Clearing the Air in Arkansas: Owner Turns to Miller to Improve Air Quality with FILTAIR® Fume Extraction

The owner/operator of Chandler Equipment knows what it’s like to work as a welder. It’s his experience under the hood that led him to install a FILTAIR centralized fume extraction system in his shop. 

 The process for change at Chandler® Equipment always begins with a well-thought-out plan that includes thorough investigation. No piece of equipment or building change occurs without good reason and a bulletproof strategy. Adding fume extraction to the building was no different. After two years of evaluations, sales pitches and careful thought, Jeff Chandler and his crew chose the FILTAIR system from Miller to protect employees and his investment.

 

Supplying oil and gas

 

Chandler Equipment started out as a farm equipment business 30 years ago. The company then expanded into industrial-type waste-hauling tanks. Today the company manufactures hatches and ports for tank vessels in its Springdale, Ark., plant. The company supplies large oil and gas companies with the parts they need for their waste tanks used in the oil fields during America’s current oil and gas boom. Chandler fabricates the accessories for the tanks. Tank hatches, valving and the fittings for the tanks are the company’s sweet spot.

 

Chandler takes raw metal and fabricates the needed part. The majority of the work is done in his eight welding automation cells, while ten manual cells remain for smaller custom jobs or ones that take the expertise of a seasoned operator when the repetitive nature of automated welding won’t work.

 

“We started out with Miller® welders in the beginning, and throughout the years we’ve evolved with all the different types of power sources,” says owner/operator Jeff Chandler. “From the welding machines with an operator, all the way on up to what’s available now — with the automated welding cells and the computerized processes in welding.”

 

The material used ranges in size from 14-gauge up to ½-inch, with anything from short-circuit to spray-transfer welding. On both the manual and automated side of the Chandler welding business, the vast majority of work — 80 to 90 percent — is working with mild steel. However, as aluminum and stainless steel became a growing presence in the shop, the need to rid the building of fume and smoke became even more critical. 


 

Cleaning the air

 

Jeff Chandler got his start in the family business as a welder years ago. Today he runs the company, but remaining sharp in his mind is that past daily grind of welding fume and dust particles he experienced on the job. He wanted to give his employees the highest quality of filtration available. It started out as a combination of exhaust and ventilation fans. It did not take long to realize fans would not accomplish the high standards he had set for his shop in the manual welding area, along with his eight automated welding cells. 

 

“We’d been using ventilation fans and exhaust fans over a period of time,” says Chandler. “It just didn’t work. There was always a cloud around during the workday. And in the winter the cold air we brought in through the ventilation meant we were spending a fortune trying to heat the place. We needed to do better to clean the air.”

 

Chandler’s first priority was the ten manual welding cells where the weld fume came in direct contact with his employees. He contacted Steve Jones from Airgas Mid South in Springdale for answers. Jones offered up the FILTAIR SWX wall mounted dual-arm system from Miller.

 

“Jeff started out with the purchase of the two dual-arm wall mount systems for the operators in those stations and was very happy, very satisfied,” says Jones, account manager with Airgas Mid South. “The two systems were working out so well for them, the shop started cleaning up immediately. Jeff gave us a purchase order for three additional units.”

 

While the success in the manual welding cell was phenomenal, there remained a haze in the larger automated portion of the facility. The eight automated cells were dutifully carrying out the welding programed into the electronic memory banks. The resulting weld fume was not acceptable to Chandler.

 

“Once Jeff made the decision that they needed to continue to move forward pulling the welding fumes out of their shop, they sat down and started researching the automated side of their business,” says Jones.


Chandler complemented the FILTAIR fume extraction systems for its manual weld cells with specific hoods and a centralized collection point for its automated applications, as well.

The FILTAIR centralized system

 

One of the three finalists was the FILTAIR centralized system from Miller Electric Mfg. Co. The system, designed by welders, was created specifically to capture weld fume. The group was familiar with the FILTAIR SWX series fume extractors from Miller and how well they worked. The centralized system moved to the top of the list because the group was familiar with Miller and the high standards for quality and toughness in products.

 

“When we came across Miller and the FILTAIR system, we found that everything was pretty much confined to the robot, and the particles could be taken off right exactly when it was welded,” says Chandler. “When I found out the footprint of the machines was 65 percent smaller than the average centralized collector, we took an even closer look.”

