Add Precision Aim and Flexibility to your Air Nozzle Installation with Swivel Fittings

Upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets can save as much as 80% of your compressed air usage when compared with an inefficient solution. An open copper pipe or tube, even if “flattened” as we’ll commonly see, wastes an excessive amount of compressed air. This wasted compressed air can create problems in the facility due to unnecessarily high energy costs and the pressure drop that can be experienced affecting other processes. In addition to simply using too much compressed air, an open pipe or tube will often produce sound levels in excess of 100 dBA. At these sound levels, according to OSHA, permanent hearing damage will occur in just 2 hours of exposure.

OSHA Chart

By simply replacing the open tubes and pipe with an EXAIR Super Air Nozzle, you can quickly reduce air consumption AND reduce the sound level. Sound level isn’t the only thing an OSHA inspector is going to be concerned about regarding an open pipe blowoff, in addition OSHA 1910.242(b) states that a compressed air nozzle used for blowoff or cleaning purposes cannot be dead-ended when using with pressures in excess of 30 psig. I don’t know if you’ve ever tried to use an air gun with 30 psig fed to it, but the effectiveness of it is dramatically reduced. This is why there needs to be a device installed that’ll prevent it from being dead-ended so that you can operate at a higher pressure.

EXAIR Super Air Nozzle entrainment

EXAIR’s Super Air Nozzles are designed with fins that serve two purposes. They help to entrain ambient air from the environment, allowing us to maximize the force and flow from the nozzle but keeping the compressed air consumption minimal. In addition, these fins are what prevents the nozzle openings from being completely blocked off. Using an OSHA compliant compressed air nozzle for all points where a blowoff operation is being performed should be a priority. Each individual infraction will result in a fine if you’re subject to an OSHA inspection. Inspections are typically unannounced, so it’s important to take a look around your shop and make sure you’re using approved products.

To ease the installation process, EXAIR manufactures a line of swivel fittings that allow you to position the blowoff precisely. Manufactured in either 303 or 316 stainless steel, the Swivel Fittings allow for movement of 25 degrees from the center axis for a total movement of 50 degrees. With no gaskets or seals to wear out, ther’es no added maintenance required to maintain optimum performance.

Swivels can be used on any of our Air Nozzles up to 1” and can also be used with the Adjustable and Super Air Amplifiers. By simply adding a “W” suffix to the part number, the correctly sized swivel fitting will be added to your order. For example, an 1122W would be one of our 2” Flat Super Air Nozzles with a ¼ NPT male x ¼ NPT female Swivel Fitting included. Stop wasting time trying to find the proper fittings and positioning for your blowoff nozzles! Contact an Application Engineer and get some of EXAIR’s Swivel Fittings and Super Air Nozzles on order today, available from stock.

Stay Set Hoses and Magnetic bases: adding flexibility to EXAIR products.

Mag Bases come with one or two outlets. Stay Set Hoses come in lengths from 6″ to 36″.

EXAIR manufactures a variety of intelligent compressed air products that can cool, clean, coat, convey, and conserve.  They’re designed specifically with enhanced efficiencies, OSHA safety, and high quality in mind.  What could make our products even better?  Making them movable, with the ability to aim them exactly where you need them!  EXAIR offers Magnetic Bases and Stay Set Hoses to achieve this.  In this blog, I will cover the features and benefits of both products.

Stay Set Hoses:

The Stay Set Hose gives you that possibility of manually adjusting and re-adjusting smaller EXAIR products like Super Air Nozzles and Air Jets.  The hose has a “memory” function, and it will not creep or droop until you physically move it.  They work very well in directing the air flows at specific target areas.  The Stay Set Hoses come in lengths from 6” (15cm) to 36” (91cm), and they have threaded connections with either ¼” NPT male on both ends or with a 1/8” NPT female X ¼” NPT male thread.  The hoses are made from reinforced synthetic rubber and have a pressure rating of 250 PSIG (17 bar).  They can add versatility to our Safety Air Guns and Blow-off Stations.  If you need positioning for precise blowing or adjustments for different targets, the Stay Set Hoses would be a nice addition to include with your EXAIR products. 

Magnetic Bases:

If you need a solid mount to steel surfaces or to move your blow-off system to different locations, the Magnetic Base will allow you to do these functions.  It has a 100 lb. (45.5Kg) pulling force to keep the blowing device attached firmly until you want to move it.  They can be mounted in a vertical or horizontal position.  EXAIR offers a single outlet Magnetic Base or a dual outlet Magnetic Base (for multiple blowing products). The bases come with a ¼ turn shut-off valve to easily turn on and off the compressed air to the EXAIR products. 

If you want to combine the Stay Set Hoses and Magnetic Bases with your EXAIR Air Nozzles and Air Jets, we can create this with the EXAIR Blowoff System.  We can combine multiple parts into a single model number.  At EXAIR, we pride ourselves with great customer service and an “easy to do business” philosophy.  You can contact a friendly Application Engineer to build an efficient, safe, and movable system just for you.

Benefits of Engineered Air Jets and Nozzles

EXAIR’s Engineered Air Nozzles and Air Jets provide a superior solution to minimize compressed air usage and reduce noise levels for compressed air blow-off operations.

