Ever had that spot that you needed to blow off but no matter how hard you tried you couldn’t reach the spot with piping? Well here at EXAIR we’ve got a solution for you; Introducing the swivel fitting! When blowing off various parts it is better to have an angled sweep of air rather than blowing directly across or directly down onto the part. EXAIR’s Swivel fittings provide a movement of 25 degrees from the center, meaning a total of 50 degrees.
For more information on EXAIR’s Swivel Fittings, Stay Set Hoses, or any EXAIR‘s Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

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 them perform even better? Making them movable! 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 and a ¼” NPT male types.
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 Blowoff 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.
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). We also have a Magnetic Base with a swivel to help angle the blowing force. 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 devices 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.
Throughout my years here at EXAIR as well as my years in the metal cutting industry, one of the most common quick fixes I see in production environments for compressed air blowoffs in a process is an open copper pipe that is contorted into a position, pinched at the end, and more often than not kinked from repositioning. I call this a quick fix because it does blow air, more often than not it will get production up and running, but it does not meet or exceed OSHA standards for safety and is an inefficient use of compressed air. [OSHA Standards 29 CFR 1910.242(b) and 29 CFR 1910.95(a)]
The first engineered solution I could offer to prevent any costly OSHA fines and to lower the ambient noise level caused by these blowoffs is to implement an EXAIR Engineered Air Nozzle. We offer a wide variety of nozzles ranging from a 4mm thread up to a 1-1/4″ NPT thread. With this wide range comes a wide variety of forces and flows as well.
Today, I would like to focus on the common sizes of copper blowoffs which are 1/8″ and 1/4″. To simply adapt a nozzle to copper line a compression fitting can be easily sourced, often from EXAIR, and convert the copper tubing in place to an NPT threaded outlet for easy installation of an EXAIR nozzle. More often than not a compression fitting is how the copper tubing is tied into the machine’s compressed air system.
We have a total of 37 engineered air nozzles from stock that will easily fit a compression fitting which goes to a 1/8″ NPT or 1/4″ NPT thread. Several of these are also adjustable through a gap adjustment or a patented shim adjustment to vary the force and flow out of the nozzle from a forceful blast to a gentle breeze in order to me your application needs. What if you want to eliminate the copper line and compressions fittings?
EXAIR offers a replacement option for the ever-common copper tube that is more robust and does not require a tool to be properly repositioned. We currently offer twenty-four different models of our Stay Set Hoses that can be easily connected to any of the nozzles mentioned above. The lengths that are available are 6″ (152mm), 12″ (305mm), 18″ (457mm), 24″ (610mm), 30″ (762mm) and 36″ (914mm).
These lengths are available with two separate connection options. 1/4″ MNPT x 1/4″ MNPT or 1/4″ MNPT x 1/8″ FNPT. The Stay Set Hoses can easily be bent by hand into position for a precise placement of the air pattern from the engineered nozzle attached to it. This permits operators a tool free adjustment for fast and reliable location to keep production up and running. They can also be paired with Magnetic Bases.
EXAIR Magnetic Bases are available in single outlet or dual outlet configurations. Both include a 100 lb. pull magnet that will hold tight to any ferrous metal surface for secure mounting, as well as a quick 1/4 turn miniature valve on each outlet. This permits independent customization of the force our of each output for the dual outlet mag base. Each magnetic base offers a 1/4″ FNPT inlet port and outlet port. We offer these with any of combination of the Stay Set Hoses mentioned above as well as any of the Super Air Nozzles mentioned above.
The Super Air Nozzles, Stay Set Hoses, and Magnetic Bases can be easily combined before they ship to your facility to make a complete blowoff station that is easily installed and adjusted to fit any of the needs your process may have for a point of use blowoff. If you want help determining how much compressed air you would save by replacing the open pipe blowoffs with an engineered solution like a Stay Set Magnetic Base Blowoff System please contact myself or any Application Engineer here at EXAIR.
I recently worked with an company that performs energy audits and they were working with a food company to review and propose ways to reduce the energy consumption throughout the plant. One area where we were able to help was on an onion peeling machine, shown below:
The area of machine in question used a screw conveyor and friction source to help loosen the peels and fifteen (15) 1/4″ O.D. open ended tubes, which were noisy and unsafe, to blow the peels completely off and away form the onion. The auditor was able to install an air flow meter on the system and found that the machine was consuming 220 SCFM of compressed air for this operation.
We proposed to replace the tubes with a 6″ Stay Set Hose and the model 1103 Mini Super Air Nozzle. Each model 1103 Mini Super Air Nozzle will consume just 10 SCFM of 80 PSIG compressed air. Attached to the 6″ Stay Set Hose, the nozzle can be placed exactly where needed and aimed appropriately. A strong blast of air rated at 0.56 lbs (9 ozs.), and ultra quiet at 71 dBA, the Mini Super Air Nozzle delivers the results needed.