 

What Chandler and his team found was not only a compact package, but also one with the power needed in an industrial setting. The compact size allowed for indoor setup and the clamp ducting system meant no expensive tear outs if the company decided to expand and add more automation or cells.      

 

“Miller came up with a way of figuring it all out for us. They were turnkey, so we didn’t have to worry about our configuration; they matched what we had,” says Chandler. “Miller planned everything for us, and we didn’t have to worry about anything except for getting electric installed. Everything just fit right — really simple.”

 

Change in the air

 

The effect on the atmosphere at Chandler was immediate. Within a few hours of flipping the switch on the newly installed FILTAIR centralized system, the building cleared and the air quality drastically improved. Gone was the smoky haze hanging above the manufacturing floor.

 

“I was amazed. The clean air, it was just like it cleared up in a second,” says Moore. 

 

It inspired Chandler to spend a day cleaning the entire facility from the factory floor to the rafters above. A cleansing that remains today, thanks to the FILTAIR systems quietly hard at work.

 

“We cleaned the whole building, all the beams throughout, so everything would stay clean from now on — so we wouldn’t have any weld fume problems or particles in the building,” says Chandler. “I’d want this facility to be how I would want it if I was welding. The wellbeing of my employees is very important.”

 

The system’s footprint is 65 percent smaller than other centralized systems. The FILTAIR is also one of the quietest fume capturing systems on the market. The noise level is so low that Chandler employees can carry on normal conversations while right next to the hard-working machines. 

 

“You can just barely hear it. You can talk being up next to it. That’s very important, especially when you’re giving instructions on things that need to be done,” says Moore.

 

The maintenance of the system has been a breeze, according to shop foreman Moore. At a Minimal Efficiency Rating Value (MERV) rating of 15, the FILTAIR is efficient at removing 99 percent of weld fume. But thanks to the Linear Jet Automatic Cleaning System, the particle surface loading FilTek™ filters remain efficient at capturing weld fume longer than other filters. When it does become time for maintenance, the filters’ surface-loading capture of fume particles allows for easy cleaning. 

 

“With the centralized system, the benefits are a lot less maintenance, a lot less cleaning for our part. It does it all itself,” says Moore. “It’s user-friendly.”


Source capture proved more effective for the manual weld cells at Chandler than ambient exhaust and ventilation fans, helping improve operator comfort and safety.

Adjustable in a click

 

Unlike some of the more rigid systems, which require traditional ductwork that would need to be torn out if expansion were necessary, the FILTAIR system was installed with a unique snap-tight interlocking ductwork system. When assembled, the design ensures a sealed system that can also be easily changed as the business grows. New cells can added without tearing out the system.     

 

“In fact, the duct work is a whole lot smaller than a lot of the other people bid out. We were bidding out some huge duct work and I didn’t know how we were even going to put it in this building,” says company owner Jeff Chandler. “The adjustable part is absolutely important. For future use we’ll be able to expand in areas and add on when we need to. Everything is flexible where we can hook right on to it or ‘T into’ the group that’s existing today. No other system could offer that feature.”

 

Reduced energy consumption

 

One surprise with the installation of the FILTAIR system was the consistent temperature of the building. Before, when pulling cool or hot air from the outside, the thermostat would spike one way or the other. Today the centralized system provides a consistent environment that has kept the thermostat and the resulting heating or cooling bill in check.

 

“We always had a problem with the flow of air because different days the air outside was different,” says Moore. “Now we’re not even turning the heat on in here, and the system itself is keeping it warmer and we’ve lowered our heating bill. With it taking the fume out of the air, we do not have to clean as much as we used to.”

 

“After using the FILTAIR systems, now everything is just so pure, it’s unbelievable, air-quality-wise,” says Chandler. “The employees are all a lot happier.”

 

Partnership clears the air

 

It makes Chandler smile knowing his desire to clear the air has had such an immediate and beneficial impact on morale. He’s been a longtime supporter of Miller equipment and his friends at Airgas — and it’s more than just the great products.

 

“Miller has done the research and instills the quality that needs to be in a product before they give it to a customer,” says Chandler. “Whether it’s a welding machine or FILTAIR system, they make the best and they want the customer to be satisfied. That means my repeat business. We work hard with our customers to create repeat business and customer service. That’s why Miller is such a good partner — we’re more than an order number.”

 

Jeff Chandler now has peace of mind that his employees are receiving the best fume extraction available — and that his partners will be there the next time he decides to make a well-thought-out and vetted improvement.
