ROI – Worth Looking at the Details

ROI or Return On Investment is a way to gauge the productivity or profit/loss from money spent on an investment. In business, companies will use this information to determine if a project or investment is worth the risk, ultimately leading to a net profit gain as the end result.

Don’t waste your money

In my own personal experience, my wife and I were considering buying into a timeshare vacation property a few years ago. To enter into the agreement, the company required a $ 22,000 “buy-in” (financed of course) and a recurring cost of approximately $60/month for the next 22 years. This would have afforded us 124 “points” for nightly stays on our planned vacation. Their timeshare rentals are tiered into different room types – Studio, 1 bedroom, 2 bedroom or a 3 bedroom villas – with each room type costing a certain amount of points. For us to maximize the length of our stay, we would have to select the studio room which would have given 6 nights at a total of the 124 points.

We have visited this popular vacation destination several times so we know what the average cost is to spend a week on property and purchase theme park tickets for our stay. When we booked on our own, we spent on average a little less than $ 3,000 for 7 days which included our room each night and 6 day park passes per person.

The timeshare rental cost was just for the nightly stay, it didn’t include any park tickets, food or other recreations. On average, the cost for 6 days worth of park passes per adult is close to $ 450.00 and per child it was around $ 400.00. Considering there are 2 adults and 1 child (at the time) we had to pay an additional cost of $ 1,300.00.

So if we joined the timeshare and stayed for 1 week once a year, it was going to cost us approximately $ 3,020.00 ($ 1,720.00 (timeshare cost) + $ 1,300.00 in tickets). In this case, it was actually going to cost us MORE in the long run than if we booked a yearly vacation on our own (< $3,000), leading to a negative ROI. (not to mention, I really didn’t want to commit to the same vacation for the next 22 years!).

When discussing replacement compressed air blowoff solutions with a customer, many times they look at the purchase price of the device and question if it’s worth it for them to make a change. If you follow along with our blog, you will notice that over the last few months we have submitted several different entries relating to this topic, like replacing drilled pipe with our 12″ Super Air Knife resulting in a 47 day ROI or where a customer replaced 4 open copper tubes with our 1110SS Nano Super Air Nozzle and recurring their expenses in just 38 days. In these instances, we show the calculations in regards to the true cost of ownership and how quickly you can recover capital funds when considering the whole scope of the project.

At EXAIR, we are committed to providing Intelligent Compressed Air® Products that reduce compressed air consumption leading to a more efficient process, as well as increasing operator safety. If you are considering an EXAIR solution for your current process but have questions about price or performance, contact one of our application engineers for assistance.

Flat Super Air Nozzles – Quiet and Forceful and Adjustable

The 2″ Flat Super Air Nozzle is a very powerful yet quiet engineered nozzle.  Operation at 80 PSIG of compressed air pressure yields a strong 1.38 lb. of force, at only 77 dBA of sound level.  Compare this with many of the plastic flat nozzles that blow air through a series of holes, with sound levels ranging form 78-83 dBA, not to mention some might violate the OSHA dead ended pressure standard and results in fines being levied.

The patented technology utilizes a changeable shim to generate the high flow of air in a smooth and laminar flow, to keep noise down and power and strength up. With (6) stainless steel shim thicknesses available, the 2″ Flat Super Air Nozzle offers a very flexible package that can be set and tuned to meet exacting performance criteria, while using the minimum amount of compressed air, and at the quietest possible sound levels.

2 Inch Flat
2″ Flat Super Air Nozzle

The model 1122 is offered in a zinc aluminum alloy body and cap, and the 1122SS is constructed from type 316 stainless steel.  All shims are stainless steel. The shim thickness for the 1122/1122SS is 0.015″ thick.

Also available, for extra blowing force, are the HP1125 and HP1125SS.  The nozzles utilize the same zinc aluminum alloy or stainless steel body and cap and have the 0.025″ shim installed – and deliver 2.2 lbs of force, while only increasing sound levels to 83 dBA.

Shim sets for any of the 2″ Flat Super Air Nozzles are available.  The 1132SS shim set includes shims of thickness of 0.005″, 0.10″, and 0.020″.  For higher force levels, the HP1132SS shim set includes the 0.020″ and 0.030″ shims.

1132ss
Shims are available, from 0.005″ up to 0.030″ for maximum versatility and performance tuning

As you can see- for a versatile, forceful and quiet engineered air nozzle, it is hard to beat the EXAIR 2″ Flat Super Air Nozzle.  If a 1″ wide nozzle better suits your needs, the same flexibility and power can be found in the 1″ Flat Super Air Nozzle as well.  Check it out as well.

If you would like to talk about Flat Super Air Nozzles or any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

Ion Air Jets Make Beekeeper’s Operation As Sweet As Honey

A honey producer sells their product in specialty glass jars. They pay a premium for these jars, as they enhance the appearance of their product, so the “visual” is obviously very important to them. So much so, that they’re willing to go to great lengths to make sure that the jars are sparkly clean and pristine before filling them with honey.

