Safe and Efficient Use of Compressed Air
The inefficient use of compressed air for blowoff applications may create problems due to the energy costs, noise level and potential danger to personnel who are exposed to high pressure air. Open air pipes, copper tubes and drilled pipes are a few of the common abusers. They consume tremendous amounts of energy and often produce noise levels over 100 dBA.
Saving Money and Compressed Air
The table above shows the air consumption for typical homemade blowoffs.
Consider the following example where a Model 1102 Mini Super Air Nozzle replaces a 1/8" (3.2mm) open pipe. The compressed air savings is easy to calculate and proves to be dramatic. Payout for Air Nozzles and Jets, including filter and installation cost is measured in weeks - not years, as is the case for other cost reduction equipment. Based on a 40 hour work week, 52 weeks a year.
- Example: Existing blowoff is 1/8" (3.2mm) open pipe at 80 PSIG (5.5 BAR) supply. Air consumption, from the table above, is 70 SCFM (1,981 SLPM).
- Use a 1/8 FNPT Model 1102 Mini Super Air Nozzle also at 80 PSIG (5.5 BAR) supply. Air consumption is 10 SCFM (283 SLPM).
- Compressed air saved = 70 - 10 = 60 SCFM (1,981 - 283 = 1,698 SLPM).
- For this example, the blowoff is continuous. If the duty cycle was 20%, then air saved would be 60 x .2 = 12 SCFM (1,698 x .2 = 340 SLPM).
- Most large plants know their cost per 1,000 standard cubic feet of compressed air (10,000 standard liters). If you don't know your actual cost per 1,000 SCF, $0.25 is a reasonable average to use. (Cost per 10,000 standard liters is approximately $0.089.)
- Dollars saved per hour = SCFM saved x 60 minutes x cost/1,000 SCF (SLPM saved x 60 min x cost/10,000 SL) = 60 x 60 x $0.25/1,000 (= 1,698 x 60 x $0.089/10,000)
- = $0.90/hour
- = $0.90/hr. is $36.00/week and
- = $1,872.00/year savings, for One nozzle!
Stay Safe
If an air hose, open pipe, or copper tube has an outlet pressure that's greater than 30 PSIG, a worker can be seriously injured or killed if they block the opening with a hand or other body part. At that pressure, it is possible for air to enter the bloodstream through the skin (Occupational Safety and Health Administration (OSHA) standard CFR 1910.242(b)). Every one of EXAIR's Air Nozzles have been designed to prevent that blockage at any pressure. If you are currently using open pipe or commercial nozzles for your blowoff or cooling operation, you're already well aware of how loud it can get. These devices can produce noise levels that are well over 100 dBA. OSHA warns that an unprotected worker can only work for 2 hours in the proximity of 100 dBA noise before permanent hearing loss will occur (OSHA standard 29 CFR 1910.95(a)). For instance, EXAIR's Model 1100 Super Air Nozzle has a noise level of only 74 dBA at 80 PSIG yet still produces .8 lbs of strong blowoff force!
Save Money
One item that is often overlooked when auditing your company's expenditures is the cost of compressed air. On a 24 hour production line, reducing average compressed air use by even one Standard Cubic Foot per Minute (SCFM) can result in a savings of over $130 per year and, replacing open tubing or a commercial nozzle with an engineered nozzle from EXAIR can reduce air use by 50-70%!
