Model 1109-PEEK Solves Customer Dilemma

1109-PEEK

1109-PEEK Nozzle used in non-marring blowoff application

In a recent application for a new installation, an end user of EXAIR products needed a way to remove defective material from a production line.  At times, the defective items would fall along a conveyor, and the end user wanted to install an effective, efficient blowoff system to address multiple points along the conveyor.  Further to the complexity of the application, the end user needed a product that would not damage the product any further, as they reworked those items to reduce total scrap rates.

Initially, we considered a series of PVDF Super Air Knives, one of which could be triggered “ON” when material was detected.  But, the material size is relatively small, leading to the installation of many, many small Super Air Knives.  This solution was viable from a performance perspective, but further review found a more economic solution.

We then considered Super Air Nozzles.  Perhaps a series of small, efficient nozzles, controlled in groups of (5) or (10), could provide the desired blowoff force.  But, what about the need to not damage the product if in contact with the blowoff device?

This is where the PEEK plastic, model 1109-PEEK, became a perfect fit.  A series of 1109-PEEK nozzles provided the necessary blow off force, consumed minimal compressed air, and provided a non-damaging, non-marring solution.  When controlled in clustered groups, the specific section of the conveyor could be cleared of the defective material, blown into bins for reworking.

These attributes of the 1109-PEEK nozzle, along with high chemical resistivity, and a high temperature range (up to 160°C / 320°F) make it a viable choice for a variety of applications.  Maybe that’s why it is currently nominated for a Plant Engineering Product of the Year Award in the Compressed Air category – Please VOTE for the Precision Air Nozzle here.

EXAIR Application Engineers are well versed in the parameters of our products and a wide range of industrial applications.  If you have a need for engineering support in your application, contact an EXAIR Application Engineer.

Our Air Savings Calculator will show you total dollars saved and payback time.

Our Air Savings Calculator will show you total dollars saved and payback time.

Our knowledge base features the CAD Library, Case Study Library, and Application Database. The Air Data Library is invaluable to any engineer specifying a compressed air piping system. It also features a great article for calculating air consumption at various inlet pressure. One of my favorite features though is the Air Savings Calculator.

The Air Savings Calculator allows you to calculate the cost of compressed air for various devices.  The cost of compressed air for high usage device like open blow offs, drilled pipes and uncontrolled compressed air devices can add up quickly. With the air savings calculator, you can quickly find out how much those (8) 1/16″ inner diameter 18″ long open pipes are costing you per year ($2,016 if you are operating at 80 PSIG).

Some of the material that we make available to our visitors we request that you register on the site. The registration is a simple process to complete. Why would you want to take the time to give us you information? First, registering on EXAIR’s site gives access to our library of product applications for the last thirty years EXAIR has tracked how our products have been used to help our customers solve their industrial needs. Second, EXAIR members are granted access to CAD models in 2D and 3D of our products. The 3D models can easily import into AutoCAD Inventor®, Solidworks®, or PRO Engineer®. These models will allow you to easily import EXAIR products into your design to verify the fit and mounting in complex systems. Third, EXAIR Case Study library offers detailed analysis of economics, safety, and utility savings of using EXAIR products.

What is the USB Data Logger for Digital Flow Meters? How Can It Help Me?

USB Data Logger

The USB data logger works with all of EXAIR’s Digital Flow Meters and provides valuable feedback for optimizing your compressed air system.

EXAIR’s Model 9147 USB Data Logger has become one of the most valuable tools that we sell to help customers get a “view” of their compressed air usage over time. One of the important tenets we promote at EXAIR is energy savings by prudent use of compressed air through our engineered solutions (Air Knife, Air Nozzles, Air Amplifier, etc.). But how does a person in charge of such systems really “know” whether they are helping or hurting their compressed air system?

The first step is to have an appropriate flow meter which can give an indication of how much air volume is being used. EXAIR’s line of Digital Flow Meters are perfect for getting to that point with instant and direct readings that don’t need to be calculated any further. What you see on the meter is the flow in either SCFM or m3/hr calibrations.

The second step is to attach the USB Data Logger to the Digital Flow Meter so that readings can be kept over time. It is like setting up a security camera for your compressed air system. Nothing gets by without being recorded.

The USB Data Logger can be connected to just about any type of monitoring system that has a 4 – 20 mA output to which the 2-wire harness can be installed. A quick and easy initialization to choose the unit of measure, to select the frequency of measurement and some optional alarms is all that is necessary. The software package is included with the USB Data Logger and is convenient to run on a typical desktop or laptop computer. You simply, set it and forget it (at least until you want to do some reporting).

