Performance Curve - BRH21-535LS-24

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.

The Blue Rhino is intended to be used with a Variable Speed Drive (VSD) to achieve the desired speed, eliminating the need for a high maintenance belt and pulley system. They are driven by a direct drive motor and are available with a durable blue powder coating by default or selected with a long-lasting hot dip galvanised finish.

The range is available in 19 impeller sizes, extending from 12 inch (305mm) to 44 inch (1120mm) diameter. There are three housing designs available to suit a wide range of duties.

Features

Casings and impellers are made of high strength fully welded mild steel.
VSD which eliminates the need for high maintenance belt and pulley system.
VSD can be factory pre-configured to suit application, creating a time saving plug and play system.
Fitted with inlet spigot and discharge flange.
Comes standard with inspection hatches and drain plugs.
Clockwise impeller rotation is standard, anti-clockwise rotation is available upon request.
Driven by a reliable direct drive motor design.
Comes with a durable blue powder coating by default.
Alternatively, it can be selected with a long-lasting hot dip galvanised finish.
