Curb Pollution with Exhaust Ductwork & Industrial Ventilation

Toyenco has helped a range of companies since 1974, and continues to do so. Below, you'll find a case history of some of our business consulting projects. Read on to get an idea of the things we can do for you!

Ventilation Duct

Pollution Control - Exhaust Ductwork

Client - A pollution control equipment manufacturer recognized the value of having a technical resource work closely with their customer's people to assist on the installation of a turnkey pollution control system. They needed 50,000 CFM. Our job was to process an exhaust ductwork system to connect four existing web coating lines into two new thermal oxidizing pollution control devices.


Toyenco, Inc. was hired to design and install the system. Our engineers and associates, working closely with our clients and their customer's engineers:

• Surveyed the Customer's Roof to Develop a Practical Routing for the Ductwork, Minimizing Interference with Roof Obstacles
• Assisted Our Client's Customer to Provide a Professionally Engineered Steel Support Structure, Utilizing Existing Building Columns to Support the Load of the New Ductwork
• Designed, Fabricated, Delivered, Craned, & Assembled in Place over 700 Feet of Double Wall Insulated Ductwork & Supports


The job performed well, on time, with no surprises or extra charges. Both our client and their customer were well pleased.

Industrial Ventilation - Dust Collection System

Our client was a national manufacturer of wood products. They required an upgrade to their existing dust collecting systems at one of their East coast facilities. Toyenco, Inc. designed a Design & Build package for a 35,000 CFM Dust Collecting System to eliminate three existing individual dust collectors and connect the three individual systems to one common dust collecting system.
