Why Do We Guarantee?

Published on by Al WooffittLeave a comment

We hear about all kinds of applications when working with customers. For many of them, there is an obvious solution. Your electrical panel is overheating – an EXAIR Cabinet Cooler is what you are looking for. If you’re experiencing static on an assembly line – a Gen4 static elimination product is what you need. If you’re trying to blowoff excess water from an extruded pipe, then a Super Air Wipe is the right solution.

There are many applications however, where the solution isn’t as obvious. We know that our products can help, but with the sheer number of variables there isn’t a way to plug everything into a formula and say that this will be the outcome. The end result needs to be found through testing. This is where EXAIR’s 30-day unconditional guarantee comes in. All of our stock, catalog products come with this guarantee. After purchasing one of these products, you have a month to put it through its paces; adjust the angle, adjust the operating pressure, swap out shims. If you are able to find the right conditions to solve your problem, then great! If not, we’ll take it back and issue full credit! You’re only responsible for the shipping to get it back to us.

Line Vac test

A popular application where testing is essential is with our Line Vacs. There are multiple variables at play: the bulk density of the material, the size of the material, is it abrasive?, the rate of conveyance desired, the distance needed to convey – both vertical and horizontal. We’re pretty good at getting you in the ballpark of which model will work best using the data we’ve found from our controlled in-house testing. But ultimately, to know exactly how our Line Vac will perform with your material, it needs to be hooked up. When you purchase from us, you have 30 days to do that risk-free.

At EXAIR, we want to ensure you are getting the best possible solution. Our 30-day unconditional guarantee is one way that we make that a reality. If you would like to discuss how our products can help with your application, give us a call!

Spring Cleaning: Cleaning your RDV and Chip Trapper

Published on by Al WooffittLeave a comment

Whenever spring rolls around, spring-cleaning comes to mind. It’s the time of year that we are reminded, or perhaps motivated, to start cleaning and de-cluttering. We experience this here at EXAIR with an increase in inquiries about our Industrial Housekeeping Products. We have a great line of drum vacs designed for use with dry materials (Chip Vac and Heavy Duty Dry Vacs) or liquids (Reversible Drum Vacs – RDVs, and Chip Trappers), or both (EasySwitch Wet-Dry Vac). What we don’t often think about are cleaning or maintenance routines for our cleaning products.

As long as you supply our intelligent compressed air-operated products with clean, moisture-free compressed air, they can run near indefinitely with little to no maintenance. Due to the nature of the kinds of jobs drum vacs are being used in, even with the cleanest compressed air systems, there is some need for preventative maintenance to keep them working like new. In this blog I review some basic cleaning routines to keep your RDV or Chip Trapper working as new:

  • Ensure you are supplying enough compressed air. We recommend 80-100psig. This will consume at least 19scfm. If your supply line is too long, or too small in diameter, you will suffer line loss. This will lead to poor performance. It is also important to avoid any restrictive fittings like quick connects.
  • Ensure there are no vacuum leaks. A loose vacuum hose, leaky hose cuff or a loose fitting drum adapter will prevent the pump from being able to evacuate enough air from the drum. Even small hairline cracks in the drum can allow air in and cause vacuum performance to suffer. A visual inspection of these areas is a great first step. We stock all replacement parts if you need to replace a gasket, or quick connect fitting.
  • Ensure your compressed air supply is clean. The tight passages in the venturi chamber can become contaminated, limiting the RDVs’ ability to draw a vacuum. We recommend the use of a 5-micron automatic drain filter (EXAIR Model 9001) to prevent this. If the RDV has become dirty inside, it is relatively straight forward to clean it. This video takes you through the steps.
  • Ensure the safety shutoff valve float is moving freely. The plastic float provides overflow protection. It will rise when the drum is full, which will break the vacuum. If the float becomes stuck, it will impede vacuum performance. Cleaning out this chamber and the float, allowing it to move freely will ensure that RDV can function properly.
  • Finally, for Chip Trappers, ensuring that the directional valve is clean and clear of chips. With frequent use or when filtering out long stringy chips, the liquid flow passageways of the EXAIR Chip Trapper may become blocked with swarf. The following video walks you through cleaning this valve:

All of these steps will keep your RDV and Chip Trapper running like new. If you would like to learn more about our other Industrial Housekeeping Products, feel free to give us a call!

Using the EXAIR EFC

Published on by Al WooffittLeave a comment

We like to tout the benefits of our intelligent and efficient compressed air products. For example, our Super Air Knife entrains ambient air at a ratio of 40:1, so for a moderate amount of compressed air, you will get large volumes of air blowing against your part. But another way you can be efficient is by turning your compressed air off – or at least only turning it on when you need it. For example, if you are drying parts moving along a conveyor, turning the air off in between parts will save even more compressed air. You only need to use the air when it is necessary. This is where EXAIR’s Electronic Flow Controller, or EFC, comes in.

Our EFC is great for automating processes involving compressed air use, by turning the air flow off when it’s not needed.  In fact, not only does it provide simple on/off control to blow only when a part is “seen” by the photoelectric sensor, there are eight distinct modes to incorporate delay on or off, flicker on or off, signal on/off delay, interval, or “One-Shot,” where the sensor detects the part, delays opening the valve per the timer setting, and blows for one second. The different modes are demonstrated in this video:

We include the EFC with our Deluxe Super Air Knife Kits for the obvious synergy with the Super Air Knives’ typical applications of cooling, drying and cleaning. However, there are many other EXAIR products and applications that could benefit from the functionality of the photoelectric sensor. Take our Line Vacs, for example. If a hopper is being filled with product that is being conveyed by the Line Vac, you can use the sensor on the EFC to turn off the Line Vac. Alternatively, you could use the sensor to detect when the hopper is almost empty and turn the Line Vac on.

We have had customers use our EFC to control the flow from our Atomizing Spray Nozzles. When the sensor detects the parts being coated, the EFC turns on the compressed air supply, allowing the Air Atomizing Spray Nozzle to apply a coating. Once the part has been coated, the EFC shuts off the air supply, not only saving on compressed air, but also the liquid used to coat its parts.

Our Electronic Flow Controls can accommodate flows up to 350scfm, so they can be used in a wide variety of applications. In fact, the more air volume you control with one of these, the faster you can amass savings and the faster your return on investment! If you would like to discuss how an EFC could save you money, give me a call!
