JETVENT CAR PARK FANS - JV SERIES
F-4
F
DESCRIPTION
The JV Series of JetVent axial fans have been designed
to provide effective ventilation in most spaces that contain
harmful vehicle exhaust pollutants. They can be supplied
for uni-directional or truly reversible air flow and are available
in 2 sizes, 315mm and 400mm diameter. Units approved
to AS4429:1999 for high temperature smoke exhaust
are also available.
Typical Applications
Enclosed or semi-enclosed spaces that may contain harmful
vehicle exhaust pollutants. These spaces include commercial
and residential car parks, loading bays, drive through facilities
and indoor go-kart tracks. Can also increase cross-flow
ventilation in open car parks.
Features
O
Available with single (high) or 2 speed (high/low) motor.
O
Integral aerodynamically designed silencers provide quiet
operation.
O
Bell mouth inlet and outlet optimises performance.
O
Units can be speed controlled using Variable Speed
Drives.
O
Can be supplied for uni-directional or truly reversible
air flow.
O
Fitted with a high performance aerofoil impeller.
O
Durable galvanised steel housing with light grey powder
coated finish as standard.
O
Integral mounting feet allows unit to be easily mounted
to ceiling.
O
Electrical isolator fitted on ambient temperature units.
Construction
Galvanised steel housing with integral aerodynamically
designed silencers. Light grey powder coated finish is standard.
Axial flow aerofoil impellers manufactured from aluminium.
Motors
Type - squirrel cage induction motor.
Electricity supply - 415V, three-phase, 50Hz.
Bearings - sealed-for-life, ball.
Single or 2-speed as nominated.
Speed controllable using Variable Speed Drives.
Standard motors are suitable for ambient conditions up to 40°C.
Units for high temperature conditions, such as smoke-control,
are available.
See pages
O-3/4
for details on these motors.
Internal thermal Protection
Thermisters can be provided on all motors except where
Standards prohibit their use.
Testing
Thermistors performance based on tests to BS848 Part 10,1999:
"Fans for general purpose - Performance testing of jet fans".
Noise data based on tests to BS848:Part 2, 1985.
High temperature tests to AS4429:1999.

Special Note
Jet fans should be treated as an Alternative Solution within the
National Construction Code (NCC)(formerly the BCA) from a fire
and smoke control perspective (in addition to the ventilation
requirements). Therefore the fire engineer on the project would
need to add the car park ventilation design into their fire
engineering report for the project and ensure that they meet the
relevant BCA performance clauses. For more information please
refer to the JetVent “Practical Guide for Selection and
Application” or the Fantech website.
Smoke-Spill Applications
Smoke-spill models have been fully tested to meet the air
performance and high temperature requirements of Standards
AS/NZS1668.1:1998 and AS4429:1999.
In the case of a fire occurring, smoke-spill models will stop
operating for a predetermined time to allow occupants to
escape the building. After this time the fan will commence
operation again.
Control Systems
There are two types of analogue control systems used with the
JetVent JV Series:
O
Two speed system using relays to drive contactors
connected to the fans
(See page F-14)
O
Variable speed system using 0 to 10 Vdc outputs
to proportionally drive VSDs (
See page F-15)
The high velocity axial jet fans shall be of the JetVent JV Series
as designed and manufactured by Fantech Pty Ltd. and be of
the model number shown. The housing shall be of galvanised
steel with a light grey powder coated finish as standard. They
shall incorporate aluminium axial impellers of aerofoil design
and aerodynamically engineered silencers. They shall be single
or 2-speed as nominated.
Performance data shall be based on tests to BS848:Part
10,1999 for thrust and BS848:Part 2, 1985 for noise. Units
for smoke-spill applications shall be tested to AS4429:1999.
