acoustic centrifugal cabinet fans consists of 6
nominal model sizes.
All models are suitable
for direct in-line connection to industry standard
diameter circular ducting.
upon the model, the range are available with 2
or 4 pole speed, single phase motors.
All models include a remote mounted wiring terminal
box to facilitate electrical connections.
Airflow performance for the UPA series

The UPA series of fans are suitable for
many ducted noise sensitive ventilation
applications, including the ventilation of:
- Factory units.
- Cafes and bars.
All UPA fan casings are manufactured from
fabricated galvanised sheet steel and internally
lined with a 50mm thick Melamine
(M1 type) acoustic insulation material.
All models are supplied with circular ducting
connection flanges mounted on both the
inlet and discharge sides of the casing.
The UPA casing design includes a removable
cover (quick release fixings without
tools) which permits direct access to the
fan motor and impeller for servicing and
maintenance, without having to remove the
casing from the ducting.
All models are supplied with robust steel
support feet enabling the fans to be mounted
in any orientation to facilitate installation.
All UPA cabinet fans include, as standard,
low pressure forward curved centrifugal fan
impellers with a direct-drive single phase
motor (IP44, enclosed type). All motors are
suitable for speed control via voltage regulation.
