Air Nozzles and Jets
Engineered Air Nozzles and Jets reduce noise levels and air cost!
"Go Green" by upgrading your Blowoff, Cooling and Drying operation to the award winning Super Air Nozzles!
EXAIR's Air Nozzles and Jets produce outlet flows up to 25 times compressed air consumption using a small amount of compressed air as the power source.
What are Air Nozzles and Jets?
A simple solution to reduce excessive air consumption and noise levels on compressed air blowoff operation. EXAIR Air Nozzles and Jets produce outlet flows up to 25 times compressed air consumption using a small amount of compressed air as the poser source.
Why Air Nozzles and Jets?
Air saving compared to open copper tubes or pipes commonly used for blowoff, can be as high as 80%. Less compressed air means less noise. The typical noise level reduction is 10 dBA. All EXAIR Air Nozzles and Jets meet Occupational Safety and Health Administration (OSHA) maximum dead end pressure and sound level exposure requirements and carry the CE mark.
An open 1/4" (6mm) copper tube, by contrast, ejects pure compressed air at up to 40 SCFM (1,133 SLPM), the entire output of a 10 HP compressor. Annual energy cost can be exced $1,000 per year. Noise levels is excess of 100 dBA are commonly produced. When supply pressure exceeds 30 PSIG (2 BAR), an open pipe, tube or drilled holes violates OSHA static pressure requirements.

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.
Open Air Pipe or Copper Tube
Turbulent compressed air blasts straight out of the pipe or tube. It not only wastes huge amounts of compressed air but also violaes OSHA noise and dead end pressure requirements.
Reduce Energy Costs
The best way to cut energy costs is through proper maintenance and use of the compressed air system. Leaks and dirty filters require maintenance on a regular basis. Energy savings can also be realized when replacing outdated compressor motors and controls with high efficiency models that often pay for themselves in a short period of time.
The most important factor to dramatically boost efficiency is proper use. Using engineered products like EXAIR's Super Air Nozzles can cut operating costs since they use only a fraction of the compressed air of typical blowoffs. In addition, all of EXAIR's Air Nozzles and Jets can be cycled on and off with an instantaneous response. EXAIR's EFC is an electronic flow control that limits compressed air use by turning on the air only when a part is present.
Reduce Noise Levels
High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA noise level exposure requirements, resulting in hearing loss to those working in close proximity. Noisy blowoffs at 80 PSIG (5.5 BAR) that produce noise levels of 100 dBA can be reduced to only 74 dBA when using a Super Air Nozzle. At that pressure, it is still possible to obtain hard-hitting force without the high noise.
Eliminate Harmful Dead End Pressures
Air can be dangerous when the outlet pressure of a hole, hose or copper tube is higher than 30 PSIG (2 BAR). In the event the opening is blocked by a hand or other body part, air may enter the bloodstream through the skin, resulting in a serious injury. All of the Air Nozzles and Jets manufactured by EXAIR have been designed for safety. All are safe to be supplied with higher pressure compressed air and meet OSHA standard 29 CFR 1910.242(b).
The table above shows the air consumption for typical homemade blowoffs.
Saving Money and Compressed Air
Consider the following example where a Model 1102 Mini Super Air Nozzle replaces a 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: 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).
- 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!!
- Standard Force Nozzles, group of air nozzles that produce up to 22 ounces (624 grams) of force, which is suitable for most applications.
- High Force Nozzles, group of air nozzles that produce up to 23 lbs (10.43 kg) of blowoff force where additional power and reach are needed.
- Back Blow Nozzles, ideal tool for cleaning closed tubes or where debris shouldn't be forced further into piping.
- Air Jets, produces a powerful, directed airstream that's ideal for part ejection or reaching hard-to-reach areas.
Build Your Own System
EXAIR's Swivel Fittings available for all our nozzles up to 1 NPT, make it easy to adjust the aim of the Air Nozzles and Jets. Correct placement of the blowing angle can help optimize performance, reduce noise levels and improve efficiency.
