Accessories for Your Compressed Air Products

Published on by Al WooffittLeave a comment

Here at EXAIR we are very proud of our Intelligent Compressed Air Products. We have spent a lot of time discussing their many benefits, including their efficiency, the fact that many have no moving parts, little to no maintenance, meeting or exceeding OSHA safety standards for noise or dead end pressure. One thing we don’t talk as much about is the accessories that go along with and complement our products. Several of these accessory items are the reason why our compressed air products can boast about having little to no maintenance, or reduced noise levels. In this blog I want to cover some of these unsung heroes.

From left to right, a few value-added accessories for your Vortex Tube: Hot Muffler, Cold Muffler, Automatic Drain Filter Separator, Oil Removal Filter, and Solenoid Valve/Thermostat Kit.

Some of the most popular accessories we offer are our compressed air Filters and Regulators. We suggest using these with all our products (or even with ones that aren’t ours).

The Filter Separator is designed to remove moisture, dirt, and rust from your compressed air system. The 5-micron filter element ensures that contaminants don’t clog or harm your compressed air equipment.

An Oil Removal Filter (which should always be installed after our Filter Separator) provides even more precise filtration by getting rid of oil and solid particles with a 0.03-micron element.

Our Pressure Regulators let you choose the operating pressure. At EXAIR, we always advise running at the lowest pressure necessary to complete the task. Pressure Regulators help you achieve that, reducing unnecessary air usage and fine-tuning the performance of EXAIR products for your specific application.

We have some accessories designed specifically for certain products. For our Line Vacs, there’s the Line Vac Hose. You can also find Thermostats and Solenoid Valves that work great with our Cabinet Coolers, and if you’re using Vortex Tubes, we suggest checking out our Mufflers.

When it comes to our Air Knives, we offer a variety of fantastic options:

If you’re looking for a simple and dependable way to mount your Air Knife, our Universal Air Knife Mounting System is just what you need.

If your project needs something longer than our stock Air Knives, or if you want to manage different sections of the air flow separately, our Coupling Bracket Kits are ideal.

And if you want to simplify the plumbing for your Air Knife, don’t miss our Air Knife Plumbing Kits. They’re suitable for all Air Knives that are longer than 24 inches.

If you’re looking for plumbing options, we’ve got a range of compressed air hoses and fittings that will simplify things for you.

Our Coiled Hoses work great with our Safety Air Guns, giving you more freedom of movement while you work.

Our Compressed Air Hoses are often used alongside our Industrial Housekeeping products to provide the necessary reach for the drum and dolly.

Finally, if you’re looking for a way to mount or position your Air Nozzles, check out our Magnetic Bases, Stay Set Hoses, and Swivel Fittings that can help create a complete setup.

No matter what your application requires or the product you need, we’ve got a variety of complementary accessory products that will simplify installation and adjustments. If you have any questions about these or any other EXAIR products, don’t hesitate to reach out to us.

BETE’s Foam-Busting Nozzles: Spraying Suds into Submission with Industrial Swagger

Published on by Jordan T ShouseLeave a comment

When I hear foam, the first thing that comes to mind is my salt water fish tank and the protein skimmer below it doing the dirty work of pulling all the fish waste from the water colum. In this case, the foam is good. It operates on the principle of air-water interaction and the hydrophobic nature of organic compounds. Air is pushed into the water, creating tiny bubbles. All those tiny bubbles provide a large surface area for the organic molecules to adhere to them. The bubbles rise to the top with those molecules and are collected into a cup at the top of the skimmer. Check out the photo below.

Saltwater Skimmer

This is a purpose-built foam generating process that is a huge benefit for every saltwater reef tank.

However, the same thing can happen during industrial processes and, in most cases, becomes a problem to fix rather than a benefit. Foam is undesirable because it can overflow vessels, create slippery and unsafe working conditions, interfere with processing, damage materials, and cause tanks to drain and dry slowly. Controlling foam can be accomplished by spraying liquid onto the pool, vessel, or reservoir’s surface, and allowing the spray’s droplets to impact the foam bubbles, causing them to break.

