Types/Model MicroAir I MicroAir II MicroAir IV Dual MicroAir I Dual MicroAir II Dual MicroAir IV MultiAir 3-channel MicroAir I MultiAir 3-channel MicroAir II MultiAir 3-channel MicroAir IV MultiAir 4-channel MicroAir IV Options available on MicroAir II & IV units: Digital Display Voltage output 4-20 ma output Remote Control (MAII) For precise control of outside diameter during tubing extrusion, the MicroAir line of air pressure regulators and controllers regulates air pressure to an exact set point. Stable, reliable 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. Features: • Regulates air pressure to a set point • Controls outside diameter • Precision output pressure display • Ultra Low ranges: 0 - 3” of water 0 - 5” of water 0 - 15” of water 0 - 30” of water 0- 50” of water 0 - 3 psi 0 - 5 psi Others available upon request. • Stainless steel enclosure • Hysteresis free regulating action auto control models • High speed model that accepts a 0-10 volt input for control • Multiple channels for multi-lumen tubing. Models Available: MicroAir I Manual model controlled by a single knob (30 turn adjustment) MicroAir II Accepts contact closure inputs. Up/Down manual control dual speed push buttons on the front or motorized Up/Down remote control ready for solid state or mechanical relays by internal screw terminals. Dual selectable voltage input 110 or 220 volt. Zero to Full Scale in approximately 2 minutes. MicroAir IV Dual-state using a logic signal or Linear mode using a 0-10 volt input to control pressure by extrusion line equipment such as the PLC. Designed 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 0.1 second (typically 20-30 msec).
