JETVENT CAR PARK FANS - JISU SERIES
Testing
Thrust-air 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 requirements tested to AS4429:1999.
Wiring Diagram
See page N-9, diagram ER9
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.
Control Systems
There are two types of analogue control systems used with the
JetVent JISU 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)

SUGGESTED SPECIFICATION
The high velocity jet fans shall be of the JetVent JISU 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 mounting feet, aerodynamically designed
internal flow elements and impellers of backward-curved
centrifugal design manufactured from aluminium. They shall
comply with the air performance and high temperature
requirement of Standards AS/NZ1668.1:1998 and AS4429:1999
and shall be tested up to 200°C for 2 hours and 300°C for 30
minutes.
Performance data shall be based on tests to BS848:Part
10,1999 for thrust and BS848:Part 2, 1985 for noise.
DESCRIPTION
The JISU Series of JetVent Fans are available in 50 and 100N
thrust capacities. This range is suitable for ambient and also
high temperature applications as required in fire/smoke control
applications. All models feature a low profile housing that is
suitable for car parks with low ceiling heights. These units may
be used in conjunction with Variable Speed Drives (VSD)
for efficient speed control.
Typical Applications
Enclosed or semi-enclosed spaces that contain harmful vehicle
exhaust pollutants and require fire/smoke control. 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
Highly efficient, aerodynamically designed internal flow
elements.
O
Available with powerful 50 or 100N thrust capacities.
O
Engineered for smoke-spill applications and suitable for
ambient operating temperatures up to 80°C.
O
Compact low profile design makes it suitable for
applications with low ceiling heights.
O
Durable galvanised steel fan housing with light grey
powder coated finish as standard.
O
Integral mounting feet allows unit to be easily fitted to the
ceiling.
Smoke-Spill Standards
O
Designed to comply with the air performance and high
temperature requirement of Standards AS/NZ1668.1:1998
and AS4429:1999. Both Standards are mandatory for
smoke-spill installations.
O
Tests up to 200°C for 2 hours and 300°C for 30 minutes
have been successfully concluded.
In the case of a fire occurring, JetVent smoke-spill models will
stop operating for a predetermined time to allow occupants to
escape the building. After this time the JetVent fan will
commence operation again.
Construction
Low profile galvanised steel housing with aerodynamically
designed internal flow elements. Light grey powder coated
finish as standard. Backward curved centrifugal impeller
manufactured from durable aluminium.
Motors
Type - external rotor, squirrel cage induction motor.
Electricity supply - 415V, three-phase, 50Hz.
Bearings - sealed-for-life, ball.
Speed controllable using Variable Speed Drives which must be
bypassed in smoke control mode. Sinusoidal filters are required
for Variable Speed Drive control.
Motors are suitable for ambient conditions as well as high
temperature conditions required for smoke-control applications.
Maximum ambient temperature 80°C.