The Stay Set Hose has “memory” and will not creep or bend, simply install the 1/4 NPT fitting into the compressed air supply side, an thread the 1/8 NPT Mini Super Air Nozzle into the other end and position as needed!
Fifteen (15) of the Mini Super Air Nozzles will pass 150 SCFM of compressed air compared to the current usage of 220 SCFM, resulting in a 70 SCFM drop, or a 31.8 % reduction. At a typical cost of $0.25 per 1000 Cubic Feet of Compressed Air, the nozzles would save $1.05 per hour of operation. Rate of Return yields a full pay-off in just 43 days of operation (24 hours per day operation)!
If you are looking for ways to save on compressed air usage in your facility that is safe to operate and quiet to use, we will have a solution for you.
If you have questions about any of the 16 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.
EXAIR offers different styles of hoses and tubes as accessories to our product lines. They are built and designed to easily fit with our products as well as being sized correctly to not affect performance. It simplifies the use, setup, and integration of EXAIR products in your facility. You do not have to determine the proper diameters, pressure ratings, or end fittings to best fit the EXAIR products to maximize their performance. Also, having these items available from one source minimizes the number of purchases and vendors necessary for a complete and working solution. In this article, I will go over the different hoses and tubes that EXAIR can provide.
The hoses above are used with our Air Operated Conveyors or Line Vacs. The Line Vacs are designed to move product from point A to point B. If the Line Vac is the “vehicle”, the Conveyance Hose is the track. The hoses are made of a durable PVC semi-flexible hose with 6 different diameters from ¾” I.D. to 3” I.D. The conveyance hose can slip easily onto the EXAIR non-threaded style of Line Vacs. EXAIR can cut-to-length Conveying Hoses up to 50 feet (15m); in increments of 10 feet (3m).
To get compressed air from the piping system to the Safety Air Guns, we offer a series of Coiled Hoses. They are made of a durable abrasion-resistant nylon material that is 12 feet long (3.6 meters). They have swivel fittings to allow for easy uncoiling, and a spring strain relief to keep the hose from kinking. The coiled design makes it easy to reach around the work area and retract back to the substation. This will help to keep the hose off the ground where potential dangers could occur. We offer 3 different connection sizes of 1/8” NPT, ¼” NPT, and 3/8” NPT to attach right to the Safety Air Guns. With the proper size, the Coiled Hoses can supply the required amount of compressed air with a minimal amount of pressure drop.
Compressed Air Hoses:
If you need a compressed air line to reach from overhead or around equipment, the EXAIR Compressed Air Hoses would work with these applications. They are made from a reinforced synthetic rubber in 3/8” I.D. and 1/2” I.D. diameters. We can make specific lengths up to 50 feet (15m). They are rated for 250 PSIG (17 bar) air pressure, and the hose material works well for long lasting protection against ozone, weathering and temperatures up to 158oF (70oC). They come with two male ends in ¼” NPT or ½” NPT.
Stay Set Hoses:
The Stay Set Hose gives you that possibility of manually adjusting or re-adjusting Super Air Nozzles. The hose has a “memory” function, and it will not creep or droop until you physically move it. They work well to direct air flows in specific target areas. They can be used with Super Air Nozzles, Safety Air Guns and Blow-off Kits. The Stay Set Hoses come in lengths from 6” (15cm) to 36” (91cm), and they are offered with ¼” NPT male on both ends or with a 1/8” NPT female and a ¼” NPT male connections. These hoses are rated for 250 PSIG (17 bar) and are made from reinforced synthetic rubber. If positioning is required for accurate blowing or re positioning for different areas, the Stay Set Hose would be a nice addition to your equipment.
For our E-Vac product line, EXAIR offers vacuum hoses to connect the E-Vac vacuum generators to the suction cups. They are made from polyurethane in ¼” O.D. and 3/8” O.D. The tubing is very flexible for moving product, and they can resist the vacuum pressures created by the E-Vac. They slip easily into our Push-In Connectors to quickly attach vacuum cups to the E-Vac system. EXAIR can sell both types of tubing up to 50 feet (15m) in increments of 10 feet (3m).
Hoses and tubes may seem like simple things, but EXAIR already did all the research in determining the best material and correct size for optimum performance. You can leverage this information to save you time and money when using EXAIR products in your application. If you need help in selecting the correct model, you can contact an Application Engineer. We will be happy to help you.
