Pump Up Calculator

Time to fill tank in minutes

Fill the form below

Input tank volume in gallons
Input final pressure in PSI
Input initial pressure in PSI
Input compressor flow rating in CFM
*Optional* Input atmospheric pressure
You can use the pump up calculator to check that your compressor is operating at it's rated flow. All you need to use the calculator is to time how long it takes for the pressure in your tank to go from one pressure to another and compare it to the value given in the calculator. Of course you will need to know the flow rating of your compressor to use the pump up time calculator effectively. If you do not know the flow rating of your compressor or you would like to calculate the flow of the compressor you can use the compressor flow calculator below.
Atmospheric pressure defaults to 14.7 PSI. If you know your atmospheric pressure you can enter it.

Compressed Air Flow Calculator

Flow into or out of a tank

Fill the form below

Input Tank volume in Gallons
Input final pressure in PSI
Input initial pressure in PSI
Input time in minutes
Input time in seconds
*Optional* Input atmospheric pressure
If you do not know the flow rating of your compressor or you would like to calculate a leak rate for your compressed air system then you can use this flow calculator. It is very similar to the pump up calculator. All you need to do is enter your tank size, initial pressure, final pressure, and the time it took and the calculator will do the rest.
Atmospheric pressure defaults to 14.7 PSI. If you know your atmospheric pressure you can enter it.

Cost to run an air compressor

Man these things are expensive

Fill the form below

Input Compressor Horsepower
Input hours over which you would like to calculate cost
Input compressor cost per KWH in dollars
*Optional* Input motor efficiency in whole number without %
This is what is most important to the manager of the plant or owner of the compressor. This will tell you how much it costs in electricity to run your air compressor. To use the calculator enter the compressor horsepower (KW/.746) don't forget to include the fan, the time over which you would like to calculate (one year at 24 X 7 is 8760 hours), cost of electricity in KWh (this can be found on your electric bill), and the efficiency of the motor (this is on the nameplate). This is an easy way to see how much changing your motor out for a higher efficiency motor can save you.