Air Nozzles and Jets – when compared to commonly used open copper tubes or pipes the compressed air savings can be as high as 80%. With less compressed air, sound levels are greatly reduced.  A 10 dBA noise level reduction is typical.  All EXAIR Air Nozzles and Jets meet OSHA guidelines for dead end pressure and sound level exposure standards.
EXAIR Air Jets

EXAIR Nozzles and Jets are designed and manufactured to take advantage of the Coanda (wall attachment of a high velocity fluid) effect which can amplify the airflow up to 25 times. The compressed air exits through the small holes on the nozzle which entrains the surrounding air. The effect from this is a high volume, high velocity blast using less compressed air.  EXAIR manufactures many sizes and styles of air nozzles from the smallest, but quite powerful M4 x 0.5 thread Atto Super Air Nozzles to our largest 1-1/4 NPT Super Air Nozzle.  We also offer Flat Super Air Nozzles, and the Back Blow style nozzle for cleaning out tubes, pipes, channels or holes from 1/4″ to 16″ in diameter.

The Air Jets are 1/8 NPT threads and blow air out at a right angle from the inlet. They produce a vacuum on the larger diameter side which pulls in surrounding ambient air into the total output flow. Air Jets are available in brass or Type 303 stainless steel. You can choose from a fixed flow style or an adjustable flow style to provide flexibility for your applications. The adjustable flow models have a clear micrometer air gap indicator to assure consistent and accurate results.

All of our Air Nozzles and Jets  are engineered to meet or exceed OSHA Standard 1910.24(b) for 30 PSIG dead end pressure, they cannot be dead-ended as there is always a route for the air to escape. In addition, our products are going to meet the OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels.

EXAIR’s Flat Super Air Nozzles have been blowing away the competition since 2003.

EXAIR’s Swivel Fittings make it easy to adjust the position of the Air Nozzles and Air Jets.  The fittings allow for movement of 25° form the center axis for a total movement of 50°.  There are nine different models available and all of them are made from stainless steel

Improve Noise Exposure with EXAIR Flat Super Air Nozzles

EXAIR manufactures a variety of nozzles that are OSHA safe, high quality, and very efficient.  They are engineered to entrain the “free” ambient air into the air stream to create a powerful force while reducing compressed air usage.  Thus, saving you money.  With a multitude of blow-off applications like clearing small holes to quickly cleaning gantries on CNC tables, EXAIR has the nozzles for you.  In this blog, I will discuss the features and benefits of the EXAIR Flat Super Air Nozzles.    

The EXAIR Flat Super Air Nozzles are manufactured to blow a wide forceful stream of air.  Their patented design creates a high velocity, laminar air stream with minimal air consumption and low noise.  They come in two widths; 1” (25mm) and 2” (51mm).  EXAIR offers a standard Flat Super Air Nozzle and a High Power Flat Super Air Nozzle in two different materials, zinc-aluminum alloy and 316 stainless steel.  And with a metal construction, breakage is not a concern and performance are not sacrificed even in the harshest of environments. 

The unique patented shims used with the EXAIR Flat Super Air Nozzles will give you three improvements to the design and function.  First, they come in different thickness to create a wide range of forces.  In conjunction with a regulator, you can “dial” in the correct amount of force from a breeze to a blast without overusing your air compressor.  The patented shim also allows an even flow across the entire width of the air nozzle.  Unlike the plastic flat nozzles that use holes which generates a fluctuation of forces across the width.  Lastly, they help to entrain the free ambient air; so that less compressed air is required.  The high efficiency design will save you money.  The EXAIR Flat Super Air Nozzles are effective in uniform blowing with safety and efficiency in mind. 

To expand more on safety, I will direct you to Noise.  With “open” holes in nozzles, the compressed air is turbulent and loud.  The National Institute for Occupational Safety and Health, NIOSH, states that 70% to 80% of all hearing loss within a manufacturing plant is caused by compressed air.  OSHA created a chart to show the maximum allowable noise exposure.  This chart shows the time and noise limits before requiring hearing protection.  The EXAIR Flat Super Air Nozzles are designed to have laminar flow which is very quiet.  As an example, the model 1122 2” Flat Super Air Nozzle has a sound level of only 77 dBA at 80 PSIG (5.5 bar); well under the noise exposure limit for 8 hours.   

With the EXAIR Flat Super Air Nozzles, you can take advantage of the durability, safety, and efficiency for your blow-off devices.  With automated systems, or machine builders, you may want to look at the EXAIR brand for your blow-off, cooling, and coating applications.  The overall cost of your system as compared to the cost of the nozzles should not warrant the use of poor-quality plastic nozzles to save a couple of dollars.  Because in the long run, it will actually cost you more with loss of production, compressed air waste, very loud noises, and unsafe work environments. 

EXAIR stocks these nozzles for quick delivery.  If you are within the U.S. or Canada, they come with a 30-day unconditional guarantee to try them out.  If you need any help with our Flat Super Air Nozzles or how to build an optimum blow-off system, you can speak to an Application Engineer at EXAIR.  We will be happy to assist you.