Once you’ve selected an engineered compressed air nozzle for your blowoff application, you’ll likely need a solution to mount and position it as well. In some applications you may be able to simply replace the old solution with a similar thread, but if the installation is a bit more complex, or if it is a new installation entirely, you’ll need a means to do so. Here’s where EXAIR’s Stay Set Hoses and Magnetic Bases come into play.
EXAIR’s Stay Set Hoses are available from 6”-36” in length with ¼ NPT male threads on each end, or a ¼ NPT male on one end and 1/8 NPT female on the other. The Stay Set Hoses are rigid and allow you to maintain precise positioning of the blow off nozzle. The hoses have “memory” and will not creep or bend. They’re easily repositioned as well, making them an ideal solution for applications that may require moving them around due to varying parts.
Stay Set Hoses can also be installed on any Soft Grip Safety Air Gun. Simply adding a suffix to the end of the any of the Soft Grip Air Gun model numbers will come with the Stay Set Hose installed. For example, the gun below is a Model 1230-36SSH. A Model 1230 Safety Air Gun, with a 36” Stay Set Hose installed. Having a Stay Set Hose on your air gun can allow you to reach into tight or awkward places that a traditional air gun won’t permit.
In addition to the Stay Set Hoses, EXAIR also has Magnetic Bases available as well. The powerful magnet permits both horizontal and vertical mounting. A manual valve is also included that will allow you to vary the force and flow. Magnetic bases are available with one or two outlets and can be combined with any of our nozzles and Stay Set Hoses to create your own customized blowoff system.
No matter the application, EXAIR has a solution for your blowoff. Give an Application Engineer a call today and we’ll help you determine EXACTLY what you’ll need with all parts available from stock!
EXAIR manufactures a variety of nozzles that are OSHA safe, high quality, and very efficient. In this blog, I would like to discuss the features and benefits of the EXAIR Flat Super Air Nozzles and how to build a system to fit your application.
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 sizes; 1” (25mm) and 2” (51mm), and EXAIR stocks them in two different materials, zinc-aluminum alloy and 316 stainless steel. With a metal construction, breakage is not a concern and performance is not sacrificed even in the harshest of environments. I have seen many plastic flat nozzles that were broken in applications. The noise level was loud, and compressed air was wasted. The unique patented shims inside the EXAIR Flat Super Air Nozzles give three improvements to the design and function. First, they come in different thicknesses 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 hurricane without overusing your air compressor. The patented design also allows an even force across the entire width of the air nozzle. 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; efficient; and superior in quality and durability. You can watch a video blog on the importance of using our patented shim.
To show the different types and styles of Flat Super Air Nozzles that EXAIR stocks, you can correspond to the model number make-up sheet below.
To give force adjustments to the individual Flat Super Air Nozzles, EXAIR offers a way to change the thickness of the shim to better suit your application. You can increase or decrease the force of the nozzle by just removing two screws and changing the shim inside. This is a unique feature as most competitive flat nozzles do not allow you to do this. EXAIR offers different thicknesses of the patented shims in our Shim Sets. The chart below corresponds the appropriate Shim Set to the Flat Super Air Nozzle.
What can make the Flat Super Air Nozzles even better? More flexibility. The Stay Set Hoses can add that flexibility to the Flat Super Air Nozzles. They are designed to manually position the Flat Super Air Nozzle to accurately target the air stream. They allow maneuverability to locate the nozzle at different heights or angles; and once positioned, the Stay Set Hose will hold the nozzle in place. They come in different lengths from 6” (152mm) to 36” (914mm). We carry two different styles of connections to adapt to any of the Flat Super Air Nozzles. You can select the different lengths of Stay Set Hoses (SSH) to the Flat Super Air Nozzle by the model number make-up sheet below.
To build your system even further, EXAIR also can offer a Magnetic Base to your Stay Set Hoses and Flat Super Air Nozzles. The Magnetic Base has a powerful magnet on the bottom to securely attach the blow-off nozzles vertically or horizontally. This feature is great if you need to move the nozzles to different areas in your application. EXAIR manufactures a one-outlet and a two-outlet design. Each outlet has a ¼ turn valve to manually turn on or off the nozzle and only require one air supply inlet. To add this product to the Flat Super Air Nozzle with the Stay Set Hose, you can use the model number make-up sheet below.
With the EXAIR Flat Super Air Nozzles, you can take advantage of the durability, safety, and efficiency for your blow-off device. In addition, you can build a system that will best suit your requirements. You can add different lengths of Stay Set Hoses and/or different Magnetic Bases. With these combinations grouped into one model number and in stock for quick shipments, it makes it simple to purchase from EXAIR. Just to let you know, they also come with a 30-day unconditional guarantee to try them out. If you need any help in building your optimum blow-off system, you can speak to an Application Engineer at EXAIR. They will be happy to assist you.
