SA fans are single inlet centrifugal fans
equipped with forward curved blade.
The range comprises 9 different sizes
available in two versions according to
the rotation of the impeller.
The name of the range is RTC. The fans
are equipped with a rectangular shaped
side structure, built in “L” profiles which
strengthen the unit forming and giving a
reduced volume for the structure.
SA fans have forward curved centrifugal
impellers, tablocked on both sides to
two steel rings and to a double disk at
The blade is designed to minimize the
loss caused by air turbulence and to
obtain maximum efficiency with
minimum sound level.
All impellers are dynamically balanced.
The housings, in galvanized steel, are
formed by two side plates spot-welded
to a central scroll.
A cut-off mounted on
to the discharge prevents turbulence.
The side plates have an aerodynamic
profile and include some drill holes to
allow fixing of the base supports as well
as the motor support.
can be selected for the base support
and eight for the motor support.
The ball bearings are mounted on
rubber inserts to reduce vubration
except for the framed versions which
are filled with cast ball bearing
Operating temperature -30°C to + 85°C.
The “R” series fans are based on
standard “N” fans equipped with rectangular
side structures built with “L”
profiles which reinforce the unit, forming
a rigid cube structure.
This frame is
welded to the sides of the fan. A
number of groove-shaped drills on the
strenghthening frame corners allow for
a proper fixation.
The SAP range of belt-drive, single inlet
forward curved centrifugal fan-deck
assemblies consists of 9 nominal model
The fan scrolls encasing the centrifugal
impellers are manufactured from high
grade galvanised sheet steel.
scrolls consist of two pressed side
parts with an electro-welded rolled shell.
The SAP series are manufactured
as standard with an “L” shape profiled
galvanised steel support frame.
This support frame is welded to the
sides of the fan scroll to reinforce the
unit forming a rigid structure.
support frame in turn is welded to a
heavy gauge profiled base frame on
which the motor is mounted with a belttension
frame also includes a number of elongated
fixing holes to facilitate
mounting the complete assembly.
Models 9/4 up to 18/18 include high
quality ball bearings mounted on rubber
inserts to reduce vibration.
models 20/10 up to 30/14 include high
quality ball bearings with die cast bearing
housings for strength and durability.
The SAP range are available in 9 model
sizes and two construction variations
dependant upon the rotation of the
impeller- please enquire.
