EXAIR has designed a new nozzle called the Super Air Scraper. This nozzle combines a scraping blade with our 2” Flat Super Air Nozzle. It creates a mechanical force with a compressed 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.
Let’s breakdown the nozzle. The 2″ 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.
To get pressurized air to the nozzle, EXAIR attached the 1144-A Super Air Scraper nozzle to the Soft Grip Safety Air Gun. 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 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 3 p.m. EST. We offer a 30-day unconditional guarantee to allow you to see how great this product can work in your application. If you have a sticky, flakey, or greasy substance that needs 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.
I worked with a customer recently who was experiencing a static issue when trying to apply a bar coded label to their cardboard box. The boxes travel down a conveyor then passes by a labeler that uses a mechanical arm with air vacuum to hold the label in place. As the box passes by a sensor, the arm applies the label to the corner (front and side) and then the box passes by an applicator brush that ensures the label is firmly applied.
They were starting to see wrinkles in the label as it passed by the brush and were thinking the label was holding a static charge which was making it be rejected by the box during the process. They were experiencing this about every other box. When it would occur, they would need to stop the line and manually check to make sure the label was seated properly. As a result, this was negatively affecting their production time and increasing wasted labels.
Since they thought it was the label holding the static charge, they wanted to use one of our Ionizing Bars to remove the static from the label as it was attached to the arm. The Ionizing Bar produces a high concentration of positive and negative ions able to dissipate 5 kV in 0.30 seconds, 2” from the object’s surface. It is also UL listed for safety and RoHS compliant.
The customer is local, so they asked if someone from EXAIR could visit their location and take a look at their process. I was able to make the appointment for the next morning and brought a few of our Static Eliminating products and a Static Meter to take some measurements. By measuring within 1” of the surface of the product, the Static Meter measures the voltage and polarity up to +/- 20 kV.
Upon arrival, I was directed to the labeler and took a measurement – I was only getting a reading of about 0.2 kV. I then decided to take a reading on the box itself as it traveled down the conveyor. Now I was getting a reading of 3 – 5 kV, which meant that it was the box and not the label that was holding the static charge.
Since the customer could get within 2” of the surface of the box, they were able to mount a 6” Ionizing Bar vertically to remove the static prior to the labeling process. This helped to greatly reduce the downtime of the line.
With the first track day of the year under my belt it’s now time to start looking at what I could have done better and make the next track day an even bigger success. This will be done over the next month or so and I will use pictures, video, and even tire inspection to figure out what I could have done better. Much like a football team reviews tape and prepares for their next game.
Here at EXAIR we offer a service which is similar to this style of review. The EXAIR Efficiency Lab will let you send in your blowoff device and we will run it through the paces to find an intelligent compressed air product that will perform better than the previous method. This is a free service that we offer to any and all customers. Not only will we tell you what your unit is consuming and possibly costing you to operate but we will show you which of our products will perform the same and how much air and money you will save. The best part is it’s all for free.
If you have an application that you are trying to improve, let us know and we’ll get you the information to send a test piece in to the EXAIR Efficiency Lab.
