Standard Bellmouth

Fast, Solid, highly efficient connections at a low overall cost!

Bellmouth fittings are designed as a take-off from a rectangular duct or plenum to round spiral pipe.  This is a recognized formula fitting (radius =.2 x neck diameter), designed to the highest engineering standard for maximum performance.  Turbulence and noise are reduced, and pressure drop characteristics are superior.

“A” Dimension is 1/8 undersized to fit into spiral pipe.  Available in most sizes in aluminum, paint grip, and stainless steel. 

(Oval and Rectangular Bellmouth Also Available)
