Introduction
The Nuaire ESX Belt Drive range consists of the
following units:
ESX-X (Duct Mounted, Plantroom/Roof) in line unit
ESX-R (Roof Mounted, end inlet) side discharge unit*
ESX-B (Roof Mounted bottom inlet) side discharge unit*
* larger size units have end discharge.
Units are rectangular in section. The casing is manufactured
from heavy gauge ‘Aluzinc’ aluminium-zinc coated mild steel.
A full size internally lined access panel is fitted to the top
face and this panel is fully detachable for inspection purposes.
The motor plate and frames are supported on the base by
resilient mountings allowing the fan unit to be operated
without the need for separate anti vibration fan case
mountings. The units incorporate an independent motor with
high efficiency, forward curved centrifugal impeller running
in a metal scroll. Taper locked pulleys and wedge drive belts
are employed. The motor is manufactured to BS5000 and
suitable for three phase supply.
Airflow and failure monitors are standard as is Class F
insulation. Suitable for operation in ambient temperatures
up to 40
o
C.
Handling
Handle the units carefully to avoid damage and distortion.
Eyebolts are provided on some units for lifting purposes.
If mechanical aids are used to lift the unit, spreaders should
be employed and positioned so as to prevent the slings,
webbing etc. making contact with the casing.
