E-Vac For Vacuum Gluing

February 26, 2009 — ndraker

I’m sure that the technique of using vacuum to assist in holding two items together during a gluing process has been around as long as the materials which could produce an air tight seal (vacuum bag or bladder) have been in existence.  Probably since polymers were first produced in the early 20th century.  Vacuum gluing, as I’ll term it here, seems to be in widespread use in the musical instrument building and furniture building industries.

You may ask, “What does this have to do with EXAIR?” Since EXAIR has been producing our E-Vac vacuum generator products, we have been running into various applications for which we found there was a need to produce a high level of vacuum (say -21″ to -27″ Hg range). The most recent and interesting application for me as a musician was in building guitars.

It is my understanding after speaking to one, that there are quite a lot of custom guitar builders out there who need a way to create force between the bridge and sound board of a guitar to ensure proper gluing between the two components.

The fixture consists of a frame that incorporates an air tight membrane and a port to which a vacuum source can be applied. This is where the E-vac comes into play. Up until now, the vacuum was created by a dedicated, mechanical vacuum pump. But now, the E-Vac can be connected to a small, roll-around compressor to produce the necessary vacuum to suck the membrane down around the bridge and create the needed down-force without clamping the whole instrument body.

My point is that the vacuum gluing process is not new by any means, but how you generate the vacuum could be.  It can also be more economical with our prices starting at just $58.00 US.

So, if your business or hobby involves gluing processes that could benefit from vacuum technology, please take a look at our E-vac vacuum generators or call us. We would be glad to help figure things out for your application.

Line Vac Leaves No Mess

February 25, 2009 — esmortimer

I got a call from a rubber and vinyl tile and flooring manufacturer last week.  They were having problems with the little shavings building up on and around the machines as the tiles were being manufactured, creating quite a mess.  Someone was having to spend time and energy periodically cleaning the area and taking the piles to a collection area. 

The particles were very small, and they only needed to be moved about 3ft over and 8ft up to the collection area.  So, our Model 6080 1″ Aluminum Line Vac was a perfect fit for the job.  The conveying distance is well within the capabilities of the unit, and it will only require minimal demand on their compressed air system.  It will also easily be able to keep up with the rate at which the chips are being generated, preventing any buildup of scrap material.

This will virtually eliminate any extra time for cleanup, and no shavings will pile up, maintaining a clean working area.

Engineered Vs. Ordinary

February 24, 2009 — kaedwards

An air nozzle is an air nozzle, right? If I could write a buzzer sound, a wrong answer sound, I would. Because there are clear and measurable differences between Engineered Air Nozzles and ordinary air nozzles.

Step number three in Six Steps to Optimization is:
1. Measure your air consumption
2. Locate and fix any compressed air leaks in the system
3. Upgrade your end use blow off applications with engineered products
4. Turn off the compressed air when not needed for production
5. Use intermediate storage of compressed air near the point of use
6. Control the pressure at the point of use to minimize consumption

Your ordinary nozzle with a through hole and a cross drilled hole can be an easy choice based upon price, but if you do not consider the operating cost you do not really know how much it is costing you. An Engineered Air Nozzle will pay for itself and lower operating costs quickly. Engineered Air Nozzles are the future of compressed air efficiency and are made to replace ordinary nozzles, homemade nozzles and open line blow offs.

Engineered Nozzles reduce air consumption and noise levels; ordinary nozzles cannot compete. Engineered Nozzles maintain safety features and can qualify for an energy savings rebate from a local uitility; ordinary nozzles fall short. Open blow off or homemade blow off applications typically violate OSHA safety standards; Engineered Nozzles do not.

Engineered air nozzles can produce a larger net gain of efficiency than ordinary nozzles. EXAIR’s product line includes many different models of an Engineered Air Nozzle including our highly efficient Super Air Amplifiers, Super Air Knives and Super Air Nozzles. Each of them, applied properly, have the ability to reduce air consumption, reduce noise levels, increase safety, and reduce compressed air operating costs.

So if you have open blow offs, manifolds with ordinary nozzles, pipes with drilled holes or prefer the lower cost cheap nozzle – find out how much air you are using with these products and look to EXAIR to begin your air savings program.

Vortex Cooling a Variable Speed Motor

February 23, 2009 — japanfalone

It is hard to imagine coming off the coldest spell of the year that I would be presented with a cooling application. In steel mills, paper converters, bakeries, and canning companies, indoor temperatures can be quite high regardless of the outdoor temperatures.

My customer was operating a variable speed motor near an autoclave. The motor was equipped with a fan blade attached to the spindle. At higher RPM’s the fan is able to circulate enough air to keep the motor cooled. But at lower RPM’s, there is insufficient airflow and the motor overheats.

I recommended he build a plenum over the air intake and install a Model 3240 Vortex Tube to feed air into the fan without introducing hot ambient air. The cool dry air from the Vortex Tube not only cooled the motor but it also prevented steam from entering the motor when the autoclave was opened. This in turn eliminated corrosion to the internals parts of the motor.
