Features and Benefits
Design
The Heritage Smoke-spill Series has been developed and tested for hot smoke exhaust applications. It features a removable windband which provides easy access for cleaning and maintenance. To maintain reliable operation, motor is mounted out of the airstream. It can also be used for dual purpose in standard exhaust installations.
Smoke-Spill Standards
Designed to comply with the air performance and high temperature requirement of Standards AS/NZS1668.1:1998 and AS4429:1999. Both Standards are mandatory for smoke-spill installations. Tests up to 300°C for 2 hours have been successfully concluded. Backdraft dampers are not fitted to these units so fail-open latching devices are not required.
Internal Thermal Protection
Thermistors can be fitted on request. If fitted they must not operate under smoke-spill mode.
Testing
All units are tested to ISO5801:2007 (for airside performance) and ISO3744:2010 (sound performance).
Specification
Construction
Cowls are of galvanised steel.
Impellers
Impellers are backward-curved centrifugal design.
Motor
The fans are built with standard TEFC squirrel cage induction motors with sealed for life ball bearings. The motor requires an electricity supply of 415V, three-phase, 50Hz. Motors are selected to suit the nominated smoke-spill temperature requirements as prescribed in AS/NZS1668.1:1998.
Control
Multi-speed motors can be supplied.