It’s a given that the inside needs to be clean…it’s a food product, so, of course, there’s a thorough cleaning process for that. The outsides of the jars, though, would sometimes have a little dust or debris left over in the ‘nooks and crannies’ which took away from the crystal clear appearance of the rest of the jar.

They got a Model 8494 GEN4 Ion Air Jet Kit, which they use to remove all of this dust & debris from the outside of the bottle, and then they got another Model 8194 GEN4 Ion Air Jet (which uses the same Power Supply, Filter Separator, and Pressure Regulator from the 8494 Kit) to blow an “insurance” blast of ionized air inside the bottle…just in case. “You can’t be too careful” is a popular mantra for folks who make food products, it seems!

Compact, convenient, easy to use: EXAIR Model 8194 GEN4 Ion Air Jet creates a focused blast of ionized air for static dissipation and cleaning.

Ionized air is extremely effective for ensuring the cleanliness of glass surfaces. Window makers love our Super Ion Air Knives. Some big name sunglasses manufacturers use our Ion Air Jets to ensure the highest quality and consistency of their products. Ion Air Jets and Ion Air Cannons are commonly used to keep optics clean & clear in critical vision inspection systems. If you’d like to find out more about improving “visuals” with ionized air, give me a call.

The Super Air Knife is the latest generation of the EXAIR engineered air knives with dramatically reduced compressed air usage and noise compared to other types of blowoffs.  The Super Air Knife is truly a more efficient tool for cleaning, drying or cooling parts, webs, or conveyors.  The air flow is a uniform sheet of laminar air across the entire length with a hard-hitting force.

Replacing a noisy blowoff with a Super Air Knife results is a significant reduction in sound.  Operation at a high pressure of 80 PSIG (5.5 Bar) leads to a sound level of just 69 dBA for most applications. Air amplification ratios (entrained air to compressed air) of 40:1 is produced. It also meets OSHA maximum dead-end pressure and noise requirements, for safe operation in the vicinity of plant personnel.

Typical applications for use include-

  • Post wash part drying
  • Sheet cleaning in strip mills
  • Conveyor cleaning
  • Part or component cooling
  • Web drying or cleaning
  • Environmental separation (air curtain)

Super Air Amplifiers – Adjustability for Blowoff, Drying, Cooling, Circulation and Ventilation

The Super Air Amplifier is a powerful, efficient, and quiet air mover. Applications currently in place include blowoff, drying, cooling, circulation and ventilation. Sizes from 3/4″ to 8″ are available to best match the air volume that is necessary to achieve the process goals. There are a couple of ways to change the performance of the Super Air Amplifier if either a small or large change to the output flow is required.AirAmplifiers

The chart below shows the Total Output Flow for each of the 6 models. As an example, the Model 120021 or 121021, when operated at 60 PSIG of compressed air supply, will have a total output flow of 120 SCFM. These same devices when operated at 80 PSIG will have a total flow of 146 SCFM. By simply using a pressure regulation device on the compressed air supply, the output performance can be tuned to match the desired outcome.

Capture

For those applications where much greater flow and/or force is needed, the option of installing a thicker shim is available.  The Super Air Amplifiers are supplied with a 0.003″ shim installed (the 8″ model 120028, has a 0.009″ shim as standard) and can be fitted with shims of thicknesses of 0.006″ or 0.009″ (the 8″ model has an optional 0.015″ shim.) Installation of a thicker shim increases the slotted air gap, allowing for a greater amount of controlled air flow.  As a general rule, doubling the shim thickness will double the air flow rates.

Super Air Amplifier Shims
Patented* Shim Design for Super Air Amplifiers

The Super Air Amplifier design provides for a constant, high velocity outlet flow across the entire cross sectional area,.  The balanced outlet flow minimizes wind shear to produce sound levels that are typically three times quieter than other air movers. By regulating the compressed air supply pressure and use of the optional shims, adjustability and flexibility of the unit is wide ranging and sure to meet your process needs.

Super Air Knives Remove Water from Knee Replacement Parts

EXAIR’s Super Air Knives are the go to when you need to dry your parts as they’re traveling along a conveyor. The high velocity, laminar airflow from the Super Air Knife does a fantastic job of stripping away moisture, leaving your part dry for the next stage of the process. With models available in both 303 & 316 Stainless Steel, Aluminum, and polyvinylidene fluoride and at lengths ranging from 3″-108″, there’s a knife for every application.

I was recently working with a customer that manufactures knee replacement devices. He was designing a new blowoff station to eliminate having to have operators manually dry the parts after a washing operation. He created a test rig to test out his theory of using Super Air Knives. While conducting his tests, he was having issues completely removing the water from the parts. Due to some of the grooves and pockets, the underside was not drying in one pass. This led to him having to manually blow the parts off after they exited the basket. This would not be acceptable as the purpose was to remove the operator from this part of the process. After taking a look at some photos of the setup, I noticed that he had the knives angled so that the airflow was blowing perpendicular to the parts. In doing this, the amount of time that the part is exposed to the airflow is greatly reduced. In any blowoff application, maximizing the time & contact that the part has with the airflow is critical in maximizing effectiveness. By angling the knives so that the parts were exposed to the airstream just as they exited washing, he was effectively able to dry the parts in one pass.
