How to calculate required air pressure in a factory.
by S Dekaraja
Air compressor air calculation for a factory is required what type of data? Bill answers... Nice to hear from India, Mr. Dekaraja. A lot of good questions asked here, and I'm pleased to say, they are already answered on pages within this site. If you are trying to figure out how much air a factory will use, in order to purchase the appropriate air compressor, that task is a bit time consuming. Here is information on compressor sizing. With reference to how much air a compressed air cylinder will use here's info on cylinder air consumption. There's no shortcut in the process, unless your compressor vendor will come in and do a site assessment for you, with the expectation that you'll be buying an air compressor from him or her. You have to think about all of the compressed air tools you might have, all of the air-driven equipment you might need, determine if all of what part of it will be operating when, and take that into account when determining the compressor size. While it's unfortunate, but also a reality, when you are estimating compressed air consumption in your plant, allow 5-10% for wastage and air leaks too. As to the compressor receiver or air tank, the rule of thumb for receivers is that they should have 1 gallon of capacity for every CFM of compressor output. Therefore, since a 25 HP compressor can theoretically generate about 100 CFM at 90 PSI, the receiver for that compressor should be 100 gallons in size. Here's information on compressed air receivers / tanks. I hope this helps. Cheers, Bill
