DESCRIPTION
The PowerLine Series
®
of In-Line Centrifugal Fans is designed
for a wide range of duct mounted applications. They are most
suitable in commercial and industrial applications where medium
to high air pressure is required. They are available in various
speed options and 8 sizes, extending from 315 to 710mm
diameter.
Typical Applications
Commercial and industrial supply or exhaust air applications
such as shopping centres, office buildings, exhibition centres,
hotels, health centres, schools and universities.
Features
O
Robust, yet lightweight galvanised steel construction.
O
Easy to fit 35mm TDF profile flange connections.
O
Choice of external rotor or standard direct-drive
TEFC motors.
O
Large choice of speeds available.
O
Most 3-phase external rotor motors fitted are 2-speed
star/delta design.
O
To improve energy efficiency, motors can be speed-controlled
O
Motors complying with Ex d, Ex e, Ex nA and Ex tD
Standards can be fitted.
O
Can be mounted in any position.
O
A range of matched ancillaries is also available.
Construction
Galvanised steel housings with 35mm TDF profile flange
connections.
Backward-curved centrifugal impellers. DD impellers are made
from aluminium, ER impellers made from high performance
injection moulded composite plastic.
Motors
Type - can be supplied with direct-driven external rotor or
standard direct-drive TEFC motors.
Electricity supply - single or three-phase to suit a wide range of
voltages and frequencies.
Bearings - sealed-for-life, ball.
External rotor motors are fully speed-controllable using electronic
or auto-transformer controllers, however Sinusoidal filters are
required when a variable speed drive is used.
Standard direct-drive TEFC motors can be single or multi-speed
and can be speed-controlled using a variable speed drive.
See pages
O-2/3
for details on external rotor motors and pages
O-3/4
for details on standard direct-drive TEFC motors.
If standard frame motors complying with Ex d, Ex e, Ex nA and
Ex tD Standards are required, selection can be made from
these pages.
