AxFlow now offers a new
approach to reducing air
consumption for larger size
air-operated double diaphragm
(AODD) pumps. Using the MizAir, it
is said to be possible to reduce air
consumption by up to 50% with
minimal loss of fluid flow.

Designed for close-coupling to the
pump,MizAir requires just a 24VDC
power supply. A self-powered ATEX
version will follow later in 2010.
The microprocessor controlled
MizAir consists of a high-flow
normally open two-way valve and an
electronic control unit. Valve and
control unit operate to deliver
precisely timed pulses of air to the
pump at the start of each pump
stroke. Because less air enters the
pump there is less air to exhaust and
this helps the pump to start its next
cycle as there is less resistance to the
return stroke. There is also the
benefit of a reduction in the noise
level of the exhaust air.

Low on power consumption,
MizAir is an intelligent device and
can continuously monitor the speed
and other operating parameters of
the pump and make adjustments to
the valve timing as required.
