HOW TO ORDER
DESCRIPTION
The High Capacity (HC) and Smoke-Spill (SS) Series of vertical
exhaust axial roof ventilators have been designed for use in
commercial and industrial applications. They are built to handle
clean air, toxic, noxious and explosive gases as well as handling
air at elevated temperatures. There are 10 sizes in the series
extending from 500 to 1800mm diameter.
Typical Applications
The HC model exhausts air from a wide range of commercial
and industrial installations, ranging from clean air through to
toxic, noxious and explosive gases. The SS model is designed
for high temperature air exhaust applications.
Features
O
Robust and durable galvanised steel construction.
O
Adjustable pitch impellers can provide a wide range of
performances.
O
Available in a range of speeds to suit specific applications.
O
Can be used for free air intake and ducted applications.
O
Impellers can be GRP, aluminium, nylon or anti-static
(max 1400mm dia) to suit specific applications.
O
Designed to handle clean air, toxic, noxious and explosive
gases as well as handling air at elevated temperatures
such as for smoke-spill applications.
O
All non-hazardous motors are speed-controllable using
variable speed drives.
O
Multi-speed motors, as well as motors to meet Ex d, Ex e,
Ex nA and Ex tD Standards can be supplied.
Construction
Galvanised steel cowl. Shutters are fitted as standard. Impeller
blades can be GRP (standard), aluminium, nylon or anti-static
to suit the application.
Motors
Type - squirrel cage induction motors
Electricity supply - 415V, 3-phase, 50Hz
Bearings - Sealed-for-life, ball
All standard motors in HC range can be speed-controlled using
variable speed drives.
Motors with 2-speed windings, or to meet Ex d, Ex e, Ex nA,
Ex tD or smoke-spill applications can be supplied.
See pages
O-3/7
for details on these motors.
Internal Thermal Protection
Thermistors can be fitted on request. If fitted on Smoke Spill
Series they must not operate under smoke-spill mode.
Testing
Air flow testing - 500-1000mm diameter - BS848:Part 1, 1980
1250-1800mm diameter - ISO5801:1997
Noise testing to BS848:Part 2, 1985
SMOKE-SPILL APPLICATIONS
The SS Series of smoke-spill fans has been fully tested to meet
the air performance and high temperature requirements of
Standards AS/NZS1668.1:1998 and AS4429:1999.
Discharge damper fail-open latching
An additional requirement of AS/NZS1668.1:1998 with respect to
un-sprinklered buildings (300
o
C for 30mins) requires dampers to
fail-open during smoke spill operation.
The fail-open discharge damper latches come in two forms;
the first being a manual release type requiring manual
closing after the fan has been run. The second design,
an electro-mechanical type permits the shutter latch to release
and close automatically after the fan stops.
For advice on smoke-spill wiring requirements refer to
AS/NZS1668.1:1998.
