M4 Back Blow Nozzle Dries Inside Of Small Cylinders

A few weeks ago I received an inquiry from a customer who was looking to blow water off the inside of a closed cylinder after a zinc bonding process. There are 8 parts that are placed on a manifold which is then inverted and sent into their current blow off setup that includes small open tubes that get inserted into each cylinder to try and blow out the water. This setup worked a little but the issue they were experiencing was the airflow coming out of the tubes was blowing the water up, which caused it to collect in the “bowl” of the cylinder and as the blow off tubes were removed, the water would start to leak back out and down the inside walls again. After the current blow off, the parts are manually removed and inspected for moisture content. If the parts are found to be outside of their tolerances, an operator uses a modified blow gun fitted with a small tube to manually complete the process.

After discussing the particulars with the customer, their needs were two-fold – first they needed a nozzle that wouldn’t push the air toward the end of the tube but something that would direct the air “backwards” so as they placed the nozzle inside, they could hopefully “pull” the liquid out as the nozzle is removed. The second concern was the cylinder had a small 0.390″ diameter opening so the nozzle would need to be small and powerful enough to be able to fit inside the part, while still providing effective blowoff.

Once again, EXAIR offered the perfect solution, our Model # 1004SS M4 Back Blow Nozzle. The Back Blow Air Nozzle produces an even, 360° airflow that is directed away from the end of the nozzle. At only 0.20″ in diameter, The Model # 1004SS is the ideal choice for treating the inside diameter of small hose, pipe, bores (up to 1″) or in this case, small enough to fit inside the opening of the cylinder. With this design blowing the air back away from the end, the water wouldn’t get trapped in the bowl but rather would allow the inside walls of the cylinder to be wiped clean while directing the liquid toward the opening so the water can be removed.

In addition to the Model # 1004SS M4, we also offer our Model # 1006SS 1/4″ NPT Back Blow Nozzle for use with 7/8″ to 4″ ID’s, as well as our Model # 1008SS 1″ NPT unit for treating large ID”s up to 16″, for larger scale applications

The Model 1006SS cleans metal shavings from inside a pipe.

EXAIR’s Back Blow Nozzle is the perfect choice for cleaning or drying the ID of part or tube.

Even Our Customers Are Sending “Holiday Gifts”

Lately, it certainly has felt like Christmas here at the factory.  Two customers sent in some sample parts  for us to test and provide solutions for their application issues.  Opening the box is like unwrapping a present, what surprise will we find inside?

The first customer currently uses the Line Vac to convey (3) different parts from the floor to a hopper for the assembly process.  (2) of the (3) parts transfer very well, but the third conveys a little too slowly. Having all three parts here at EXAIR allows us to set up testing and determine what the root cause is and recommend a solution that will work equally well for all three parts.

The second is interested in our vacuum technologies to pick and place some fiber board material products.  Due to the curved surfaces and porous material, getting a good vacuum could be a challenge. By having the sample parts here, we can utilize our Demo Room, and try various E-Vacs with various vacuum cup designs and possibly the Line Vac or Air Amplifiers  to develop a good suction on each item.

When it isn’t possible to send in samples, we will stand behind the EXAIR Unconditional Guarantee – purchase a stocked catalog item, and you have 30 days to try it your facility, in your process, under your real world conditions.  If after the 30 days you aren’t satisfied, send it back for a full refund – and try something else!

To discuss your application and find out information about sending in material samples to confirm that an EXAIR Intelligent Compressed Air Product can help your process, feel free to contact EXAIR and one of our Application Engineers can help you determine the best solution.

Video Blog: How To Rebuild Pressure Regulators

Today’s video blog is a how-to on rebuilding EXAIR pressure regulators.   Regulators can wear out over time and extensive adjustment as well as if they are not used on a clean compressed air supply.  If you have any questions on an EXAIR product, please contact an Application Engineer.

Thanks for watching!

Mini Cooler Cools Hot Glue Beads

A few weeks ago I worked with a nail and staple gun manufacturer on a glue cooling process involving their collated nail strips. To keep the nails together, they place a small amount of hot glue across the body of the nails and then have an open air line blowing compressed air on the glue to secure a good bond between the pieces. The current process used to work great, but they recently made a change to the type of glue they were using and now they are starting to see more rejects as the heat from the glue isn’t able to be removed quick enough with ambient air. The customer is familiar with EXAIR as they currently use some of our other products in various applications throughout their plant but in this particular case, they were unsure of the best product to fit their needs so they reached out for assistance.

For this particular application, I suggested the customer use our Mini Cooler. The Mini Cooler is specifically designed for small area or small part cooling applications. The Mini Cooler uses less compressed air than our Cold Gun but still produces the same 50°F temperature drop from the incoming supply air temperature. So say your plant air is 70°F, you would see 20°F air being exhausted from the unit. The device features a flexible hose, allowing the user to focus the cold air to the desired location, in this case right at the glue which would provide the quicker, more reliable solution the customer was needing. Installation is a breeze as well, thanks to the included magnetic base, you don’t need to make any expensive modifications or add any type of mounting brackets to the existing setup.

The Mini Cooler is the ideal choice for small part cooling.

EXAIR offers a wide variety of spot cooling products that provide a low cost, maintenance free solution for large or small scale cooling processes. With help selecting the best product to fit your specific need or to discuss your particular application, please contact an application engineer for assistance.

High Temperature Capability

Last week, a customer called in to talk about their application.  After aluminum and steel machining operations, parts are run through a washer system. The drying portion utilized a Super Air Amplifier to dry the sides and a Super Air Knife to dry off the top. The wash temperature was running at 185°F.  The customer wanted to review the application and make sure the EXAIR products utilized in the process were rated to this temperature and to check on high the products could go, since the maximum possible temperature for the washer was listed as 250 °F.

Drying Section – Utilizing EXAIR Air Amplifier (near top) and Super Air Knife

The Super Air Amplifier is rated to 275°, above the maximum possible condition.  The Super Air Knife was pre-installed with a stainless steel shim, enabling a maximum temperature rating of 400 °F. Both of the components are rated for temperatures in excess of the maximum possible washer temperature condition, and the customer felt confident with the system design.

EXAIR has several options in the Air Amplifier and Super Air Knife product families to allow for operation in high temperature applications.  For the Air Amplifier, the Super Air Amplifier and Aluminum Adjustable Air Amplifier have a maximum temperature rating of 275°F.  The Stainless Steel Adjustable Air Amplifier is rated to 400°F, and for the hottest of conditions, the High Temperature Air Amplifier is rated to 700°F.

Relating to Super Air Knife, the aluminum Super Air Knife is rated to 180°F.  With a stainless steel shim installed, the maximum increases to 400°F. The PVDF Super Air Knife, used in applications where chemical resistance is needed, can withstand temperatures up to 275°F. And for the most extreme temperature environments, the Type 303 and Type 316 Stainless Steel Super Air Knives are rated up to 800°F.

To discuss your application and how an Air Amplifier and Super Air Knife or any EXAIR Intelligent Compressed Air Product can help your process, feel free to contact EXAIR and one of our Application Engineers can help you determine the best solution.
