Pea Soup’s PS
Centrifugal Fan is a very impressive, smoke
sealed, continuously rated industrial duty blower for distributing smoke
rapidly and evenly through ductwork into training buildings,
simulators etc. or forcing smoke down pipes or duct
work, pressurising containers for smoke leak visualisation
The unit is supplied on a stand appropriate
to the type of Pea Soup smoke generator being used (PS27 Dragon, PS31 or PS33), with a guarded inlet
and a 75mm outlet spigot as standard (50mm outlet also
available). Up to 30 metres of 75mm diameter ductwork
can be used with this blower. We supply lined, flexible ducting hose in 10 metre lengths for this. A 100mm outlet spigot can also be ordered to allow connection to a system of 100mm uPVC waste pipe to act as a smoke ducting system for installations.
These fans are installed in fire training centres that are 20 years old and have accumulated over 1,000,000 operating hours. This is a high quality and incredibly reliable fan.
It is normally supplied in its 115/240v
50/60hz form, although other options are available.
The angle of discharge can be specified the time of
ordering. The default angle of discharge is L90 (outlet
parallel with ground, see photo, left).

The Correct Spacing Relationship Between Smoke Machine and Centrifugal Fan
For the best performance, it is important that the fan is sited in front of the smoke system, as far away from the smoke
generator as possible whilst capturing the entire smoke plume. ie distance A shown in the diagram above should be maximised. This distance depends on
the length / smoothness etc of the ducting used (and the frictional losses therefore present) and so it is impossible to set until
the ducting has been attached to the centrifugal blower.
