A D oxygen cylinder typically contains about 415 liters of oxygen. At a flow rate of 10 liters per minute, the cylinder would last approximately 41.5 minutes.

A full E cylinder typically holds 680 liters of oxygen. At a flow rate of 5 LPM, the E cylinder would last approximately 136 minutes (2 hours and 16 minutes).

A size E oxygen cylinder typically holds around 6800 liters of oxygen. At a flow rate of 4 liters per minute, the cylinder would last for approximately 1700 minutes, or about 28 hours.

An average d size tank will last for about 20 min with a non re breather at 15 lpm Duration = ((current pressure -200) x tank factor) / flow rate tank factors are M=1.56 E=0.28 D=0.16

If you are searching for oil lubricated pumps, which are available in fiber & steel vanes along with the capacity from 150LPM (Liters per minute) to 1200 LPM. There is only one company that can help you is Falcon Vacuum Pumps & System.

A size D oxygen cylinder typically contains around 418 liters of oxygen. At a flow rate of 2 liters per minute (LPM), the cylinder would last approximately 209 minutes or about 3.5 hours.

A size C oxygen tank typically holds around 1700 liters of oxygen. If you are using 2 liters per minute, the tank will last for approximately 850 minutes, or about 14 hours.

This will depend upon the gas flow rate. A size E oxygen cylinder in the UK contains 680 litres of compressed gas. At a flow of 10L/min for medical emergency use the cylinder will therefore last 68 mins. However if used at 6L/min it will last nearly 2 hours. In the US we use PSIG (gauge level). at full a tank is about 2200 PSI on any given tank size, and the E cylinder has a tank factor of 0.28. So you take take the PSI and multiple it by by the tank factor and divide that number by the flow rate. So at full, 2200 x 0.28 = 616 and dvided that by the flow rate. The final number is the total number of minutes at the given flow rate. So at 2 liters per minute (2 lpm) a completely full E cylinder will last 308 minutes or 5.13 hours (divide total minutes by 60 to get hours). 140 minutes at 4lpm, and so on. You deffinetly want to call your oxygen supplier well before the guage gets to the red. With most guages the very start of the red line (the end farthest from empty) is around 500 PSI. A good rule of thumb is to round down to the nearest whole hour when figuring duration. So when I've needed to I look at 5.16 hours and say 5 hours. If you do run out or are into the red already, call 911 (or your local emergency service), all ambulances carry oxygen and better to have them arrive and use their O2 than to call your oxygen service because ambulance should be able to get their faster. Remember, at the very beginning of red (500 PSIG) a E cylinder will only last 140 divided by flow rate...so 70 minutes at 2lpm, 35 minutes at 4lpm, etc. Dont risk it, when in red, call 911 first, then your oxygen supplies...that is as long as you dont have any other cylinders to use. common tank factors: H Cylinder factor is 3.14 D cylinder factor is 0.16 (typical portable oxygen size) * in the USA, all oxygen tanks, when completely full, are 2200 PSI, if you know the tank factor, you can easily compute the duration. Calculating liquid oxygen is a whole nother ball of wax....

To convert liters per minute (LPM) to nanoliters per minute (NLPM), you can use the following conversion factor: 1 LPM is equal to 1,000,000 NLPM. So, to convert LPM to NLPM, simply multiply the LPM value by 1,000,000.

The duration a size G oxygen cylinder will last can vary based on the flow rate of oxygen being used. On average, a size G cylinder can last for about 7-8 hours at a flow rate of 2 liters per minute. It is best to consult with a healthcare provider or oxygen supplier for more accurate information based on your specific oxygen needs.
