Super Air Nozzles and Air Jets with Stay Set Hoses

Model 1126-9262

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

EXAIR’s engineered nozzles are designed to optimize your compressed air system.  Inefficient solutions are commonly used in the form of inexpensive nozzles and sometimes even worse, open pipes and tubes.  An open pipe or tube, even if “flattened”, wastes an excessive amount of compressed air and is not OSHA compliant.  The wasted compressed air can create problems in your facility due to unnecessarily high energy costs as well as pressure loss in your system; affecting other pneumatic processes.  An open pipe or tube will also produce sound levels in excess of 100 dBA.  At these noise levels, according to OSHA, permanent hearing damage can occur in just 2 hours of exposure.  If one of your goals is to reduce air consumption and improve safety in your facility, look no further than EXAIR’s Engineered Air Nozzles & Jets.

By simply replacing your efficient blowoff devices with an EXAIR Super Air Nozzle, you can quickly reduce air consumption AND remove safety issues.  Sound level isn’t the only thing an OSHA inspector is going to be concerned about regarding blowoff items and air guns.  OSHA 1910.242(b) states that “the use of compressed air for cleaning purposes at pressures at or greater than 30 psi is permissible if the outlet or source is fitted with a relief device that drops the pressure to less than 30 psi if the flow is dead-ended”. I don’t know if you’ve ever tried to use an air gun below 30 PSIG (2 Bar), but the effectiveness is dramatically reduced.  EXAIR’s Super Air Nozzles are engineered with fins that serve two purposes.  First, they help to entrain ambient air, allowing us to maximize the force and flow from the nozzle while keeping the compressed air consumption at a minimum.  And second, these fins will prevent the openings from being completely blocked off.  So, you can use EXAIR nozzles above 30 PSIG (2 Bar).  Using an OSHA compliant compressed air nozzle in a blowoff operation should be a priority because each individual infraction from OSHA will result in a fine if you’re unfortunate to be visited by an unannounced inspection.

To add versatility to the EXAIR Air Nozzles and Jets, we offer Stay Set Hoses.  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 maximum pressure rating of 250 PSIG (17 bar).  If you need positioning for precise blowing or adjustments for different locations, the Stay Set Hose would be a nice addition to include with your EXAIR Air Nozzles.

One of the last things that companies think about when using blowoff devices is safety.  OSHA regulations regarding loud noises and dead-end pressure can be missed.  To stop any future fines, it is important and more economical to purchase EXAIR products.  If you would like to improve the safety in your facility and save money with your current blow-off devices, an Application Engineer at EXAIR can help you select the appropriate solution.

Don’t Forget the Hoses – Benefits for Compressed Air Applications

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 find the proper diameters, pressure ratings, and end fittings that will work and maximize the performance.  EXAIR has them in stock and ready to ship. In this article, I will go over the different types of hoses and tubes that EXAIR can offer.

Coiled Hose

Coiled Hoses: 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 Hose

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.

Flexible and durable, EXAIR Stay Set Hoses come in lengths from 6″ to 36″.

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 applications, the Stay Set Hose would be a nice addition to your equipment.

Conveyance Hose – 3/8″ – 3″

Conveying Hoses: 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 non-threaded style of the EXAIR Line Vacs.  EXAIR can cut-to-length Conveying Hoses up to 50 feet (15m); in increments of 10 feet (3m).

Vacuum Hose

Vacuum Tubing: 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 vacuum hose is very flexible for moving product, and they can resist the vacuum pressures created by the E-Vac.  They slip into our Push-In Connectors to quickly attach vacuum cups to the E-Vac system.  EXAIR can sell both sizes 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.

Optimize Your Intelligent Compressed Air® Products with EXAIR’s Accessories

EXAIR offers a wide variety of various accessories that can help you to better control and fine-tune any of your compressed air operated products. Most of EXAIR’s line of Intelligent Compressed Air Products have no moving parts and require no maintenance. The caveat to the “no maintenance” aspect is proper filtration at the point of use. Many products have very tight orifices that could get clogged from any contaminants such as particulate, condensate, and lubricant. EXAIR recommends point of use filtration to be installed just upstream of any EXAIR Product for this purpose.

