  Bellmouths

Bellmouth fittings are designed to the highest engineering standards for maximum performance. They are used as a take-off for a fast, solid, and highly efficient connection. This conversion fitting, from a flat plenum or duct into Spiral pipe greatly reduces turbulence and noise. The pressure drop characteristics are superior to any other design.
