Shim sets for the 1" High Power Flat Super Air Nozzles include a .020" (0.51mm) and .030" (0.76mm) thick shim. A .025" (0.64mm) shim is factory installed in the Model HP1126 and HP1126SS 1" High Power Flat Super Air Nozzles.

Selecting the Right Air Nozzle

EXAIR manufactures a wide selection of Air Nozzles and Jets, which are divided into two groups. The first group of Standard Force Air Nozzles includes Air Nozzles and Jets that deliver force up to 22 ounces (624 grams) and are suitable for most applications. The second group of High Force Air Nozzles includes Air Nozzles that produce high force up to 23 lbs (10,43 kg) where additional reach and force are required.

  • Type 303 Stainless Steel - high temperatures and corrosive environments. Max temp 800°F (426°C)
  • Type 316 Stainless Steel - high temperatures, corrosive environments, and mechanical wear. Max temp 1000°F (538°C)
  • Brass - general purpose applications. Max temp 400°F (204°C)
  • Zinc - aluminum alloy- general purpose applications. Max temp 250°F (121°C)
  • PEEK - replaces metals in harsh environments. Offers chemical resistance and is non-marring. Max temp 320°F (160°C)

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.

Air Nozzle
Turbulent compressed air blasts straight out of the pipe or tube. It not only wastes huge amounts of compressed air but also violates 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 Energy savings can also be realized when replacing outdated compressor motors and controls with high efficiency models that often pay for themselves in a short period of time.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.

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.

  1. 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).
  2. 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).
  3. Compressed air saved = 70 - 10 = 60 SCFM (1,981 - 283 = 1,698 SLPM).
  4. 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).
  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, $0.25 is a reasonable average to use. (Cost per 10,000 standard liters is approximately $0.089.)
  6. 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)
    1. = $0.90/hour
    2. = $0.90/hr. is $36.00/week and
    3. = $1,872.00/year savings  for One nozzle!
