JETVENT CAR PARK FANS - JIU SERIES
HOW TO ORDER
DESCRIPTION
The JIU Series of JetVent fans are suitable for car park
installations where a low ceiling height and tight spaces make
fitting the fans particularly challenging. The CPC2 Series can
be controlled either by a Variable Speed Drive (VSD) or
two-speed switching, while the CPMF Series is suitable for
lower cost installations requiring two-speed control.
Typical Applications
Enclosed or semi-enclosed spaces that 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
Highly efficient, aerodynamically designed internal flow
elements
O
Available with powerful 50 or 100N thrust capacities
(CPMF models available with 50N thrust capacity only)
O
Compact low profile design makes it suitable for
applications with low ceiling heights
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
High/low speeds selected by switching from star to delta
electrical connection.
O
Low noise/low speed models available.
Construction
Low profile galvanised steel housing with aerodynamically
designed internal flow elements. Light grey powder coated finish
as standard. Centrifugal or Mixed-flow impeller manufactured
from durable aluminium. Electrical isolator fitted as standard.
Motors
Type - squirrel cage induction motor.
Electricity supply - 415V, three-phase, 50Hz.
Bearings - sealed-for-life, ball.
2-speed motor.
Speed control: CPMF models - Two speed system using relays
to drive contactors.
CPC2 models - Using 0 to 10 VDC outputs
to proportionally drive VSD
or two speed system using
relays to drive contactors.
Maximum ambient temperature 70°C
See pages
O-3/4
for details on these motors.
Internal thermal Protection
CPMF models - Manual reset protection is supplied as standard
on these units.
CPC2 models - Thermistors can be supplied on request.
SUGGESTED SPECIFICATION
The high velocity jet fans shall be of the JetVent JIU 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 and aerodynamically
designed internal flow elements. Impellers shall be of Mixed-flow
or backward-curved centrifugal design manufactured from
aluminium. They shall produce 50 or 100 Newtons of thrust
and include a 2-speed star/delta motor.
Performance data shall be based on tests to BS848:Part 10,1999
for thrust and BS848:Part 2, 1985 for noise.
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.
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 JIU Series:
CPMF and CPC2 models :
Two speed system using relays to drive contactors
connected to the fans (See page F-14)
CPC2 models:
Variable speed system using 0 to 10 Vdc outputs to
proportionally drive VSDs (See page F-15)
