Effective pressure control combined
with silent operation were key
demands from Cameron Balloons for
blowers used for the inflatable dome
over the
performance area at
the 2012 St Prex
classical arts festival.

These criteria
were fulfilled by a
pair of ‘intelligent’
fans supplied by Air
Control Industries.

The fans, ACI’s QB EC units, were
supplied with an electronic controller
and pressure sensor installed inside
the dome. This fan and control
package ensured the dome was
always inflated to the correct
pressure to retain shape and stability
without material being
over stressed.

The ACI system
compensates for
natural air leaks and
adjusts pressure
according to changing
ambient temperatures.

This gives on-demand
operation only from near silent fans.
