 Features
|
- The range covers sizes 200 - 1000mm diameter with Elta axial flow impellers.
|
 Construction
|
- The AMS range of roof units are precision manufactured from pre-galvanised sheet metal.
- The wind band and shutter have been aerodynamically designed to produce the minimum possible resistance to airflow whilst offering full protection.
|
 Motors
|
- Totally enclosed IP55 tested to BS4999 and BS5000 and suitable for exposure to weather.
- Standard voltages are 400 volt and 230 volts nominally.
- Single-phase IP55 speed controllable motors are available.
|
Special features
|
- Refer to p D-2. High temperatures smoke spill fans are available.
- Special voltages, speeds and classes are available on request.
|
Selection procedure
|
- The units are selected of the standard AMS axial flow curves allowing a K factor of 1.0 for the RSC.
