Industrial Dampers

Often used in dust collection, heating and other air control applications, we custom design and build dampers that stand up to the most grueling industrial environments.  High temperature and pressure applications are no match for the Interstate construction, we urge you to take a look for yourself in our photo gallery.

Butterfly & Backdraft Dampers
With various shape and size options from round to rectangular, our butterfly dampers can fit just about any opening.  We also offer manual, electrical or pneumatic control options for fast acting operation and easy access to the bearings for routine maintenance.

Isolation Dampers
Custom designed to isolate a particular product or air stream from contaminating the atmosphere of another; the Interstate Isolation Dampers are reinforced to prevent warping or bending under pressure. The manual override and position indicators make them user-friendly.

Atmospheric Tee Dampers
This style of damper allows you to divert an air stream to atmosphere or other process streams quickly. If needed, a booster fan can be supplied to increase velocity in the ductwork and slave linkage added to allow for simultaneous blade control. Our weather caps and risers can withstand the most inclement weather conditions while minimizing backpressure on a system fan.

Slide Gates
Used in a wide variety of applications, the slide gate dampers are available in a round or rectangular design with safety gates and variable speed options.
