SMOKE-SPILL APPLICATIONS
Smoke-spill fans have to be tested to Standard AS4429:1999 to conform with the
requirements of AS/NZS1668.1:1998. To meet the Standards Fantech conducted an
extensive series of tests covering both air flow and temperature. The air flow tests for
sizes 315mm to 1000mm diameter conformed to BS848:Part 1, 1980 and to ISO5801
for sizes 1.0m to 2.0m. The temperature tests were conducted in accordance with
AS4429:1999, although the 300°C tests were extended from 0.5 hours to 2 hours to
ensure we met the needs of some specifications.
The outcome of the series of tests is that we can supply fans ranging in diameter from
315mm to 2000mm at speeds as high as 2 pole depending on size and, for both 50
and 60Hz supply that fully comply with the Standards in all respects.
The following conditions can be met:-
Discharge damper fail-open latching
An additional requirement of the Standards relates to the function of the discharge
dampers in unsprinklered buildings. Fantech has met the requirements with two
designs, the first being a manual release type requiring manual closing after the fan
has been run. These may be used for dedicated smoke spill fans. The second design,
an electro-mechanical arrangement, permits the shutters to close automatically after
the fan stops. These are recommended for use on dual-purpose ventilation/smoke-spill
fans. Fantech has provisional patents for both designs.
For advice on Smoke-Spill wiring requirements, refer to the above Standard.
