Industrial Dust Collectors & Industrial Air Cleaners

Any manufacturer of dust collectors and air pollution control equipment can give you clean air, but at Sly Inc, that’s just the beginning.

Sly, Inc. produces a wide-ranging line of reliable, strong baghouses, industrial dust collectors and industrial air cleaners and more that will keep your company running clean and efficient. Sly baghouse dust collectors have been used in many applications and industries for over 100 years, and Sly even holds the very first patent ever issued for cloth type dust collectors.

Unlike many air pollution control equipment suppliers, we refuse to mass-produce product and then hope for a good fit. We have maintained flexibility in our engineering techniques which permit us to manufacture all baghouses and dust collectors to fit the task at hand, while maintaining a price to you that is comparable to mass-produced equipment. In many cases it costs no more to get the very best in dust collection equipment. Please contact Sly, Inc. today, and let us show you peace of mind.

A Little History…

Sly was founded in 1874 as a manufacturer of foundry equipment. The company’s experience with dusty environments lead to its development of dust collection equipment. Sly holds the very first patent for a cloth-type dust collector issued in 1902.

The company has subsequently expanded into three styles of dust collectors:

  • Cartridge
  • Envelope
  • Tubular bag

and three styles of wet scrubbers

  • Impingement baffle plate
  • Venturi
  • Eductor

Why We Are Different
Many companies make air pollution control equipment, but none have been doing it as long as Sly.

Over a century has passed since our original patent for the cloth dust collector. Over the years, we’ve learned plenty about the application and fabrication of dust collectors and scrubbers. Here are the main points:

“In the pollution control business, conservative application of technology is best.”
Equipment misapplication has no place in the air pollution control business. Not only is improper equipment apt to fall short of collection requirements, it is oftentimes more expensive to operate than the proper machinery. For example, incorrect sizing and improper media choice can easily lead to excessive maintenance and costly downtime. When you deal with Sly, we have your best long term air pollution control interests in mind.

“We believe in fitting the equipment to the customer’s needs, not the customer to the equipment’s capabilities.”
This approach earns us the respect and repeat business of many sophisticated buyers of air pollution control equipment. These people, many of whom buy dozens of dust collectors or scrubbers every few years, have always represented a large portion of our customer base.

“We build our own equipment…for some very good reasons.”
Part of the reason Sly can custom-make a dust collector or scrubber for you while keeping a competitive price is just that: we are the manufacturer. Unlike the majority of our competitors, we don’t outsource our dust collection production. We do our own engineering, metal fabrication, painting, assembly, quality control, and laboratory R&D. This way we control every step of the process, allowing us greater flexibility to build the best dust collector or scrubber for your individual needs. We have a strong commitment to shipping dates and routinely guarantee ship dates when requested.

“Our obligation to the customer doesn’t end when the equipment is shipped.”
Sly’s staff engineers can promptly assist you in troubleshooting your dust collector or scrubber or with other field service problems should they arise at your facility. This commitment to total customer support helps guarantee superior value for your investment.

“We’re a private company, and intend to stay that way.”
The corporate restructurings and short term goals of today’s business scene aren’t for us. Sly is owned and operated by descendants of the founding family. We are in the dust collector business for the long run, and will maintain the professionalism and continuity required to contribute to the long term success of your business.