While breaking this foam sounds easy, “Just spray some water on it” in the process, it can be a challenge to get the correct size of droplets to break the foam. Droplets that are too small often cannot pop the bubbles, and if the droplets are too large they can break through them and create more agitation which creates more foam. You want a sweet spot where they are large enough to pop the foam bubbles while small enough to not create more foam.

Here is a real customer case, where BETE Application Engineers were able to assist the customer with an array of MaxiPass nozzles to knock foam down in a wastewater tank.

Industry: Petroleum Processing
Application: Foam Control
Product Description: MP Nozzle Array

Situation: A customer had processed condensate wastewater in a petroleum processing facility. The wastewater was in a square tank that measured 10’ x 11’ by 9’ (3 m x 3.4 m x 2.7 m) deep.
As the wastewater entered the tank, foam was generated, which was undesirable in this process. The customer had about 25 gpm (94.6 L/min) available to use to control the foam. In
In addition, the customer was looking for a turnkey system that could be installed as soon as it
arrived on site.

BETE’s solution: BETE Applications Engineers first determined that a 3 x 3 array of BETE
MP187M nozzles operating at 10 PSI (0.69 bar) would give the desired flow of 25 gpm total and
knock down the foam that was being generated. The next step was to review the customer’s piping
specifications in order to come up with both a nozzle header design and a feed header design.
Using one feed header and three nozzle headers, the customer simply had to bolt and gasket the
flanges, hook the inlet up to a water source, and they will be ready to go!

Whether you’re looking to optimize your industrial processes, improve efficiency, or tackle specific application challenges, the right liquid nozzle or compressed air product can make all the difference. EXAIR and BETE offer industry-leading solutions designed to meet your unique needs with precision and reliability. From air-atomizing nozzles to liquid-only nozzles, our innovative products deliver top performance across a wide range of industries. Ready to take your operations to the next level?

Application Spotlight! – BETE TurboMix Eductor Mixing Nozzles

Published on by Jordan T ShouseLeave a comment

Application Spotlights have been something I’ve been doing for the better part of a year now. In these sessions, I draw from numerous phone calls and emails to guide you through the process our Application Engineering team uses to choose a product for a particular application! Today is especially exciting, as it features a BETE product, the 3/4TM150@7, ¾” MNPT, 316 ST.ST TurboMix.

The customer had a tank measuring 9 feet in diameter and 22 feet in height, containing approximately 10,000 gallons of water with suspended metal solids. They were relying on a 270 GPM inflow and outflow to generate sufficient movement to maintain the suspension of the metal solids. However, this method proved inadequate for achieving complete and proper mixing within the tank, prompting them to reach out to us. This scenario is a well-established application for the BETE TurboMix nozzles. Let’s jump into the technical side to see what we specified for this application.

To agitate liquids with suspended solids, we want to position the TurboMix at the bottom of one side of the tank and direct the plume upward toward the opposite side of the tank, aiming at the highest liquid level. To sweep solids along the tank bottom, direct the TurboMix plume upward at a 10º angle, using enough units to cover the bottom surface completely. (See the photo below) For some applications, directing the plume toward the pump inlet is useful.

We usually calculate based on turnover per hour. 3 or so is typical for general circulation; 5-6 is often more typical of blending operations. Being they wanted to have the ability to turn the mixing on and off, we calculated for the middle of the road at 5 times per hour, so the total required flow for mixing would be 872.5 GPM. Based on that, we recommend eight of our 3/4TM150@7, ¾” MNPT, 316 ST.ST. TurboMix Eductors.  Four on the 0-10* side of the half-moon and four on the 45-80* side.

At 30 PSI, each nozzle will be flowing 25.7 GPM, meaning the design pump flow required would be 205.9 GPM.  The design pump flow does not take into account the plumbing.

Whether you’re looking to optimize your industrial processes, improve efficiency, or tackle specific application challenges, the right liquid nozzle or compressed air product can make all the difference. EXAIR and BETE offer industry-leading solutions designed to meet your unique needs with precision and reliability. From atomizing nozzles to air amplifiers, their innovative products deliver top performance across a wide range of industries. Ready to take your operations to the next level?
