Reduce Power Costs

Your current aeration blower system may be the
biggest single opportunity to reduce your power overhead.

When installed, your aeration blowers were matched
for best efficiency at the original performance
conditions. Times change, conditions change. GE looks
at today’s and projected future conditions to analyze
and establish updated best performance requirements
for the blowers and complete aeration control – for
example a 10 psig blower running at 8 psig uses 6%
more power than a blower designed for 8 psig.