EXAIR has a line of Automatic Drain Filter Separators and Oil Removal Filters, available from stock, to make sure the quality of your air supply is sufficient for proper operation of any EXAIR product. Particulate filters remove any suspended solids from the airstream, ensuring the tight orifices in the products remain free of debris. If your system has residual oil, this should also be removed with a coalescing filter. Check out this short video from my colleague, Brian Farno, that demonstrates these filters in action:

Controlling your compressed air pressure at the point of use is an excellent way of minimizing your compressed air usage. Pressure regulators are available to control the air pressure within the system and throttle the appropriate supply of air to any pneumatic device. As the last of the six steps to optimizing your compressed air system, controlling air at the point of use can often be overlooked. using them to minimize your pressure can result in dramatic savings to your costs of compressed air. As pressure and flow are directly related, lowering the pressure supplied results in less compressed air usage. EXAIR recommends operating your Intelligent Compressed Air Products at the minimum pressure necessary to achieve a successful application. If you notice a desirable result at a pressure of 60 PSIG, or even less, there’s no need to run full line pressure. In-line point of use pressure regulators are the simplest and most reliable way to allow you to dial down to the pressure to any compressed air operated product.

Taking this idea of minimizing air usage one step further, you can achieve even greater savings by simply turning the air off when not needed. The most basic option for turning off the air supply is a simple manual valve. EXAIR offers a range of various sized valves to allow you to do just that.

This process can also be automated as well. If you’d like to automate the control of your blowoff, EXAIR offers solenoid valves that can tie into your existing PLC and eliminate unnecessary air usage. For those that want a solution ready to go right out of the box, EXAIR’s Electronic Flow Controller utilizes a photoelectric sensor and solenoid valve tied to a timer that allows you to shut off the air supply when a part or component is not present. This can lead to dramatic air savings in many applications where parts are traveling along a conveyor.

Once you’ve selected an engineered compressed air nozzle for your blow off application, you’ll likely need a solution to mount and position it as well. 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 repositionable as well, making them an ideal solution for applications that may require frequent repositioning due to varying parts.

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.

Regardless of your application, EXAIR has the products available from stock to help optimize your processes. These accessories allow you to help optimize the use of your blowoff products and ensure reliable, repeatable performance. If you’d like to discuss an application, give us a call.

EXAIR Chip Shield Sizes and Selection

EXAIR has many options when considering Air Nozzles, Air Jets and Safety Air Guns. When considering the safety in using these tools one should consider the extra protection that EXAIR Safety Shields offer. Let’s look at the options and sizes of our Chip Shields.

EXAIR Chip Shields are durable polycarbonate shields that can be used with or without extension pipes. The Chip Shield, as the name suggests, protects the operator from flying debris such as metal chips, shavings and liquid coolants. The use of Chip Shields help meet the requirements of OSHA 1910.242(b) for safe use of compressed air.

If you are ordering a new Safety Air Gun from EXAIR and need a Chip Shield you simply place a “-CS” after the Safety gun model number, For example if you order Model 1210 VariBlast Compact Safety Air Gun (SAG) and want a Chip Shield you would order Model 1210-CS and EXAIR will automatically know the size of the shield and will ship the Safety Air Gun and properly sized Shield. If you would like the same gun with a 12″ extension you would order as such; 1210-12-CS and you will receive the Model 1210 VariBlast SAG with a 12″ Aluminum extension and Chip Shield.

If you have a SAG with an extension pipe and want to add or replace a Chip Shield then we must consider the extension pipe and nozzle NPT. All of the Chip Shields are the same size with the exception of the center diameter and the rubber grommet which will accommodate the NPT size of the Air Nozzle and extension. Here is a list of the replacement shields:

If you have a SAG and do not have an extension pipe or shield we have Chip Shield Kits that will allow you to retrofit your existing gun:

One important note is that SAG’s that are equipped with a Stay Set Hose will not allow for the Chip Shield to be installed. Choosing the correct Chip Shield or Retrofit Kit can be tricky but EXAIR Application Engineers are always ready to help.
