Alpha Supply Series – AE504S
Performance Curve - AE504S
Description
The Alpha Series of supply air roof units have been designed for use in free intake or ducted installations. These robust but lightweight units are fitted with bird mesh as standard to prevent debris and birds entering the building and interrupting motor operation. There are 10 models in the series extending from 200 to 630mm diameter.
Features Robust, corrosion-resistant construction with high performance axial flow impellers.
Large choice of speeds available.
The MV units have durable powder-coated steel blades. The AD/E units have GRP blades as standard with an option of aluminium, nylon or anti-static.
Can be mounted at angles up to 30°.
Some 3-phase motors are 2-speed star/delta design as standard.
Speed-controllable using electronic or auto-transformer controllers.
