Performance Curve - BRB12-305LS-38

Description

The Blue Rhino range of single width, single inlet (SWSI) centrifugal fans features a backward-curved laminar impeller and a heavy duty, fully welded construction. Their innovative design integrates a Variable Speed Drive (VSD) which eliminates the need for a high maintenance belt and pulley system. They are driven by a direct drive motor and are available with a long lasting hot dip galvanised finish or durable blue powder coating. The range is available in 15 impeller sizes, extending from 12 inch (305mm) to 44 inch (1120mm) diameter. Smaller sizes come in a box type design and larger sizes with a pedestal mounted motor.
