How Exair Air Nozzles Save Money and Compressed Air ?

Industrial air nozzles are widely used in India across various industries for applications such as cooling, drying, blowing off debris, and cleaning. But it is really complicated to find out a proper nozzle based on quality and cost.

Now I am going to explain you how you can save Money and Compressed Air if you select EXAIR Engineered Air Nozzles in India.

One of the worst culprits for inefficient air use is open pipe blow-offs. This would include cheap air guns, drilled holes in pipes, and tubes. These are very inefficient for compressed air and can cost you a lot of money.  I will share a comparison to a 1/8” NPT pipe to an EXAIR Mini Super Air Nozzle.  (Reference below).  As you can see, by just adding the EXAIR nozzle to the end of the pipe, the company was able to save per year.  That is some real savings.

The table above shows the air consumption for typical homemade blow offs. The pages that follow give the air consumption and other data on EXAIR's Air Nozzles and Jets. Consider the following example where a Model 1102 Mini Super Air Nozzle replaces an 1/8" 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: 

1. Existing blowoff is 1/8" open pipe at 80 PSIG (5.5 BAR) supply. 

Air consumption, from the table above, is 70 SCFM (1,981 SLPM). 

2. Use a 1/8 FNPT Model 1102 Mini Super Air Nozzle also at 80 PSIG (5.5 BAR) supply. Air consumption, from the image below, is 10 SCFM (283 SLPM). 

3. Compressed air saved = 70 - 10 = 60 SCFM (1,981 - 283 =1,698 SLPM) 

4. For this example, the blow off is continuous. If the duty cycle was 20%, then air saved would be 60 x .2 = 12 SCFM (1,698 x .2 = 340 SLPM).

 5. 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, Rs 29 is a reasonable average to use. 

(Cost per 10,000 standard liters is approximately Rs 10 )

 6. Money 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 Rs 29 /1,000 

                                         (= 1,698 x 60 x Rs 10 /10,000)

                                             =Rs 104/hour that is =Rs 4160/week and Rs 216,320/year savings for one nozzle.

Now please Let me answer and explain  to a very common question, we are asked during presentation of Exair's Air Nozzles that Why Exair Air nozzles consume less compressed air. 

Well, we will discuss the working principle of Exair Air Nozzles and which is of course the realistic answer.

Air Nozzles use the Coanda effect to amplify compressed airflow up to 25 times or more. As illustrated on top, compressed air (black arrows) is ejected through a series of nozzles on the outer perimeter. As the air travels along the outer wall of the nozzle, surrounding air (blue arrows) is entrained into the stream. The airstream that results is a high volume, high velocity blast of air at minimal consumption. The air is always ejected so it can vent safely, well below OSHA dead end pressure requirements, should the nozzle end be blocked.
