers to ensure proper handling and compliance with regulations.

Common Types of Oxygen Cylinders
Oxygen cylinders are categorized based on their physical size, volume capacity, and pressure ratings. The most common types include:
High-Pressure Cylinders
- Designed to store oxygen at pressures typically ranging from 2,000 to 3,000 psi.
- Used in medical settings, industrial applications, and welding.
Low-Pressure Cylinders
- Contain oxygen at lower pressures, suitable for specific applications like portable oxygen concentrators.
Diverse Cylinder Sizes
- Ranging from small, portable cylinders to large industrial tanks.

| B | 1.4 L | 250 L | Emergency oxygen | Slightly larger |
| C | 3.1 L | 340 L | Hospital portable use | Hand-held size |
| D | 4.4 L | 425 L | Ambulance, portable | Compact, portable |
| E | 6.1 L | 680 L | Hospital, homecare | Medium size |
| M (or H) | 10.2 L | 1500 L | Long-term hospital use | Larger, stationary |
Note: Capacities are approximate and can vary based on manufacturer specifications.
Industrial and Large-Scale Cylinders
| Size | Common Label | Capacity | Usage | Dimensions |
|--------|----------------|-----------|--------|------------|
| K | 47.6 L | 6,900 L | Industrial welding, manufacturing | Large, stationary |
| L | 16.4 L | 2,200 L | Industrial processes | Larger, stationary |
| P | 113.6 L | 17,000 L | Industrial applications | Very large |

Understanding Cylinder Capacity and Volume
The capacity of an oxygen cylinder is typically expressed in liters (L) and indicates the volume of oxygen it can store at a specified pressure. However, the actual usable oxygen depends on the pressure at which the cylinder is filled and the pressure required for usage.
Key Factors Affecting Capacity
- Pressure Rating: The maximum pressure the cylinder can withstand.
- Working Pressure: The pressure at which oxygen is dispensed.
- Cylinder Size: Larger cylinders generally hold more oxygen.
- Regulator Settings: The flow rate and pressure settings influence how long the oxygen lasts.
Calculating Duration of Oxygen Supply
To estimate how long an oxygen cylinder will last, use the formula:
Duration (minutes) = (Cylinder Capacity in Liters × Pressure) / Flow Rate (L/min)
For example, a D-size cylinder with a capacity of 425 liters at 2000 psi and a flow rate of 2 L/min:
Duration ≈ (425 × 2000) / (2 × 1000)
≈ (850,000) / 2000
≈ 425 minutes

How to Choose the Right Oxygen Cylinder Size
Selecting appropriate cylinder sizes depends on several factors:
- Application: Medical, industrial, recreational, or emergency.
- Duration of Use: Short-term or long-term.
- Mobility Needs: Portable vs. stationary.
- Flow Rate Requirements: High flow or low flow.
Guidelines for Selection
1. Assess the oxygen demand based on the number of patients or applications.
2. Estimate the duration oxygen needs to determine the minimum cylinder capacity.
3. Consider mobility—smaller cylinders for portability, larger ones for extended use.
4. Consult technical specifications and PDFs to verify capacities and dimensions.
5. Ensure compliance with safety regulations and standards.

Frequently Asked Questions
What are the common sizes of oxygen cylinders available in medical settings?
Common oxygen cylinder sizes include E (small portable), M, H, and K cylinders, each varying in capacity from approximately 400 liters (E) size to over 6000 liters (K size), providing options for portability and longer supply depending on medical needs.
How can I determine the capacity of an oxygen cylinder from its specifications?
The capacity is typically listed on the cylinder's datasheet or PDF documentation, indicating the volume in liters (e.g., 680L, 1500L). It can also be calculated based on the cylinder's pressure and volume, with standard formulas provided in oxygen cylinder size charts.
Why is it important to understand oxygen cylinder sizes and capacities in healthcare?
Understanding sizes and capacities ensures proper supply management, safety during transportation and storage, and accurate oxygen delivery to patients, preventing shortages or overflows during medical emergencies.
Where can I find detailed PDFs or charts about oxygen cylinder sizes and capacities?
