Donald Gabriel has over 25 years of experience in the application and design of dampers for the control, isolation and modulation of flue gases.  Having worked for several major dampers including Air Clean Damper Company (ACDC), Pathway, EFFOX, and Bachmann, a wealth of knowledge few share in the design and application of dampers from several different design and product philosophies is drawn upon.

Do you need a damper expert on your staff for your next project to insure that you get the quality and level of equipment needed?  If you have field issues or need an independent damper resource, I also can provide that service.
