Established Fume Removal and Fabrication Experts

Both Monoxivent and Crawford Company have been in business since the 1950's. Strong belief in company ideals and principals, hard work, and dedication to excellence have seen both companies grow from humble beginnings to nationwide status. Monoxivent Source Capture Systems and Fiberglass Reinforced Plastics are installed throughout the United States, Canada, and industrialized world. Crawford Company proudly serves the Quad Cities and surrounding areas as a full service HVAC, Plumbing, and Electrical company, but has also established themselves as a powerhouse in custom steel fabrication. It's the unique strengths of both companies that make Engineered Stacks a brand that you can trust for high quality, American made solutions.

Monoxivent Source Capture Systems

Monoxivent is guided today, as it has been for over 70 years, by Monoxivent’s original values: a commitment to product quality, customer service, innovation, business integrity, and a high regard for individual contributions. Monoxivent, founded in 1953, has grown from a small shop to a thriving corporation that looks to carry its momentum into the years ahead. The company, which specializes in source capture systems and products, competes with the nation’s elite in regard to vehicle and fume exhaust solutions.

The “Monoxivent brand” originated under the KENT-MORE corporate umbrella in Detroit, MI. In the early days, the company promoted “getting rid of exhaust fumes, without wasting heat!” A selling point that holds true in the 21st Century. Health, safety, and efficiency were also big selling points in the 1950’s, as they are today.

The Monoxivent Jr. was an early top seller and was targeted towards gasoline service stations. The system offered an inexpensive, yet practical method of eliminating fumes. A version of this is offered today with high-temperature hose and door ports.

Underfloor systems were also very popular from the outset. Neoprene, stainless steel, and galvanized tubing were all popular options, especially in the 1960’s and 1970’s.

Acquisition by Crawford Company

The company moved to Moline, IL/Rock Island, IL (Quad Cities), in the 1980’s. John Sandberg and Drake DeVore grew the business throughout the nation in the 1980’s and through the 1990’s. DeVore added “DSP” to the corporate name in the 1990’s. Today the company is referred to as Monoxivent once again.

Crawford Co. then purchased Monoxivent in 2000 and brought the company into its corporate mix.

Crawford Company Fabrication
