Model BRI-M


The BRI-M was developed as a response to our customers desire for an economical industrial Butterfly damper which could be used in utility applications.  They specifically requested that the dampers use the same commercially available angle flanges as was being used on their ducting to facilitate problem free installation.

The model BRI-M is available in carbon and standard stainless steels from 8" diameter. through 50" diameter in 1" increments and 52" through 72" diameter in 2" increments. Designs and material options are available for temperatures to 1600° F.