The reporting is how the USB Data Logger can help you as the person concerned with monitoring the compressed air use in your facility. Once the defined monitoring period of time has passed, the USB Data Logger can be removed from its socket, stopped from recording and the data is then downloaded into a suitable format that can be imported into EXCEL or other spreadsheet program for creating charts to analyze what is happening, when it is happening and how much compressed air is being used. In the analysis, you can compare the flow data and times with certain problems in a production line that might cause low pressure condition which shuts machinery down. You might also be able to determine where additional, point of use compressed air storage might be needed close to certain processes.

Ultimately, the USB Data Logger allows you to “see” your compressed air system in a way that allows you to sleuth out problems seen that might have no other explanation. It can also help you to justify your air savings when you apply the other air saving compressed air products that EXAIR produces by monitoring a base line for “before” performance and “after” performance. After all, it if is important to your organization, it should be measured. And compressed air is certainly a utility that should be measured.

Ordering Off The Menu, Revisited

I wrote a while back about ordering off the menu, in regard to technical data on EXAIR products. I’d like to share another example of how we can help, if you don’t find just what you’re looking for in our catalog.

I recently had the pleasure of helping a new Line Vac customer – a machinery builder – who needed a combination of properties of two different products: the stainless steel construction of the 2” NPT Threaded Line Vac, but the performance of the 2” Heavy Duty Threaded Line Vac. The Installation & Operation Guide actually gives you instructions on drilling out the generator holes for increased air flow & performance, but they didn’t want to disassemble, modify, and reassemble the units if they didn’t have to. Which was fine with us – we were able to perform these modifications in assembly, and ship them, surprisingly quickly (surprising to our “new” customer anyway…) and they were quite pleased with the results. So much so, that the modified Line Vac is now standard equipment on this new machine.

Which of these Line Vacs has higher performance?  We can't be sure without checking the generator!

Which of these Line Vacs has higher performance? We can’t be sure without checking the generator!

We get a fair number of calls about products or applications that don’t EXACTLY fit the parameters, specifications, and performance ratings of our catalog products. Some of them simply won’t work…and we’ll tell you. Other times, though, we’re able to put our Design, Production, and Application Engineering skills to the task, and hit one out of the ballpark. And we’re set up to do it better than anyone else.

If you’d like to discuss a compressed air products application that’s a little (or a lot) “off the menu,” give us a call.

Full-Flow Air Knife Assists With Flour Recovery

I took a call from a customer who was looking for a way to recover residual corn flour on their chain and paddle, drag conveyor. As the paddles moved down the line, they would start accumulating flour which was leading to uneven batch runs and waste. After reviewing the application with the customer, they determined they were only needing to blow off the width of the paddles, so I recommend using our 18” stainless steel Full-Flow Air Knife.

The Full-Flow Air Knife provides a 30:1 amplification rate (entrained air to compressed air), to produce a high velocity curtain of air that travels the entire length of the knife. With a small profile of only 1” H x 1.25” W, the unit is the ideal choice where mounting space is limited. It is available in a 303SS material which was suitable for this wash-down application.

Full-Flow

The Full Flow Air Knife is available in aluminum or stainless steel construction, up to 36″ stocked lengths.

 

Due to the concern regarding dust, I recommended operating the unit at a gentle 20 PSIG, lowering the velocity to 3,000 FPM and reducing the air consumption to only 1.1 SCFM per inch. A simple pressure regulator is capable of adjusting the volume and velocity of output airflow in order to “fine tune” our knives per application. This would allow for the needed blowoff, as well as reduce the potential of the unwanted dust.

If you have a similar application or would like to discuss your process, please don’t hesitate to give us a call at 1-800-903-9247.

Super Air Wipe Blows Wire Clean After De-scaling Process

saw-application

We had a customer recently who processed wire rod. Part of their processing includes de-scaling and polishing the outside of the wire. Their problem was that at the out-feed of the polishing machine, they were getting a lot of carry-out of grit and scale from the wire de-scaling and polishing process.

To counter the problem of carry-out, they decided to mount model 2400 ½” diameter Super Air Wipe at the out-feed section of the machine in order to blow back all the debris and scale into the machine where it could be collected nicely by a drawer in the bottom of the machine base. Prior to installing the Super Air Wipe, the customer would have to clean up piles of debris outside the machine. Now it is all contained nicely within.

Do you have an application where you are processing a continuous, round, extruded material that needs to be cleaned, dried or blown off?  If so, the Super Air Wipe is an excellent choice to provide the full 360 degree wipe around the outside of the material.
