Case Study: Sand Blasting Industry

C&W Manufacturing, a class-leading provider of dust filtration and recapture systems, was contracted by a Texas-based refurbishing plant for development, building, installation, and integration of four cartridge pulse collectors. These advanced filtration systems are capable of processing up to 40,000 CFM with 99.99% efficiency, and easily provided the performance and capacity that this customer required.

After an on-site analysis, we made necessary design modifications that allowed for better facility integration. The customer ordered two 40,000 CFM units and two 20,000 CFM units, each adapted to work with collector bins. Production of the four units as well as full operational testing followed. Supervised installation, handled by our own personnel, consisted of detailed drawings for installation, setup, ductwork, and training of customer personnel in charge of operation and maintenance.

Through extensive attention to customer needs and high quality production, C&W Manufacturing is able to reliably bring high performance air filtration solutions. To learn more about our role in this project, or to discuss how our equipment can benefit your facilities, contact us today.
