Need to Remove Stubborn, Sticky & Difficult Debris from a Surface? Try this.

Scrape off, and blow away, stubborn debris with the Model 1244-48 Soft Grip Super Air Scraper.

EXAIR has designed a new type of nozzle called the Super Air Scraper.  This nozzle combines a scraping blade with our 2” Flat Super Air Nozzle.  Together, it creates a mechanical force with an air force to remove stubborn sticky material.  This patent-pending nozzle can be added to the EXAIR Soft Grip Air Gun to create a powerful scraping tool. 

Model 1144 Super Scraper Nozzle

Let’s breakdown the nozzle.  The Super Air Scraper nozzle is a model 1144 which has a ¼” NPT female connection.  The model 1144-A includes a ¾ – 32 UN adaptor for connecting to the Soft Grip Safety Air Gun extensions.  The scraper can be changed when worn with a replacement blade; model 902007.  To add flexibility to the Super Air Scraper, a shim set, model 1132SS, can be used to modify the blowing force.  With these combinations, the nozzle complements the scraper as an effective way to clean with compressed air. 

Soft Grip Super Air Scraper

To control the pressurized air to the nozzle, EXAIR attached the 1144-A Super Air Scraper to the Soft Grip Safety Air Gun, model 1244.  This gives a comfortable and ergonomic way to use and operate this product.  We offer different extensions for hard-to-reach applications ranging from 6” (152mm) to 72” (1,829mm) in length.  With the extensions that are 36” (914mm) and longer, EXAIR installed an additional foam grip sleeve.  This gives additional leverage for scraping material at a distance like at the floor level.  Chip Shields are also offered to prevent blow-back onto the operator.  You can view the details of the new product at this link on our website: Soft Grip Super Air Scraper

To give some ideas for applications, the Soft Grip Super Air Scraper can be used for removing tape, gasket material, caulk, adhesive, paint, labels, and more.  With the addition of air, the detached material is blown away during scraping, keeping the area clean to target the remaining “stuck” material.  If gummy or flaky substances are a nuisance for workers, the Soft Grip Super Air Scraper can keep the machine or work station clean and operational. 

Just like all cataloged items for EXAIR, we stock these parts for same day shipment with orders placed before 2 p.m. EST.  For U.S. and Canadian customers, we offer a 30-day unconditional guarantee to see how great this product can work for your application.  If you have sticky, flakey, or greasy substances that need to be removed, the Soft Grip Safety Air Scraper is up to the challenge.  If you have any questions about the product or your “gummy” situation, you can contact an Application Engineer for help.

EXAIR’s Air Nozzles & Jets: The Engineered Alternative to Cheap or Homemade Blowoffs

If one of your goals is to reduce air consumption in your facility, look no further than EXAIR’s Engineered Air Nozzles & Jets. By upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets you can save as much as 80% of your compressed air usage when compared with an inefficient solution.

EXAIR’s engineered nozzles are designed to optimize your compressed air system by entraining ambient air along with the supplied air, providing maximum force on the target. Inefficient solutions are commonly used in the form of cheap, plastic nozzles and sometimes even worse, open pipes or tubes. 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.

By simply replacing the open tubes/pipe or inefficient solutions 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’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 unfortunate enough to be the victim of an unannounced OSHA inspection.

EXAIR carries a wide range of sizes and materials of nozzles, so you should have no trouble identifying one suitable for your application. Each is in stock and available to ship same day with an order placed by 2:00 ET. If the savings in compressed air alone isn’t enough incentive, some energy providers offer rebate programs for the implementation of an engineered compressed air nozzle. If you need help selecting the best nozzle for your process, give us a call. An Application Engineer is ready and waiting to help analyze your process and recommend the best option.

EXAIR’s Flat Nozzles Can Be Customized for Your Application

EXAIR’s Flat Super Air Nozzles provide a 1” or 2” wide airstream with hard-hitting force. All of EXAIR’s Flat Super Nozzles adhere to OSHA Standard 29 CFR 1910.242(b) for dead-end pressure, providing a safe and efficient method of delivering a strong blast of air.

The flow and force from the Flat Super Air Nozzle is adjustable by regulating the pressure supplied to it as well as by installing different thicknesses of shims. Thicker shims provide more force and flow, while a thinner shim will reduce the force and flow as well as the overall air consumption. This makes the Flat Super Air Nozzle and ideal solution for applications that may require variable force for different applications. Changing out the shim is fast and easy, check out this brief demonstration from one of my colleagues:

The nozzles are also available in your very own Blowoff System that can be customized to fit the exact application. You have the ability to put together the best combination of nozzle, Stay Set Hose, and Magnetic Base to suit your needs. Available with either a single or dual Magnetic Base and any of our Stay Set Hoses, there’s many different possibilities. To begin:

  1. Select the Air Nozzle you’ll need.

EXAMPLE: HP1125SS 2” High Power Stainless Steel Super Air Nozzle

  1. Then select the length of Stay Set Hose. They’re available in lengths ranging from 6”-36”.

EXAMPLE: An HP1125SS with a 24” Stay Set Hose would be an HP1125SS-9224.

  1. Finally, you have the option to also select a Magnetic Base if necessary. These are available with either a one outlet Magnetic Base, or Two Outlet which would include (2) separate nozzles. For a single outlet, change the second digit of the “added on” dash number to a “3”. For a two outlet, change that number to a “4”.

 EXAMPLE: An HP1125SS with 24” Stay Set Hose and Dual Magnetic Base is a Model HP1125SS-9424.

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
