Type 303 Stainless Steel - This is the most common grade of stainless steel. It offers good strength and is best suited to mildly corrosive environments. It can withstand temperatures up to 800°F (427°C).
Brass - general purpose applications. Max temp. 400°F (204°C)
Swivel Fittings - 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. Swivel Fittings permit a movement of 25 degrees from the center axis for a total movement of 50 degrees. Type 303 or 316 Stainless Steel.
Magnetic Bases - are suited to applications where frequent movement of the Air Nozzle or Jet is required. The powerful magnet permits horizontal or vertical mounting that will hold the blowing position of the Stay Set Hose. A shutoff valve is provided that can be used to vary the force and flow.

How EXAIR Air Nozzles Work
Air Nozzles use the Coanda effect to amplify compressed airflow up to 25 times or more. Compressed air 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.

- 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.
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 Energy savings can also be realized when replacing outdated compressor motors and controls with high efficiency models that often pay for themselves in a short period of time.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.
OSHA Maximum Allowable Noise Exposure
|Hours per day (constant noise)||8||7||4||3||2||1||0.5|
|Sound level dBA||90||91||95||97||100||105||110|
|OSHA Standard 29 CFR - 1910.95(a)|
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).
Stay SafeIf 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 MoneyOne 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%!

Saving Money and Compressed Air
Air Consumption of Open Tube and Pipe
|Pressure Supply||Air Consumption of Homemade Blowoffs|
|PSIG||BAR||Copper Tube||Open Pipe|
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.
- 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!
