Cost Of Compressed Air Per Cfm
Cost Of Compressed Air Per Cfm. Cost ($/year) = motor bhp x.746 x hours of operation (per year) x electric rate ($/kwh) / motor efficiency compressed air. At $0.06 per kwhr, the estimated cost of compressed air is $0.02 per 100 cfm ($0.0002 per cubic foot).
We use a simple formula for calculating compressed air cost. With this information, we can estimate the total cost to make compressed air as shown in equation 3: At $0.06 per kwhr, the estimated cost of compressed air is $0.02 per 100 cfm ($0.0002 per cubic foot).
Cost ($/year) = motor bhp x.746 x hours of operation (per year) x electric rate ($/kwh) / motor efficiency compressed air.
With this information, we can estimate the total cost to make compressed air as shown in equation 3: 25 hp air compressor that runs 10 hours a day 5 days a week for a year with a $.12 kwh electric. If you run multiple shifts, multiply that number by 2 or 3;
A 10 hp compressor delivering 35 cfm = $0.007/minute, $0.42/hour, $10.08/day, $302.40/month or $3,628.80/year.
Compressed air is not free. If your plant runs 24/7/365, multiply it by 4.2. Compressed air is one of the most expensive sources of energy in a plant.
Use this formula for electrical energy calculation:
At 10 cents per kwh, this would mean the cost of the compressed air would be about $1.70 to $2.20 per hour of operation for every 100 cfm of constant flow. The cost when your compressor is fully loaded: We use a simple formula for calculating compressed air cost.
To calculate the cost of compressed air, use the following formula:
Find steps for air compressor electrical energy and cfm calculations below. Many facilities will know the cost of their compressed air per cfm, but for those which don’t, a cost of ($0.25/1000 standard cubic feet) can be used. Compressed air generation can account for 30% or more of an industrial facility’s total electricity consumed.
How to figure the electrical engery cost of running your air compressor.
Compressed air cost $0.30 per 1000 standard cubic feet per minute (scfm) including investment and maintenance costs. But few know how much they pay for compressed air. 1040 hours per year x 3.7 kw x 16 cents per kwh = $ 615.68 per year.
