MicroAir
Ultra Low Air Pressure Regulator and Controllers
For precise control of tubing outside diameter
during extrusion, the MicroAir line of air
pressure regulators and controllers regulates air
pressure to an exact set point. Pressure is
maintained for widely varying flow rates such
as when a cut is made, etc. The “force balance
regulator” provides instantaneous response to
changes in flow rate and maintains a set
pressure with flow rates from near zero up to
the rated maximum.

MicroAir IV
Designed for the use in manufacturing bump and
tapered tubing where the pressure must be
instantaneously switched or varied in a controlled
way. A precision voice-coil linear motor with
viscostic damping ensures optimum speed and
stability. Control knobs for Hi and Low set points.
Responds to a step of 50% of full scale in less the
