Do You Need 30 Days for Testing?

Published on by Leave a comment

Not long ago while checking out of a motel my laptop bag that was attached to the handle on my suitcase fell forward and the impact shattered the screen on the laptop.  Upon turning the computer on I realized that a new screen was in order.

I waited until I arrived at home and found what I thought to be the correct monitor and quickly ordered it.  It arrived two days later and I painstakingly took the laptop apart and exposed the mounting frame.  The removal of the broken screen and the installation of the new was not too difficult but the cable connector was less than robust and was very tight.  Carefully I worked it back and forth and it came free.

Installation and reassembly went quickly and then I powered up the machine.  I was only greeted with a series of very loud and annoying beeps.  At that point I shut it down and called the company I purchased the screen from and described the issue.  They determined that the resolution of the screen was incorrect for my laptop and that I needed a different model.  They said I could return the incorrect one and upon inspection receive a credit less the return shipping.  At that point I ordered the correct screen and packaged up the wrong one and dropped it off at the parcel delivery service.

The new model arrived and it installed easily and worked perfectly.  I waited patiently and never did see a refund so I called the company and they said that it was an oversight on their end and that it would be corrected within 48 hours.  Sure enough they issued the credit and money was credited back to my account with one exception, the 40% restocking fee!

I can tell you that EXAIR is not that way!  If you order the wrong item or are not satisfied for any reason and the item was purchased within the last 30 days we will facilitate the return and ZERO restocking fee. There are a multitude of reasons our customers would want to take advantage of our 30 day guarantee and we make it a simple transaction if you need to take advantage of it too. Testing is one reason a customer would use this 30 days, other customers may have ordered incorrectly or released product inadvertently, they may have wanted a small sample for a meeting or demonstration at a customers location.

Need to Cool Tooling but Limited On Compressed Air? Consider the Mini Cooler

Published on by exaircorpLeave a comment

I recently had a chat conversation with a customer who was looking to cool the tooling on his CNC router, mill and lathe in his small machine shop. During the machining process, as the tooling would begin to heat up, it would warp the bit, causing irregularities in the finished product. In some cases the tooling was getting so hot, it would actually break, creating a safety concern.

He had reviewed some of our cooling products and was thinking of using our Cold Gun in the application but was concerned with the air demand. The Cold Gun consumes 15 SCFM @ 100 PSIG and provides a 50°F temperature drop (from supply temperature) with 1,000 Btu/hr. of cooling capacity. The problem was that his compressor only produces a little over 9 SCFM. I explained that the existing compressor would in fact be undersized as it doesn’t produce enough volume to keep up with the demand of the Cold Gun.

Model 3808 Mini Cooler System with Single Point Hose Kit, includes swivel magnetic base and filter separator to remove moisture and particulate from the air supply.

Due to the limited amount of compressed air available, our Mini Cooler System, Model # 3808, would be the better solution. The Mini Cooler also provides a 50°F temperature drop with a little less cooling power, 550 Btu/hr., but this system only requires 8 SCFM @ 100 PSIG, falling within the existing compressor’s output capacity. The Mini Cooler also includes a magnetic base as well as flexible tubing to direct the cold air to the desired location, making it easy to move from machine to machine.

The Mini Cooler is the ideal solution for small tool or part cooling, with minimal air consumption.

If you are considering an EXAIR product for an application or have additional questions about performance, contact an application engineer for assistance in making the best selection.

Simplifying Plastics Machining Using The Cold Gun And Chip Vac

Published on by exaircorpLeave a comment

I was recently contacted by a plastics manufacturer who was needing some solutions for problem areas in their production processes. The company imports their machines from overseas and they are outfitted with a coolant based, quench system for the tooling. They were wanting to get away from using coolant as the parts were absorbing liquid, causing them to swell, not to mention the mess they were creating, requiring more time and labor to dry and clean the parts manually.

For the first application, replacing the messy misting system, I recommended the customer use our Cold Gun System, Model # 5215. The Cold Gun uses Vortex Tube technology to produce a cold air stream 50°F lower than the incoming compressed air supply temperature. For example, if your supply air was ambient 70°F, you would effectively see 20°F air at the exhaust. This clean, cold air stream can be easily directed to the needed area to prevent any warping or other damage related to heat, while also blowing away the machined fines.

Model # 5215 – includes the Cold Gun, Single Point Hose Kit, 3/8″ Cone Nozzle, 1-1/4″ Fan Nozzle and Filter Separator

The second part of the process involved the recovery of the plastic scrap and chips created during the machining process. Once again, EXAIR has the ideal solution with our Chip Vac, Industrial Vacuum. The Chip Vac creates a powerful vacuum, with no moving parts or motors to wear out, making them virtually maintenance free. The Chip Vac is designed to vacuum dry or wet chips and collect them in a standard, open-top steel drum. Systems are available in 5, 30, 55 or 110 gallon capacities.

From small area clean up to larger scale processes, the Chip Vac has you covered

Now through the end of 2017 if you purchase a Single-Point Cold Gun Kit with Model W5215 for the standard Cold Gun or W5230 for the High Power Cold Gun, we’ll include a free Model 5902 Dual Point Hose Kit, a $35.00 value!!

EXAIR’s Cold Gun was a Product of the Year finalist in 2007. By using only a source of compressed air, the Cold Gun and High Power Cold Gun produces a stream of clean, cold air 50° (28°C) below your compressed air supply temperature. The Cold Gun is very quiet at only 70dBA and has no moving parts to wear out. Just supply it with clean, dry compressed air and its maintenance free!

The Cold Gun is pre-set to an 80% Cold Fraction. In other words, 80% of the compressed air supplied to it will exhaust from the cold end of the tube, 20% from the hot end. This prevents the Cold Gun from freezing up during use and optimizes the gun’s cooling capacity. The Cold Gun is an ideal alternative to messy and expensive coolant mist systems. It eliminates the cost of purchase and disposal of cutting fluids as well as worker related health problems from breathing airborne coolant or slipping on wet floors. Replacing a coolant based system also eliminates the need for secondary cleaning operations after milling or drilling.

The Cold Gun is an invaluable tool for machining a wide range of plastics and other materials that may become contaminated when using traditional coolants or oils. The clean, cold air from the outlet of the Cold Gun keeps the part cool, clean, and dry. Take for example this application where an OEM for the plastics industry uses EXAIR Cold Guns in place of a coolant system.
